Somewhere, right now, an athlete is apologizing for their hurdler — worried it looks lopsided, that one leg is "doing it right" and the other has given up. So let's put the most important sentence first: in a hurdler, the asymmetry IS the design. Front leg drives up straight; back leg bends behind. On purpose. A hurdler isn't a toe touch that came up short on one side — it's its own jump, with its own standards, and judged by them it can be as sharp as anything in your repertoire.
What a clean hurdler looks like
Three things define the shape at the peak.
The front leg: straight, high, driving up in front — knee locked, the whole line from hip to ankle reading as one clean stroke. This leg is the headline. Its height and straightness are what the jump is scored on, and because it's a SINGLE straight-leg lift, most athletes can get it impressively high — which is exactly why the hurdler is often the first jump that feels genuinely good.
The back leg: bent cleanly behind, knee pointing down or back depending on your program's style, folded with intention rather than trailing like an afterthought. "Bent on purpose" is the standard — a crisp fold reads as technique; a leg that merely dangles reads as forgotten.
The trunk: square and proud. This is the hurdler's sneaky difficulty. With the legs doing two different jobs, the torso gets pulled two different ways, and the common leaks are a twist toward the front leg or a chest that dips to meet it. The posture rule survives the asymmetry below it: chest tall, shoulders level and square to the front, eyes forward. The legs split their duties; the chest doesn't get to.
And beneath it all, the same engine as every jump: a patient set — arm swing, real sink, drive on one count — and a landing with feet together, knees soft, stuck and frozen.
One filming note: front-on shows the front leg's height and straightness and whether your shoulders stay square. That's the view to use when you want a read. Pick "Hurdler" as the skill and the label reaches both the coach writing your notes and the measuring side: on a declared hurdler the left-right match read is set aside rather than called a fault, because the asymmetry is the design. Skip the skill picker and the app falls back to classifying the shape in the frames themselves — it sets that read aside only when it recognises the hurdler's one-bent-one-straight legs, and when it can't tell the shape, the row is scored as if both legs were meant to match, so a low number there is worth checking against the freeze-frame before you believe it. Film side-on and the question doesn't arise: the left-right match is a front-on read, so from the side it isn't measured at all and that row comes back blank.
The drill — Standing Kick Series
The hurdler's headline — a straight leg driven high off a proud chest — is rehearsed on the ground, one kick at a time. One hand lightly on a wall: kick straight to the front, knee locked, chest tall, then to each corner. For hurdler work, the front kicks with your lead leg are the money reps: that exact motion, straight and high without the chest dipping, is the jump's entire scoring line practiced with the floor's help.
The rule that keeps every rep honest: if your chest drops to buy kick height, the kick doesn't count. Height purchased with posture is a loan the jump has to repay at the peak.
Do 10 kicks each direction, each leg — yes, both legs, because a strong off-side kick keeps your body balanced and your options open.
Then throw hurdlers proudly. One leg straight and climbing, one folded clean behind, chest square and tall over both. Nothing about that needs an apology — it just needs reps.
