A-skip into B-skip, the full sprint-mechanic combo.

Keep the rhythm crisp and the foot pawing back under your hips, not reaching out front.
AB skips chain the two classic sprint drills together, the high knee A skip and the extend and paw B skip, all bounced off the balls of your feet. Your calves are the springs here, absorbing and returning force on every ground contact while keeping the ankle stiff. It is rhythm, elasticity and sprint mechanics packed into one moving drill.
An A skip drives the knee up and puts the foot straight back down. The B skip adds a leg extension at the top, then paws the foot back underneath you. This drill alternates the two so you rehearse both halves of sprint mechanics.
Before sprints, leg day or any explosive session. They wake up the calves and ankles, groove sprint rhythm and raise your heart rate without draining you. They are a drill, not a finisher.
You are reaching instead of pawing. The foot should strike underneath your hips, pulling back as it lands. Slow the drill down, shrink your forward travel and make the rhythm crisp before adding speed.
