Speed drills are super physique builders. Sprinting helps tone all legs muscles as well as the glutes and do a good job burning fat. Three different speed training drills are used for the program; skipping, striding and wind sprints. Skipping adds explosiveness to one's step and helps increase stride length. Top speed is obtained through a combination of optimal stride interval (leg quickness) and stride length. Striding, running at fifty to sixty percent of maximum speed, helps improve speed endurance. Speed-endurance is the ability to maintain top speed for a longer distance. Wind sprints develop acceleration and top speed.
