Snap, don't kick
The lead leg should snap up off the trail leg's drive, not be lifted by the hip flexors. Kick-style lead legs are slow and high. AI flags lead-leg height vs forward velocity tradeoff.
The lead leg in hurdles is what makes the clearance fast. Snap up over the barrier, fully extended, knee high enough to clear cleanly. Recovery to the ground is just as important, foot strike active, ahead of the center of mass. Here's how to train lead leg specifically.
The lead leg should snap up off the trail leg's drive, not be lifted by the hip flexors. Kick-style lead legs are slow and high. AI flags lead-leg height vs forward velocity tradeoff.
Lead-leg knee should clear the barrier with minimal vertical waste, 2-4 inches above the bar. Higher than that, you're losing forward speed. AI measures clearance height.
Lead leg comes down active, foot striking ahead of the center of mass. Passive landings cost you stride pattern into the next barrier. Drills: lead-leg wall drills, stationary lead-leg snaps.
