14 Best Single Dumbbells for Home Workouts in 2027

The best single dumbbell overall in this roundup is the Amazon Basics Rubber Hex Dumbbell, 20 lb, a straightforward fixed-weight choice for common strength exercises. For lighter training, Marcy’s neoprene single dumbbells cover small increments from 1 to 10 pounds, while the BowFlex SelectTech 552 offers a space-saving adjustable option for a broader range of workouts. Your main tradeoff is choosing a fixed weight with a simple, stable feel or an adjustable design that takes up less space but adds moving parts. Handle comfort, flooring, and whether you need one weight or a matched pair matter just as much as the number on the dumbbell. Read on for the full breakdown and guidance on choosing the right single dumbbell for your routine.

• Marcy’s neoprene lineup is the clearest match for lighter training, with single weights from 1 to 10 pounds that let buyers select a load for rehabilitation-style movements, beginners, or high-repetition work.
• Adjustability separates the BowFlex and Amazon Basics adjustable models from the fixed dumbbells: they offer multiple loads in one unit, but buyers trade the simplicity of a fixed weight for selector hardware and a storage base.
• The 3–100-pound Marcy Hammertone range and 5–70-pound Marcy Classic Rubber Hex range suit different lifting needs; their broad ranges are useful for building a set, while a single weight purchase may not provide the progression a full program needs.
• Several close-weight Amazon Basics hex options make grip, finish, and intended training load the deciding factors, rather than assuming a 10-, 15-, 20-, or 25-pound dumbbell is universally best.

More Details on Our Top Picks

1. Amazon Basics Rubber Hex Dumbbell, 20 lb

   

   Best Overall

   View Latest Price

   The 20-pound Amazon Basics Rubber Hex Dumbbell is my strongest all-around pick for someone who wants one substantial fixed weight for home or gym strength work. Its rubber-encased cast-iron heads and hex shape help protect surfaces and keep the dumbbell from rolling between sets, while the contoured, textured handle gives a more shaped grip than the straight knurled handle on the Marcy Hammertone Cast Iron Hex Dumbbell. That makes this a practical choice for varied exercises, including rows, presses, and lunges. The tradeoff is its fixed 20-pound load: beginners may find it heavy, and lifters who need gradual progression will need other weights. It is also sold as one dumbbell, so bilateral exercises require a second purchase.

   Pros:

   • Hexagonal rubber-coated heads resist rolling and help protect floors
   • Contoured handle with textured grip supports a secure hold
   • 20-pound load suits a range of moderate-strength exercises
   • Suitable for home or gym use

   Cons:

   • Fixed at 20 pounds, so it cannot support gradual load changes
   • One dumbbell is included rather than a pair
   • Its weight may be too much for beginners or lighter accessory work

   Best for: Home lifters who already handle moderate weights and want one versatile, stable dumbbell for full-body exercises.

   Not ideal for: New exercisers who need very light resistance or lifters seeking adjustable weight progression from a single purchase.

   • Brand:Amazon Basics
   • Weight:20 lb
   • Material:Rubber-encased cast iron
   • Handle material:Rubber
   • Handle diameter:1.35 in
   • Dimensions:12.1 × 4.9 in (L × W)
   • Pieces:1
   • Model number:CD-20LB
   Our verdict

   “Choose this for a sturdy, versatile 20-pound single dumbbell, but skip it if you need lighter starting resistance or adjustable loading.”

2. Marcy Neoprene Dumbbell, 10 lb, Single

   

   Best for Everyday Home Training

   View Latest Price

   The Marcy 10-pound Neoprene Dumbbell suits home workouts that call for a manageable fixed weight and a comfortable coated handle. Its textured neoprene finish offers a softer-feeling grip than the rubber handle on the Amazon Basics 15-Pound Rubber Hex Dumbbell, while the no-roll head helps keep it put between exercises. At 10 pounds, it also fills a useful middle ground between the very light Marcy 2 lb Neoprene Dumbbell and heavier rubber hex options. The main compromise is that neoprene can show wear with rough handling, and this is a single dumbbell rather than a pair. Since the load is fixed, it is better for steady, focused routines than for anyone who wants one purchase to cover a wide range of strength levels.

   Pros:

   • Textured neoprene coating provides a secure, comfortable grip
   • No-roll head stays in place between sets
   • Rust-resistant finish suits home storage
   • 10-pound weight offers more resistance than the 2-pound Marcy neoprene model

   Cons:

   • Sold as one dumbbell, not a pair
   • Fixed at 10 pounds, limiting progression and exercise range
   • Neoprene coating may be less suited to rough or heavy-duty handling than rubber-coated iron

   Best for: Home exercisers who want a comfortable 10-pound hand weight for controlled strength circuits and accessory work.

   Not ideal for: Lifters who need heavier resistance, adjustable loading, or a matched pair included in one purchase.

   • Brand:Marcy
   • Weight:10 lb
   • Quantity:1 dumbbell
   • Core material:Cast iron
   • Coating and handle material:Neoprene
   • Handle diameter:1 in
   • Dimensions:8.3 × 3.7 in
   • Model:INE-010
   Our verdict

   “Pick this for comfortable, moderate-load home workouts, but choose a heavier hex dumbbell or adjustable model for long-term progression.”

3. Marcy Hammertone Cast Iron Hex Dumbbell, 3–100 lb

   

   Best for Weight Progression

   View Latest Price

   For a buyer choosing a single dumbbell now but expecting to add loads later, the Marcy Hammertone Cast Iron Hex Dumbbell stands apart because the same design is offered across a 3–100-pound range. That makes it easier to build a consistent set over time than with the fixed-weight Amazon Basics 20-Pound Rubber Hex Dumbbell. The hexagonal heads help prevent rolling, and the knurled cast-iron handle provides a direct, secure texture without a rubber or neoprene covering. That bare-metal feel is also the key tradeoff: it may be less comfortable for high-repetition work or users who prefer a softer grip. It is sold individually, so matching both hands means buying two, and the listed dimensions and weight describe a specific item rather than every size in the range.

   Pros:

   • Available in a broad 3–100 lb range for building a consistent collection
   • Hexagonal heads help prevent rolling and support compact storage
   • Knurled handle offers a secure textured grip
   • Cast-iron construction avoids a soft coating that can wear

   Cons:

   • Sold individually, so a pair requires buying two
   • Bare cast-iron handle may feel uncomfortable without gloves
   • A fixed-weight dumbbell cannot replace an adjustable set for varied loading

   Best for: Lifters building a matching dumbbell collection over time who value knurled metal grip and a broad range of available loads.

   Not ideal for: Beginners who want a soft-coated handle, or buyers who need a pair or adjustable weight in one purchase.

   • Brand:Marcy
   • Material:Cast iron
   • Available weights:3–100 lb
   • Unit count:1
   • Item weight:5 lb
   • Handle:Knurled cast iron
   • Head shape:Hexagonal
   • Handle diameter:1 in
   • Dimensions:8.63 in L × 2.5 in W
   Our verdict

   “Choose this if you plan to build a collection around one durable cast-iron design, but favor a coated model for a softer grip.”

   → See it on Amazon →

4. Amazon Basics 15-Pound Rubber Hex Dumbbell

   

   Best Midweight Rubber-Coated Pick

   View Latest Price

   The Amazon Basics 15-Pound Rubber Hex Dumbbell occupies the useful space between the 10-pound Marcy Neoprene Dumbbell and the 20-pound Amazon Basics Rubber Hex Dumbbell. That middle load can suit lifters who have outgrown lighter hand weights but are not ready for 20 pounds across every movement. Its rubber-encased cast-iron heads and hex ends give it the stable, floor-friendlier setup shared by its Amazon Basics counterpart, while the textured contoured handle supports a comfortable hold. Unlike the neoprene Marcy, this model uses a rubber handle and a larger, heavier construction. The tradeoffs are straightforward: it is fixed at 15 pounds and sold singly, so it does not provide a matched pair or built-in progression. Buyers who need a lighter accessory weight should choose the Marcy 2-pound option instead.

   Pros:

   • 15-pound load bridges lighter weights and the 20-pound Amazon Basics model
   • Rubber-encased cast iron combines a sturdy core with coated heads
   • Hexagonal ends help prevent rolling during storage
   • Textured, contoured handle supports a non-slip grip

   Cons:

   • Fixed at 15 pounds, with no option to adjust resistance
   • Sold as one dumbbell rather than a pair
   • Bulkier than the lighter Marcy neoprene hand weights

   Best for: Intermediate home exercisers who want a single 15-pound dumbbell as a step between light hand weights and heavier lifting.

   Not ideal for: Beginners seeking very light resistance or buyers who want multiple loads or a pair in one purchase.

   • Brand:Amazon Basics
   • Weight:15 lb
   • Material:Rubber-encased solid cast iron
   • Handle material:Rubber
   • Handle diameter:1.34 in
   • Dimensions:12 × 4.5 in (L × W)
   • Pieces:1
   • Color:Black
   Our verdict

   “Choose this as a stable midweight step-up for home strength work, but pass if you need a lighter load or more than one weight.”

5. Marcy Neoprene Dumbbell, 2 lb, Single

   

   Best for Light Accessory Work

   View Latest Price

   The Marcy 2-pound Neoprene Dumbbell is the lightest-focused choice in this group, suited to gentle resistance, higher-repetition movements, and exercises where a 10- or 15-pound dumbbell would be too much. Its neoprene-coated cast-iron core provides a textured, slip-resistant grip, while the no-roll head helps keep the small weight from wandering between sets. Compared with the Marcy 10-pound Neoprene Dumbbell, this one is easier to handle for light shoulder or arm work, but it offers far less room to progress. The listing includes only one dumbbell, so two-handed routines call for a second unit. Buyers seeking a general-purpose strength weight should move up to a heavier option; this model is best treated as a specialized light load rather than a single dumbbell for every exercise.

   Pros:

   • Very light 2-pound load suits controlled, low-resistance movements
   • Textured neoprene coating supports a slip-resistant grip
   • No-roll head helps keep it in place between exercises
   • Compact dimensions make it easy to store

   Cons:

   • Limited resistance quickly restricts strength progression
   • Sold individually rather than as a pair
   • Too light for many compound or heavier strength exercises

   Best for: Beginners, older adults, or rehabilitation-focused exercisers who need a very light hand weight for controlled movements.

   Not ideal for: Strength trainees seeking muscle-building resistance or one dumbbell that can serve across moderate and heavy exercises.

   • Brand:Marcy
   • Weight:2 lb
   • Quantity:1 dumbbell
   • Material:Cast iron with neoprene coating
   • Handle material:Neoprene
   • Handle diameter:1 in
   • Dimensions:5.5 × 2.4 in
   • Model number:INE-002
   Our verdict

   “Choose this for light, controlled accessory work, but select the 10-pound Marcy or a rubber hex model for broader strength training.”

6. Amazon Basics Adjustable Dumbbell 25 lb

   

   Best Adjustable Pick for Small Spaces

   View Latest Price

   The Amazon Basics Adjustable Dumbbell offers five settings from 5 to 25 pounds in one unit, making it a more space-conscious choice than keeping several fixed dumbbells on hand. Its turn-handle adjustment lets you change the load without swapping individual plates, while the safety mechanism helps secure them during use. Compared with the fixed-weight Amazon Basics Rubber Hex Dumbbell, 25 lb, this model better suits workouts that move between lighter and heavier exercises; the hex dumbbell, by contrast, is simpler and has no adjustment mechanism. The tradeoff is its 25-pound ceiling, which may limit strength progression, and this is still just one dumbbell. Buyers seeking matched two-handed work need a second unit, so the space saving comes with a higher equipment cost and more adjustment hardware to manage.

   Pros:

   • Five weight settings reduce the need to store several fixed dumbbells.
   • Turn-handle adjustment makes changing loads straightforward.
   • Safety mechanism helps keep the plates secured.
   • Alloy steel construction is suited to repeated home workouts.

   Cons:

   • The 25-pound maximum may be too light for stronger lifters and continued progression.
   • Sold as one dumbbell, so balanced two-arm training requires another unit.
   • Adjustment hardware is less simple than a fixed-weight hex dumbbell.

   Best for: Home exercisers with limited storage who want one dumbbell for varied movements between 5 and 25 pounds.

   Not ideal for: Advanced lifters who need loads above 25 pounds or buyers who want a matched pair in one purchase.

   • Weight settings:5, 10, 15, 20, 25 lb
   • Quantity:1 dumbbell
   • Material:Alloy steel
   • Handle material:Nylon and fiberglass
   • Adjustment:Turn-handle
   • Safety feature:Anti-drop plate mechanism
   • Color:Black
   • Model number:ADB-25LB
   Our verdict

   “Choose this single adjustable dumbbell if storage is tight and 5–25 pounds covers your training needs.”

   → See it on Amazon →

7. Amazon Basics Rubber Hex Dumbbell, 25 lb

   

   Best Fixed-Weight Pick for Everyday Strength Training

   View Latest Price

   This 25-pound rubber hex dumbbell is the straightforward choice for buyers who already know the load they need: solid cast iron provides a fixed weight, rubber-coated hex heads help limit rolling, and the contoured textured handle supports a secure grip. Unlike the adjustable Amazon Basics Adjustable Dumbbell 25 lb, it has no settings to change or plates to lock in place, which makes it a simpler option for repeated sets at one weight. That simplicity also means less flexibility: it cannot cover lighter exercises or scale upward as strength improves. The rubber coating can help protect floors and reduce clatter compared with bare metal, but the dumbbell still takes up dedicated storage space. Since it is sold singly, two-handed paired exercises require a second dumbbell.

   Pros:

   • Solid cast iron heads provide a fixed, familiar training load.
   • Hexagonal shape helps prevent the dumbbell from rolling away.
   • Rubber coating can reduce noise and protect floors.
   • Textured, contoured handle supports a secure grip.

   Cons:

   • Fixed at 25 pounds, so it cannot adapt to lighter exercises or future strength gains.
   • Sold as one dumbbell rather than a pair.
   • Requires more storage space than a single adjustable dumbbell with multiple settings.

   Best for: Home or gym lifters who want a dependable 25-pound fixed weight for rows, presses, and other strength exercises.

   Not ideal for: People who need several weights in a small storage area or want a matched pair from a single purchase.

   • Weight:25 lb
   • Quantity:1 dumbbell
   • Head material:Cast iron
   • Coating:Rubber
   • Handle diameter:1.32 in
   • Dimensions:12.5 × 5.25 in
   • Shape:Hexagonal heads
   • Model number:CD-25LB
   Our verdict

   “Pick this model if you want a simple, durable 25-pound dumbbell and do not need adjustable loading.”

8. Marcy Neoprene Dumbbell Hand Weight, 5 lb, Single

   

   Best for Light Exercise and Beginners

   View Latest Price

   At 5 pounds, this Marcy is aimed at light resistance work rather than heavier strength training. Its textured neoprene coating gives the handle a grippy surface, while the no-roll head helps keep the dumbbell where it is set down—useful in small workout areas. Compared with the Marcy Colored Neoprene Dumbbell Hand Weights (6 lb, Single), this is the lighter choice for beginners, mobility routines, or exercises where control matters more than load. The difference is only one pound, so buyers close to either weight should choose based on their actual exercise needs rather than expect a major change in versatility. It is a fixed-weight single, which limits progression and requires another unit for paired movements. Its compact size is convenient, but it will not replace a heavier dumbbell for progressive strength work.

   Pros:

   • Light 5-pound load suits controlled movements and entry-level resistance work.
   • Textured neoprene coating supports a non-slip grip.
   • No-roll head helps keep the dumbbell in place between sets.
   • Rust-resistant design suits regular home use.

   Cons:

   • Fixed at 5 pounds, limiting progression as strength increases.
   • Sold as one dumbbell, so paired exercises require another purchase.
   • Too light to serve as a general-purpose strength-training weight for many lifters.

   Best for: Beginners and home exercisers looking for a light single weight for controlled arm exercises, mobility work, or low-load routines.

   Not ideal for: Lifters focused on progressive strength training or shoppers who need a pair without buying a second dumbbell.

   • Weight:5 lb
   • Quantity:1 dumbbell
   • Material:Neoprene
   • Handle diameter:1.25 in
   • Dimensions:7 × 3.5 in
   • Head design:No-roll
   • Features:Non-slip, rust resistant
   • Target body part:Arms
   Our verdict

   “Choose this single 5-pound dumbbell for light, controlled training, not as a long-term strength progression tool.”

   → See it on Amazon →

9. Marcy Colored Neoprene Dumbbell Hand Weights (6 lb, Single)

   

   Best Neoprene Pick for a Small Step Up

   View Latest Price

   This 6-pound single dumbbell fills a narrow but useful spot between light beginner weights and heavier fixed options. Its cast iron core gives it a defined load, while the neoprene coating adds a comfortable, grippy surface and helps soften contact with floors. Compared with the 5-pound Marcy Neoprene Dumbbell Hand Weight, this model provides a small increase for users who have outgrown the lighter option but are not ready for a larger jump. The difference is modest, and neither dumbbell offers adjustable resistance, so progression means buying another weight. Its no-roll head and rust-resistant construction make it practical for home workouts, though the single-unit listing is a drawback for paired exercises. Choose it for light training at a specific load, not as a flexible substitute for a full set.

   Pros:

   • 6-pound load offers a small step up from a 5-pound hand weight.
   • Neoprene coating provides a comfortable, non-slip grip.
   • No-roll head helps prevent the dumbbell from moving when set down.
   • Cast iron core and rust-resistant construction suit repeated home use.

   Cons:

   • Fixed weight offers little room to progress without buying additional dumbbells.
   • Sold as a single unit, so two-arm paired work requires a second purchase.
   • The small increase over a 5-pound dumbbell may not suit buyers who need a substantial change in resistance.

   Best for: Home exercisers who have outgrown a 5-pound hand weight and want a slightly heavier fixed dumbbell for light resistance work.

   Not ideal for: Buyers seeking adjustable loading, heavier strength-training weights, or a ready-made pair.

   • Weight:6 lb
   • Quantity:1 dumbbell
   • Core material:Cast iron
   • Coating:Neoprene
   • Handle diameter:1.25 in
   • Dimensions:7.3 × 3.5 in
   • Color:Eggplant
   • Features:Non-slip, no-roll head, rust resistant
   Our verdict

   “Choose this 6-pound Marcy if you want a modest step up from light beginner weights and are comfortable buying one dumbbell at a time.”

   → See it on Amazon →

10. BowFlex Results Series SelectTech 552 Adjustable Dumbbell

    

    Best Premium Adjustable Pick for Broad Weight Progression

    View Latest Price

    The BowFlex SelectTech 552 has the broadest stated weight range in this group, moving from 5 to 52.5 pounds with quick-adjustment dials. That range gives it more room for progression than the Amazon Basics Adjustable Dumbbell 25 lb, whose lower ceiling may leave stronger users wanting more. The dial system and included storage trays also let one unit stand in for several fixed dumbbells, which can free up space in a home gym. A locking system and non-slip ergonomic handle address stability and grip, but an adjustable design still has more components than a fixed hex dumbbell such as the Amazon Basics 25-pound model. The maximum remains 52.5 pounds, and the listing describes one dumbbell, so matched workouts call for a second unit. JRNY access is included for only two months, making the included digital access temporary rather than a lasting reason to buy.

    Pros:

    • Weight range from 5 to 52.5 pounds supports a wide variety of exercises and progression.
    • Quick-adjustment dials make changing loads easier than handling separate plates.
    • Storage trays help keep the adjustable unit and plates organized.
    • Non-slip ergonomic handle and locking system support controlled use.

    Cons:

    • The 52.5-pound maximum may not be enough for advanced lifters.
    • The listing describes one dumbbell, so balanced two-arm work requires a second unit.
    • JRNY access lasts only two months, limiting the ongoing value of the included digital access.

    Best for: Home lifters who want a broad 5–52.5-pound range in one adjustable dumbbell and have limited space for fixed weights.

    Not ideal for: People who need a matched pair in one purchase, require loads above 52.5 pounds, or prefer the simplicity of a fixed dumbbell.

    • Weight range:5–52.5 lb
    • Quantity:1 dumbbell
    • Item weight:55 lb
    • Dimensions:16.9 × 8.3 in (L × W)
    • Materials:ABS, alloy steel, plastic, polypropylene, rubber
    • Handle material:Alloy steel
    • Special features:Adjustable weight, non-slip handle, locking system
    • Included:Storage trays
    • Model:BFW0023-OS
    Our verdict

    “Choose the SelectTech 552 if you want one space-saving adjustable dumbbell with more progression room than the 25-pound Amazon Basics model.”

11. Marcy 3 lb Neoprene Dumbbell, Single

    

    Best for Light-Toning Workouts

    View Latest Price

    The 3-pound cast-iron core gives this single dumbbell more substance than a very light hand weight, while the textured neoprene covering offers a comfortable grip for controlled arm exercises. Its no-roll head helps keep it from wandering between sets, and the rust-resistant finish suits regular home use. Compared with the Marcy 1 lb Neoprene Dumbbell, this is the more useful choice when a little extra resistance is welcome; it is still far lighter than the Amazon Basics 10-Pound Rubber Hex Dumbbell, so it is not a substitute for heavier strength work. The tradeoff is its narrow use range: experienced lifters may outgrow 3 pounds quickly, and the listing is for one dumbbell, not a matched pair.

    Pros:

    • Textured neoprene coating supports a secure grip during controlled movements.
    • No-roll head helps keep it in place between exercises.
    • Rust-resistant finish suits home workout storage.
    • Three pounds offers more resistance than the Marcy 1 lb Neoprene Dumbbell.

    Cons:

    • A single dumbbell means a matched pair requires buying another unit.
    • Three pounds may not provide enough resistance for experienced lifters or heavier exercises.

    Best for: Beginners and home exercisers who want a light, grippy weight for arm exercises, mobility work, or gradual resistance training.

    Not ideal for: People building strength with heavier lifts or shoppers who need a pair in one purchase; 3 pounds may be too light for progression, and this is sold individually.

    • Weight:3 lb
    • Quantity:1 dumbbell
    • Core and coating:Cast iron with neoprene coating
    • Handle material:Neoprene
    • Features:Non-slip, no-roll head, rust resistant
    • Dimensions:6 × 2.6 in
    • Color:Strawberry
    Our verdict

    “Choose this single 3-pound weight for light home workouts when you want more resistance than a 1-pound option without moving up to a heavy rubber hex dumbbell.”

12. Amazon Basics 10-Pound Rubber Hex Dumbbell

    

    Best for General Strength Training

    View Latest Price

    This single 10-pound rubber hex dumbbell is the lineup’s practical middle ground between the light Marcy neoprene weights and heavier fixed dumbbells such as the Amazon Basics Rubber Hex Dumbbell, 20 lb. Its solid cast-iron heads provide a straightforward fixed load, while the rubber encasing helps soften contact with floors. The hexagonal ends resist rolling, which is useful for home workouts that alternate lifting with floor exercises. A contoured, textured handle also gives the hand a more defined grip than the neoprene handles on Marcy’s lighter weights. The main limitation is that 10 pounds is one fixed weight: it may suit curls, presses, and similar movements, but cannot adapt as strength changes. It is also sold as one dumbbell, so paired exercises require a second purchase.

    Pros:

    • Ten-pound load suits a range of basic strength exercises.
    • Rubber-encased cast-iron heads help reduce hard contact with floors.
    • Hexagonal ends help prevent rolling during floor workouts.
    • Textured, contoured handle supports a secure grip.

    Cons:

    • Sold individually, so two-dumbbell exercises require purchasing another unit.
    • Fixed weight offers no way to increase or decrease resistance.
    • Heavier than the Marcy 3 lb Neoprene Dumbbell for light, high-repetition work.

    Best for: Home exercisers who want one moderate fixed weight for arm work and general strength exercises, with rubber-coated heads for floor-friendly storage.

    Not ideal for: Buyers who need a matched pair immediately, want a lighter weight for gentle toning, or need adjustable resistance for a changing program.

    • Weight:10 pounds
    • Material:Cast iron with rubber encasing
    • Handle material:Rubber
    • Handle diameter:1.07 inches

13. Marcy Classic Rubber Hex Dumbbell, Single Weight, 5–70 lb

    

    Best for Weight Progression

    View Latest Price

    Marcy’s Classic Rubber Hex Dumbbell stands out for its wide choice of fixed weights, from 5 to 70 pounds. That range makes it easier to select a suitable load now and move up later without changing dumbbell styles. The rubber-coated cast-iron heads help protect floors and reduce noise, while the diamond-knurled steel handle offers a firmer, more defined grip than the contoured rubber handle on the Amazon Basics 10-Pound Rubber Hex Dumbbell. Its hex shape also keeps it from rolling during floor exercises. The tradeoffs are practical: each weight is sold separately, so building a pair or a progression set takes multiple purchases, and the listing data does not identify the selected weight. It is a stronger fit for people choosing a specific load than for anyone expecting an adjustable dumbbell.

    Pros:

    • Weight options span 5 to 70 pounds for a broad range of strength levels.
    • Rubber coating helps protect floors and reduce noise.
    • Hexagonal heads resist rolling and support floor exercises.
    • Diamond-knurled alloy steel handle provides a secure grip.

    Cons:

    • Each dumbbell is sold individually, so pairs and weight progressions require separate purchases.
    • The selected weight is not specified in the supplied product data.
    • Fixed-weight design cannot replace an adjustable dumbbell for changing loads.

    Best for: Strength trainees who want to choose a fixed weight now and retain the option of buying heavier Marcy weights as their training advances.

    Not ideal for: Shoppers who want a pair or multiple resistance levels in a single purchase, or who need confirmation of the selected weight from the listing data.

    • Weight options:5, 8, 10, 12, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, and 70 lb
    • Unit count:1 dumbbell
    • Materials:Cast iron, rubber, alloy steel handle
    • Head shape:Hexagonal, anti-roll
    • Handle:Diamond-knurled grip
    • Dimensions:8.9 in L × 3.1 in W
    • Handle diameter:1.1 in
    • Color:Black/chrome
    • Model:IBRH-005
    Our verdict

    “Choose this Marcy model if you want a grippy rubber hex dumbbell with a broad range of weight options and are comfortable buying each weight separately.”

14. Marcy Neoprene Dumbbell, 1 lb, Single

    

    Best for Gentle Movement

    View Latest Price

    At 1 pound, this Marcy is the lightest option among the four products here, making it a purpose-built choice for gentle movement rather than conventional strength progression. Its cast-iron core adds structure, while the textured neoprene surface and non-slip handle are suited to controlled arm exercises. The no-roll design keeps the weight settled between movements, and the rust-resistant finish is useful for home storage. Compared with the Marcy 3 lb Neoprene Dumbbell, this one asks less of the user and may feel more manageable for mobility routines or very light resistance work. That same low load limits its usefulness for building strength, and the unit is sold singly; buyers who want balanced two-arm exercise need to purchase a second dumbbell.

    Pros:

    • One-pound load suits gentle movements and very light resistance work.
    • Textured neoprene handle offers a non-slip grip.
    • No-roll head helps keep it in place between exercises.
    • Rust-resistant construction supports home storage.

    Cons:

    • One pound is too light for many conventional strength exercises.
    • Sold as a single dumbbell, so paired movements require a second purchase.
    • Provides less resistance than the Marcy 3 lb Neoprene Dumbbell.

    Best for: People seeking a very light hand weight for gentle arm movements, mobility routines, or low-resistance home exercise.

    Not ideal for: Buyers aiming to build strength with progressively challenging loads, or anyone who wants a pair without buying two separate units.

    • Weight:1 lb
    • Quantity:1 dumbbell
    • Materials:Cast iron, neoprene
    • Handle material:Neoprene
    • Handle diameter:1 inch
    • Dimensions:5 × 2 inches
    • Grip size:Medium
    • Features:Non-slip, no-roll head, rust-resistant
    • Model:INE-001
    Our verdict

    “Choose this single 1-pound dumbbell for gentle, low-resistance movement, but select the 3-pound Marcy instead if you want more challenge from a similarly compact neoprene weight.”

How We Picked

I ranked these single dumbbells by how well each type serves a clear buyer need: a versatile fixed weight, light training, broad load progression, or limited storage. I weighed practical details such as weight range, grip and coating style, stability for common movements, ease of storage, and the maintenance demands of fixed versus adjustable designs. Since the list includes both individual weights and adjustable units, I judged each against its intended use rather than treating every model as a direct substitute.

The ranking favors options that are useful to a wider range of home lifters and involve fewer compromises for their role. The Amazon Basics 20-pound hex weight leads as a practical fixed-weight choice; Marcy’s lighter neoprene singles rank as targeted picks rather than general strength tools. Adjustable models earn their place for space-conscious buyers, but their added hardware means they do not automatically outrank simple fixed weights. I also account for the difference between buying one dumbbell and buying enough weights to support balanced training.

Factors to Consider When Choosing Best Single Dumbbells

Choosing a single dumbbell is not just a matter of picking a weight. I would match the purchase to the exercises you plan to do, how you expect your strength to change, and whether one-sided training is intentional or simply a first step toward a pair.

Choose a Weight for the Exercises You Will Actually Do

A weight that works for curls may be too light for rows, presses, or lower-body movements, so start by listing your main exercises. For a single dumbbell routine, some movements use one weight held with both hands, while others are performed one side at a time. Think about the weakest movement in your planned routine, not only the exercise where you can lift the most. Beginners often buy too heavy because they focus on strength exercises and overlook control during raises or rehabilitation-style movements. If you expect to train several muscle groups, an adjustable model or a weight that supports your main compound exercises may serve longer than a narrowly chosen light dumbbell. For a focused accessory routine, a lighter fixed weight can be easier to handle and less complicated.

Decide Whether One Dumbbell or a Pair Fits Your Routine

A single dumbbell works well for unilateral exercises, carries, and movements where one weight is held in both hands. It may limit exercises that require matching loads in both hands, including many presses, curls, and rows performed together. Before buying, check whether your planned routine alternates sides or expects simultaneous two-arm work. Starting with one weight can be a sensible way to test a training style, but adding a second matching dumbbell later may be difficult if a model or finish changes. If balanced two-sided workouts are the goal, compare the cost and storage of a pair against the convenience of an adjustable option. The right choice depends on programming, not just the number of dumbbells on the shelf.

Fixed Weight or Adjustable: Trade Simplicity for Range

Fixed dumbbells have a set load and no selector system, which keeps setup simple and makes the weight immediately ready for a set. Adjustable dumbbells bundle several loads into one unit, making them attractive when floor space is limited or when workouts call for frequent weight changes. That space saving comes with more parts to handle and a base or storage tray that needs a stable place. A single adjustable dumbbell also does not provide two matching weights for simultaneous exercises. Consider how often you change loads, whether other household members will use it, and whether you prefer a familiar fixed handle. Buying for occasional, same-weight workouts often favors a fixed dumbbell; varied programs and tight storage may favor adjustable.

Match the Coating and Shape to Your Home

Rubber-coated hex dumbbells and neoprene-coated weights address different practical needs. A hex shape can help limit rolling when the dumbbell is set down, which is handy in small workout areas, while a softer coating can be appealing for lighter home exercises. Neither coating makes a dumbbell immune to wear or impact, so avoid dropping weights and keep them off delicate flooring. Also check how much room the handle and heads occupy, especially if you plan to store several weights together. A compact single weight is easier to tuck away than a full rack, but several individual loads can quickly take more space than expected. Choose a finish that fits your storage and floor-care habits, not just its appearance.

Plan for Progression Before Buying a Very Light Weight

Light dumbbells can be appropriate for controlled accessory work, early-stage training, or movements where heavier loads compromise form. They may become limiting quickly if your strength improves or if you want to use the same weight for rows and presses. Before selecting a very light single, decide whether it is meant for one specific movement or a wider routine. Small weight increments can help make progression more gradual, but a single dumbbell does not provide a complete progression path on its own. Buyers who anticipate moving up should check whether matching weights in other increments are available in the same product family. That can reduce the chance of ending up with a mismatched collection that is harder to use as a set.

Factor Maintenance and Long-Term Use Into the Choice

Fixed weights have little setup, but they still need a dry storage spot and occasional checks for coating damage or loose components. Adjustable designs call for more careful handling because selectors and trays are part of their operation; follow the maker’s instructions and avoid using them outside their intended setup. If a dumbbell will be shared, consider whether everyone can select and return its weight correctly. A single dumbbell also sees repeated contact with the same hand, so handle comfort matters during longer sets as much as it does during a quick lift. Buyers seeking a low-fuss option may prefer a fixed weight, while those prioritizing fewer pieces of equipment may accept extra care for an adjustable unit. The best long-term fit is the one your household can store and use consistently.

Frequently Asked Questions

Is one dumbbell enough for a balanced home workout?

One dumbbell can support unilateral rows, carries, lunges, and exercises where you hold a single weight with both hands. It is less suited to movements that call for equal loads in both hands at the same time. You can still train both sides by alternating them, though this may lengthen a workout. If your plan includes paired presses or curls, check whether you are willing to buy a second matching dumbbell later. A single weight is a useful starting point, but it does not replace a pair for every training style.

Should I choose a fixed dumbbell or an adjustable one if I have little storage space?

An adjustable dumbbell can replace several fixed weights and may suit a small workout area, especially if your routine uses a range of loads. It also needs a stable place for its base, and selector hardware calls for careful handling. A fixed dumbbell is simpler to pick up and put away, but collecting multiple fixed weights can take more room. Remember that one adjustable unit still does not give you a pair for two-handed, simultaneous exercises. Choose based on both storage footprint and how your workouts use weight changes.

What weight should I buy if I am new to strength training?

There is no single beginner weight that fits every exercise or person. Select a load that lets you complete controlled repetitions without swinging or losing form, then account for the fact that rows and presses may call for more weight than raises. The Marcy neoprene singles in this roundup cover light loads, while the Amazon Basics hex weights suit buyers who need a heavier fixed option. If you want one dumbbell for several types of exercise, choose around your main strength movements rather than the lightest exercise alone. When unsure, a suitable light weight for a specific movement is more useful than a heavier one you cannot control.

Can I use a single dumbbell for exercises that normally use two?

Many two-dumbbell exercises can be adapted by working one side at a time, provided the movement remains stable and controlled. This approach can make one dumbbell useful for rows, presses, and curls, though you will need to repeat the set on the other side. It may also change the exercise’s balance demands, so start with a manageable load and sound technique. Some movements rely on holding equal weights in both hands, and a single dumbbell will not reproduce them exactly. If those exercises are central to your plan, a matching pair or a second unit should be part of your equipment plan.

When is a light neoprene dumbbell a better choice than a rubber hex weight?

A light neoprene weight makes sense when you need a small load for controlled raises, high-repetition movements, or a beginner routine that emphasizes movement quality. It is a focused tool, not a substitute for a heavier dumbbell when your program includes rows, presses, or loaded lower-body exercises. The rubber hex weights in this roundup offer heavier fixed loads and a shape that can resist rolling when set down. Think about the exercises and training stage first, then choose the coating and weight that suit them. If you expect to progress quickly, check whether you can add compatible weights rather than relying on one light single indefinitely.

Conclusion

For most buyers seeking one useful fixed weight, I would start with the Amazon Basics Rubber Hex Dumbbell, 20 lb: it is the roundup’s best overall pick for a range of common strength exercises. For value-minded shoppers, the Amazon Basics 10-, 15-, 20-, and 25-pound hex options provide straightforward fixed-weight choices, with the best fit depending on your training load. For beginners or light exercise needs, Marcy’s neoprene singles stand out because the lineup includes small weights from 1 to 10 pounds. For buyers who want a broader load range in less space, the BowFlex SelectTech 552 is the premium adjustable choice, while the Amazon Basics adjustable model is another space-conscious alternative. If you want a heavier fixed-weight collection, look at Marcy’s Hammertone or Classic Rubber Hex range; if your main need is one specific light exercise, choose the neoprene weight that matches it. The best choice is the one that fits your actual exercises and leaves room for the way you plan to progress.
