Improve your running speed with the Sprinter Workout. The routine can be done indoors as well as outdoors (High Skips & Straight-Leg Bounds). Sprinting is broken down into three stages: explosion, acceleration, deceleration. In terms of the 100m sprint distance you are looking at a 20/25m-50m-25/30m segmentation. The principle holds true whether you're running 200m or 400m or the emotionally difficult 800m sprint. The Sprinter workout is designed to help you develop the muscle power necessary to carry you through each of those segments.
Extra Credit: 1 minute rest between sets.
