The M.V.P. (Maximum Vertical Potential) program takes a comprehensive approach to maximizing your vertical jump. Attaining your maximum vertical jump involves training your entire body and using the Core 4 concept. The M.V.P. Core 4 program includes flexibility, leg strength, power, and core strength. Each of these components plays an important role in maximizing how high you can jump. If you fail to train a certain area (like most of the other vertical jump programs on the market); you will never reach your vertical jump potential. Improving your vertical jump is more than having strong calf muscles or jumping off of boxes. You must attack the Core 4 to unleash the M.V.P. in you!
