The strong adhesiveness of the Power Tape patches means that they last and perform well even during rigorous activity or exercise. The Carbonized Titanium coating encourages muscles to relax and can be used on specific areas to relieve muscle tension or strain, aid injury prevention, and provide relief from discomfort in the knees, elbow or lower back. Also provides instant relief for tension in neck or shoulders. Apply before exercise to help prevent cramping or after to assist recovery. This pack contains 70 small discs.
