Power UP your game to the next level!
Use the Wrist Trainer to increase strength of fingers, wrist, hand, forearms, biceps, triceps, ligament and shoulders.
It is small and portable, making it convenient to be used anytime and anywhere.
No starter cord or external battery powered aid needed! Using the Spinner to strengthen your wrist and arms easier than ever! The Roll ‘n Spin Spinner incorporates a pre-tensioner inside the gyroscope that allows for a simple roll back to spin up the gyro with enough momentum to get you started.
The Digital LCD Display Counter will keep track of how fast you’re spinning our Spinner, or how many revolutions you’ve been spinning it.
