Our research-proven training methods and equipment were specifically developed with the objective of providing a safer and more effective way of loading and exercising muscles. By simply slowing the speed of movement while lifting weight, it creates more tension in a muscle. And physiologically, lifting more slowly and deliberately activates a greater number of muscle fibers for a given movement. The result provides more strength development in a shorter period of time with greater safety and much better efficiency. In fact, the results of slow-protocol resistance training ca n virtually eliminate the need for aerobics or other excessive cardiovascular or injury-inflicting exercises.
