Compared with the alternatives below, it saves the most space per pound and changes weight in seconds.
Best for: Most home gyms with limited space.

2. PowerBlock Elite EXP Stage 1 (5–50 lb) – Best Expandable Adjustable Dumbbells
- 5–50 lb per dumbbell, 16 settings

- ✗ Expansion kits cost extra
PowerBlock’s Elite EXP is the best choice if you might outgrow 50 lb. It starts at 5–50 lb and expands to 70 or 90 lb.
The block design is more compact than dial sets and very durable.
Best for: Lifters planning to get much stronger.
May not fit: Those who prefer a round dumbbell feel.
3. CAP Rubber Hex Dumbbell Set with Rack (150 lb) – Best Fixed Dumbbell Alternative
- Pairs of 5, 10, 15, 20 and 25 lb
- A-frame vertical rack included
- Rubber-coated hex heads
- Knurled steel handles
Pros
- ✓ Instant weight changes (just grab a pair)

- ✓ Very durable
Cons
- ✗ Takes more floor space
- ✗ Max 25 lb per hand
CAP’s rubber hex set gives you pairs of 5, 10, 15, 20 and 25 lb on a vertical rack. There is nothing to adjust, so you can move between weights instantly, and there is nothing to break.
The trade-off is space: five pairs and a rack take more room and still stop at 25 lb.
Best for: Families, group workouts and fast circuits.
May not fit: Small spaces or heavy lifting.
4. Amazon Basics Rubber Hex Dumbbell – Best Single Fixed Dumbbells
- Sold individually in many weights
- Cast iron with rubber-encased heads
- Hex shape prevents rolling
- Contoured, textured handle
Pros
- ✓ Extremely popular and affordable per pair
- ✓ Nothing to adjust or break
- ✓ Buy only the weights you need
Cons
- ✗ A full range gets expensive and bulky
- ✗ Needs a rack for storage
Amazon Basics rubber hex dumbbells are one of the most-rated fitness products on Amazon. You buy only the weights you need, one at a time.
For one or two favorite weights they are cheap, but building a full range costs more and takes more space than an adjustable set.
Best for: People who only need a couple of weights.
May not fit: Anyone building a full range.
5. CAP Cast Iron Spin-Lock Dumbbell Set – Best Plate-Loaded Alternative
- Up to 105 lb pair (other sizes available)
- 17″ knurled chrome handles
- Cast iron plates, star-lock collars
- Plates sold in 1.25–10 lb sizes
Pros
- ✓ Classic, durable design
- ✓ Expandable with more plates
- ✓ Good value per pound
Cons
- ✗ Slow to change plates
- ✗ Long handles
CAP’s spin-lock set uses threaded handles and cast iron plates. It is much cheaper per pound than adjustable dumbbells and lasts for years.
Changing weight means spinning collars on and off, so it is slow between sets.
Best for: Budget lifters who want heavy weight.
May not fit: Supersets and quick changes.
6. FEIERDUN DS2 5-in-1 Adjustable Dumbbell Set – Best Multi-Use Alternative
- Sets from 20 to 90 lb total
- Converts to barbell, kettlebell and push-up stands

- 15 mm foam on barbell connector
Pros
- ✓ Very versatile 5-in-1 design
- ✓ Huge review count
- ✓ Low price
Cons
- ✗ Slow to change plates
- ✗ Bulky plates
FEIERDUN’s DS2 converts from dumbbells into a barbell, kettlebell or push-up stands. It is the most versatile low-cost alternative.
Plates change slowly, and cement-free iron-sand plates are bulkier than dial sets.
Best for: Beginners who want variety on a budget.
May not fit: Serious strength training.
7. BowFlex SelectTech 840 Adjustable Kettlebell – Best Kettlebell Alternative
- 8–40 lb in 6 settings (8, 12, 20, 25, 35, 40 lb)

- Works with JRNY app (trial included)
Pros

- ✗ Not built for being dropped
If your workouts are mostly swings, goblet squats and conditioning, an adjustable kettlebell like BowFlex’s SelectTech 840 may suit you better than dumbbells. It dials from 8 to 40 lb.
Kettlebells are less ideal for curls and presses with both hands.
Best for: Conditioning and full-body circuits.
May not fit: Traditional bodybuilding moves.
Adjustable Dumbbells vs Alternatives: How They Compare
Adjustable vs Fixed Dumbbells
Adjustable dumbbells save a lot of space and cost less than a full fixed range. Fixed dumbbells are faster to switch, tougher and better for several people training at once.
Adjustable vs Spin-Lock Dumbbells
Spin-lock sets are cheaper per pound and nearly indestructible, but changing weight is slow. Adjustable dials change in seconds.
Adjustable vs Multi-Use Sets
5-in-1 sets like FEIERDUN add barbell and kettlebell modes at a low price, but they are bulky and slow to adjust.
Adjustable Dumbbells vs Kettlebells
Kettlebells excel at swings and conditioning; dumbbells are better for presses, curls and rows. See our best adjustable kettlebells guide.
Which Should You Choose?
Short on space: adjustable dumbbells. Many users or fast circuits: fixed set. Tight budget and heavy weight: spin-lock. Start with our best adjustable dumbbells guide if you choose adjustable.

What is the cheapest alternative to adjustable dumbbells?
Spin-lock dumbbell sets and multi-use 5-in-1 sets are usually the cheapest per pound.
