PowerBalls are, quite literally, a revolution in wrist strengthening and rehabilitaion.

The 280Hz Classic features a military-grade polycarbonate shell and a cord-start rotor (string activation). At just the size of a tennis ball, the 280Hz Pro can spin at up to 18,000rpm (rotations per minute) and output a massive 16kg in resistance. 

Harness this resistance at fast speeds to build serious arm, wrist and grip strength.

At low speeds, Powerball 280Hz Classic is great for rehabilitation and pain relief. Soothe injuries, such as carpal tunnel, tendonitis, breaks, sprains, etc. and encourage muscle strength for a quicker recovery.

100% non-impact isometric resistance.

Cord-Start, Drop Resistant
