Features:

Exercise with powerball is completely equidistant, so it can complement any training method. Powerball exercises the arms in a way that conventional isotonic (free weight) exercise training cannot achieve, and it can absorb a higher percentage of muscle fibers in a shorter time. If you want to improve your wrist, grip and arm strength, then the wrist training ball will be your perfect choice!

Introduction:
*Strong Power
The maximum possible rotation speed exceeds 12,000 rpm, which can generate resistance of up to 32kg. It is the ultimate product of wrist exercise equipment-slow rotation for gentle rehabilitation, or fast rotation for forearm exercises for no more than 60 seconds.

*Good Trainer
Whether playing drums, piano, saxophone or guitar, musicians need to maintain strength, coordination and dexterity in their fingers and hands. Powerball helps to improve agility, speed, accuracy and endurance-if you can make music, Powerball will help you play better.
