4 reasons I use chain resisted sprints to train the 40 yard dash?

1️⃣ Teaches horizontal force production
Forces athletes to push the turf instead of spinning their wheels.

2️⃣ Reinforces proper shin & body angles
Chains punish early pop-up and reward correct drive-phase positions.

3️⃣ Self-regulating resistance
Light early, heavier as velocity increases-matches true acceleration demands.

4️⃣ Improves first-step & 0–10 efficiency
Targets the most important part of the 40: the start and projection phase
