This lesson focuses on improving acceleration mechanics through wall drills and sled push exercises. The wall drill emphasizes proper posture, hip projection, and triple extension, with variations like one-step and three-step drills. The sled push progression helps athletes develop the feeling of optimal body position, starting with a slow march and progressing to high-intensity pushes. Key points include maintaining a strong shin angle, keeping the hips forward, and sweeping the track to enhance forward propulsion. This drill set bridges the gap from wall drills to race-ready acceleration form.
