Applying the full potential of the X-Force operating principle reveals several benefits. For example, research shows that a properly trained muscle takes from 48 to 92 hours to recuperate and be ready for another bout. The stronger you are and the more intense your workout is, the greater the need for rest. Our predictions indicate that a highly motivated person will require a rest period of ten days in order to recover completely! 
The case for X-Force is strengthened 1) by the fact that training with this system also helps regenerate passive tissues (bone, cartilage, ligaments and tendons) and 2) by the way it accelerates recovery from injuries. 
Invented and developed by renowned Nautilus gym chain owner Mats Thulin, the X-Force machine has finally made Arthur Jone’s and the muscle research physiologists’ dream come true!
