Learning how to adjust Bowflex adjustable dumbbells takes about a minute once you know the sequence. You will set a new weight, confirm the selector has locked into place, and check that the dumbbell is safe to lift. The steps below apply to the common dial-style Bowflex models, though exact details vary by model.
Before You Start
Never change the weight while the dumbbell is loaded in your hand or resting on a surface that could tip. Set the dumbbell on a flat floor, away from your feet. Check that the dial or selector area is clear of dust and debris, since grit can stop the plates from seating.

How to Adjust the Weight Step by Step
- Place the dumbbell on the floor and make sure it is stable.
- Grip the dial or selector handle and lift it slightly to release the tension on the locking mechanism.
- Turn the dial until the window or indicator shows your target weight. Rotate in one smooth motion instead of forcing it.
- Lower the dial back into its locked position. You should feel it click or seat firmly.
- Pick up the dumbbell and give it a light tug. If any plates shift or the dial rises, reset it.
Confirming the Selector Is Locked
A partially engaged selector is the most common cause of unexpected weight changes mid-set. Look at the indicator window and make sure the number matches your target. Then press the dial gently downward. If it moves, it has not fully engaged, and you should repeat step 4.
Adjusting Multiple Dumbbells Consistently
If you own a pair, set both dumbbells to the same weight before training. Mismatched settings can throw off your balance on single-arm exercises like rows and presses. Check each indicator window side by side.
| Check | What It Confirms |
|---|---|
| Indicator window | Target weight is displayed |
| Dial press test | Selector is fully seated |
| Matching pair | Both dumbbells show the same setting |
Common Mistakes to Avoid
- Turning the dial while the dumbbell is in the cradle without lifting the handle first.
- Skipping the post-adjustment tug test, which catches loose plates early.
- Forcing the dial past its stop. Resistance usually means the selector is misaligned.
- Adjusting weight on an uneven or carpeted surface where the cradle can wobble.
- Ignoring a dial that will not lock. Stop using the dumbbell until it is inspected.

Recommended Gear
A stable, level surface makes weight changes faster and safer. A rubber mat also protects the floor and keeps the cradle from sliding during adjustments.
- Rubber gym flooring tiles: they keep the cradle from shifting and protect your floor. View on Amazon
- Compact dumbbell storage rack: it keeps the adjustable dumbbells at a consistent height so you can reach the dial without bending awkwardly. View on Amazon
FAQ
Can I adjust Bowflex dumbbells while holding them?
No. Set the dumbbell on the floor first, then change the weight. Adjusting while holding it can cause the selector to slip and the weight to shift unexpectedly.
Why does the dial feel stiff?
Stiffness often comes from dust or debris in the selector area, or from not lifting the handle before turning. Clean the area gently and try again with the proper lift-and-turn motion.
How do I know the weight is set correctly?
Check that the indicator window shows your target number and that the dial does not move when pressed. A quick tug test after adjusting will also reveal any loose plates.
Conclusion
Adjusting Bowflex dumbbells is quick once you follow a consistent routine: set the dumbbell down, lift the handle, turn to your target weight, and confirm the lock. Make the same checks on both dumbbells every time. If the mechanism ever feels wrong or will not seat, stop and inspect it before lifting.
