内容説明
After many years of experimentation and training with athletes of all ages, George Dintiman and Bob Ward have developed a "can't miss", Seven Step Model for speed improvement. The programme has been proven to shave up to 7/10 of a second off school and college athletes' 40-yard dash times in the U.S. To help anyone learn to sprint faster, the Sportspeed Seven Step Model includes 5 simple tests that locate weaknesses; exercises for finding one's speed potential; tools for evaluating progress; sample workouts for improving speed, endurance, and power; and a complete record-keeping system to chart progress.
