IsoTone is an innovative, light, and portable resistance fitness and strength training device that automatically adjusts its resistance based on the force applied, making it an ideal tool for training athletes and sportsmen in different sports. The level of workout loads varies depending on need: from casual to extreme where the athlete reaches a highly aerobic state within a few minutes of intense exercise. IsoTone’s portability allows athletes to engage at any level of aerobic and strength developing exercises in a gym or, importantly, everywhere outside of gym, anytime.
