As age grows myofibrillars are loose and fragile because of pregency, fataccumulation, lack of exercises and other factors. People become fatter andflabbier. The equipment interacts with muscle neurons to induce supra-maximal muscle contractions. In the process of continuous musclecontractions, part of myofibrillar are gradually broken to cause muscle self-repair. After treatment, myofibrillars tend to be strong and tight, musclebecomes firm and elastic. It responds with a deep remodeling of innerstructure that result in muscle building and growth and body shaping.
