Your question was: Why does my Hand Exerciser get sticky?
Our experts said: The yellow and red hand exercisers are designed specifically for individuals with weak grip strength, or post-operative patients. The most common mistake is using the yellow Hand Exerciser for patients with high grip strength. The high grip forces cause the exerciser to "break down" prematurely, breaking the membrane around the exerciser. First clean the hand exerciser with warm soap and water, then apply corn starch. If this doesn't help the problem, replace your hand exerciser with a higher resistance.
