The Healthy You Latex Free Resistance Bands were created for physical therapy and rehabilitation to improve strength, range of motion, or flexibility. They are manufactured to be molecularly similar to latex but protein/allergen free. Our unique latex free material stretches and feels just like latex band. It also has a higher tear strength and more proportionate resistance compared to TPE resistance bands. The Level Up System includes 5 levels of resistance. Level 1 is the least resistive and each level increases in steps to the highest resistance Level 5. Designed for clinical use with bulk rolls in a dispenser box that are easy to cut to a desired length or precut patient packs. Like all Healthy You Brand products the professional level quality ensures they can withstand heavy duty clinical use but are also perfect for at home treatments.
