Most lost hurdles performance comes down to a small handful of mistakes. The same ones show up across HS, club, and college athletes. Each one has a clear look on video. Here are the ones the AI flags most often, with the fix for each.
Trail leg drop in hurdles. Takeoff under the top hand in pole vault. Reaching at the board in long jump. The same errors show up in athlete after athlete, and they look the same on video. The AI catches them in the same frame a coach would.
An error in phase 4 of hurdles usually has its root in phase 2. Fixing the symptom doesn't help. AI traces the chain so you fix the actual cause, not the visible effect.
Every flagged mistake comes with the drill that targets it specifically. No generic drill list, no busywork. The drill that fixes a takeoff issue isn't the drill that fixes a release issue.
Read about mistakes, then upload a clip and see if you have any of them. AI runs the same checks a coach would and tells you in plain language what's happening, plus what to do this week to fix it.
Follow up in chat and ask questions. The AI remembers your analysis and speaks the language of hurdles coaching.
Each fault below is described two ways: how it looks on video (so you can recognize it on your own clips) and the drill or cue that fixes it. AI form check identifies these patterns in the same frames a coach would.
Your takeoff foot lands closer than 6.5-7 feet from the hurdle, forcing a scraping clearance and loss of momentum.
Approach work with a taped takeoff mark, and lead-leg drills from a measured distance.
Your trail leg hits the ground before the lead leg has fully extended forward, killing the stride pattern into the next barrier.
Trail-leg wall drills and hold-the-hurdle drills to groove a late trail-leg drop.
Your torso is vertical over the hurdle instead of leaned forward, wasting vertical energy and losing distance over the barrier.
Attack-the-hurdle drills with the cue 'lead-leg to opposite elbow' to produce forward lean.
These drills come from coaching practice (Dahlman, Petrov-Bubka tradition, Slippery Rock camps). Each card lists the phase it targets, the method, what to watch for, and a prescribed rep volume.
Knee drive and snap of the lead leg.
Stand 1 ft from a wall. Drive lead-leg knee to the wall, snap foot out, return.
Locked-out leg; kicking instead of snapping.

Set hurdles at 5-step distance. Practice rhythm without speed pressure.
Counting wrong leg lead.
Quick lead-trail-lead-trail cycling.
Hurdles at low height, very close (3-4 m). Step over, alternating lead leg.
