Why does my hurdler's technique fall apart by the fourth rep in a drill set?
It is rarely about the hurdle itself. More often the limiter is how much rest sits between one rep and the next.
The first three reps of a hurdle drill look clean: chest up, lead leg snapping down, rhythm even. By the fourth, the lead leg starts dropping late, the trail leg drags, and a coach who only watched that last rep would swear the athlete never learned the drill at all.
Two different kinds of tired
Hurdle technique leans on fast, local muscle, the hip flexors and glutes that snap the lead leg down and pull the trail leg through. That kind of fatigue shows up well before an athlete is out of breath. A hurdler can have plenty of cardio left and still lose the lead-leg snap on rep four, because the muscles doing the fine technical work tired out long before the lungs did.
What this usually means for the rest, not the reps
- Shorten the set before loosening the standard. Four clean reps beat eight reps where only the first three count.
- Give full recovery between reps rather than a fixed, short interval. A technical hurdle rep is not a conditioning rep, and it does not need to feel hard to be worth doing.
- Stop the set at the first rep that breaks down, rather than running through it to hit a number decided before the session started.
The Workout page's reps-with-rest mode already times both halves of this, the rep and the rest before it, on the same phone that is at the drill. Reading the rest column back after the session is often the fastest way to see whether rep four broke down because the rest before it was actually shorter than the rest before rep two.
What the Film Room adds
Filming rep one and rep four under the hurdles setting and comparing trunk dip and lead-leg extension turns a hunch into a number: exactly how much further the trunk dipped, exactly how much the lead leg shortened, between the rep that looked fine and the one that did not.
A camera cannot tell you whether a breakdown is fatigue catching up with the athlete, or a fault that was there all along and only showed once the athlete stopped concentrating hard enough to mask it. Both look identical on the clip. Telling them apart is still a coach watching the whole set, not a single number from one rep.
