Gold's Gym Wrist Wraps Approximately 51cm in length 2 pieces Cotton (Nylon for the logo) By utilizing lifting straps, you can control heavier weights more effectively. There is a significant difference in the power that can be exerted by the large muscles of the back and the muscles of the fingers. It's a waste if your back muscles still have the strength to lift heavier weights, but your grip strength isn't keeping up, forcing you to settle for lighter weights. Using straps allows you to use heavier weights with better control. (From the HP) I have hardly used them, and I believe they are in good condition. I will ship anonymously. Thank you for looking.
