POWER PUTTY – The most effective hand strengthener because it works all the muscles of the hand in flex and extension – and it’s fun to use!
Power Putty is a unique flexible silicone rubber that can be squeezed, stretched, and pulled to do various exercises for strengthening and healing all the muscles in the fingers and hands.
MADE IN THE USA since 1977.
Other hand exercisers like springs and balls only work muscles that close the hand. Power Putty strengthens the extensor muscles that open the fingers and hands to develop strong, quick hands and improve dexterity, flexibility, and endurance.
