1 PAIR of CONTOURED HAND GRIPS

I opened the box and tried them out once for the experience, no other use. MEDIUM RESISTANCE as listed on box Increases HAND, WRIST & FOREARM Strength "No actual measured squeeze grip rating but from my experience it's fairly tough. I can see if you used it too much you may have muscle soreness pending your personal fitness level." Manufactured by CAP Barbell Inc.
