Autostart Powerball Wrist Powe

Features:

BUILD GRIP & ARM STRENGTH – As you spin Powerball it generates resistance – the faster you spin, the stronger the resistance will be. Harness the immense power of Powerball at fast speeds to build solid upper arm muscles, a stronger wrist and the ultimate grip.
GREAT FOR REHABILITATION – At low speeds, Powerball is highly effective in injury rehab and pain relief. Weather it’s a wrist, hand, finger or forearm injury; or stiffness and discomfort in these joints – then Powerball is for you. Used by millions worldwide for injury prevention & recovery (carpal tunnel, tendonitis, breaks, sprains, etc).
100% ISOMETRIC EXERCISE – Powerball generates isometric resistance as you spin it. Isometric resistance engages a much higher percentage of muscle fibres than standard isotonic training (e.g. free weights) does. It is also non-impact, making it a form of strengthening that places ZERO strain on your muscles as you exercise.
ENHANCED SPORT & MUSICAL ABILITY – An effective exercise tool that will dramatically improve grip strength and finger dexterity, Powerball is a must-have product for all serious athletes (golf, tennis, climbing, boxing, etc.) and musicians (guitar, drums, piano).
