3 Sec Weight Adjustment Dumbbells’ compact design replaces an entire set of dumbbells, hence saving a tremendous amount of space in your home. The locking mechanism sets it apart from other adjustable dumbbells by locking in properly positioned weight plates so they won't separate from the handle. The sleek, smooth design enhances your workout area.
Covered with a unique injection-molded plastic, 3 Sec Weight Adjustment Dumbbells won't clank and clatter when they are set down. The cover also keeps weights from scratching floors or other surfaces they might touch. And no matter how sweaty the workout gets, they are protected from corrosive rust.
3 Sec Weight Adjustment Dumbbells provides the unique option of offset weight selection. Offset weight selection involves using a different weight setting on one side of the dumbbell relative to the other, assisting in supination and pronation of the wrist and forearm. During offset weight selection, the combination of weight plates selected will not be the same on both sides of the dumbbell, so it must be returned to the base in the same orientation that it was removed.
