Strength jumping system  | | | | | | | | | | Strength created the concept of frontal platform shoes. In regular shoes, 70% of the body’s weight rests on the heel. Therefore, the calf muscles exert little effort in supporting the body. In Strength® Shoes, the heel is eliminated, causing the calves to support 100% of the body’s weight. This overload works the calves and Achilles tendons with a force equal to 6 times the body’s weight upon impact. As the force of impact occurs, the heel dips causing the achilles tendon to stretch. The Strength® System can also increase your anaerobic capacity and your anaerobic power by 500%. Each System includes: One pair of court shoes and a basic training video. |
