Muscle tone is responsible for having the lean and well-toned body desired by everyone, as it supports tightly the above lying structures but it declines due to the inescapable aging and/or physical inactivity. When tone is lost and muscles lengthen, sagginess appears, especially in arms, belly and buttocks.

ZEROGYM mimics the effect of endurance training to improve the muscle tone even on sedentary lifestyle or with lack of time to exercise.
