Our MSD-Band is a premium quality, low powder latex resistive exercise band. Using the MSD-Band for resistive exercise provides positive as well as negative force on the muscles and improves the range of motion, the strength and the cooperation of the muscle groups. The different resistance levels are determined by the thickness of the band. Our 45.5m roll represents the best value we have to offer.
