Golds Gym Power Twister Wrist Exerciser allows you to combine your strength training and aerobic training into one workout. Power Twister is like the old spring-coiled bar, but even better. It uses an adjustable spring-tension mechanism, to work on your arms, shoulders, back, chest and grip; it’s perfect for building upper-body strength.

Built from durable, chrome-plated steel and available in moderate and heavy resistance, the Power Twister does not need any added weight: you simply twist the resistance level up or down. And textured, grippy rubber handles ensure your workout is a comfortable one.
