Adjustable dumbbells replace a rack of fixed pairs with one compact set. They are a big purchase, so a few minutes of comparison is worth it.
Weight range
Check the lowest and highest weight per dumbbell. Many beginners outgrow a set that tops out at 25 lb in a few months, especially for squats and rows. If you can afford it, pick a set that goes to at least 50 lb per hand. If you are very new or train with light weights, a smaller set can be fine.
Weight increments
Look at how big each jump is. Two and a half to five pounds is typical. Large jumps make it harder to progress smoothly, especially on presses where a 10 lb jump is a lot.
How the weight changes
- Dial systems let you turn a dial and lift. They are fast between sets.
- Pin or selector systems use a pin or lever, which is quick and sturdy.
- Collar and plate systems are the cheapest but slow to change and can rattle.
If you do supersets or circuits, a fast adjustment system saves a lot of time.
Handle and balance
Hold the handle if you can. A good handle has a firm grip without being sharp, and the weight should feel balanced without wobbling. Larger plates can bump into your thighs on some exercises, so check the shape.
Footprint and storage
Measure your space. Most sets come with a tray or stand, which takes floor space. If you have a small room, see our guide to small apartment workout equipment.
Build and warranty
- Read about the cradle material. Plastic cradles can crack, while metal or thick reinforced plastic lasts longer.
- Check the warranty length and who handles claims.
- Look at the return policy so that you can send the set back if the handles do not suit you.
When fixed dumbbells are better
If you only need one or two weights, a fixed pair can be cheaper and simpler. Adjustables shine when you want many weights in a small space.
