Drive-phase and posture work
Wall drills put your body in the same lean and knee-drive pattern as the first 10 meters of a sprint, without needing a track at all. Hands on a wall, body angled around 45 degrees, drive one knee up at a time for 10 contacts per leg, three sets. A-skips do similar work moving forward over 20 to 30 meters, and both drills transfer directly to drive-phase mechanics once you're back on the track and actually sprinting at full effort.
