Most lost triple jump 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 triple jump 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 triple jump 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 hop is 38%+ of total distance, depleting the energy you need for the step and jump.
Short-run triple-jump drills from a 6-step approach, constraining the hop length with a taped target.
Your step phase is a landing rather than an active drive, killing horizontal momentum before the jump.
Step-phase bounding drills with emphasis on a knee-drive cue off the ground contact.
Your final takeoff knee gives way instead of punching up, flattening the jump phase.
Single-leg box jumps and heavy-single-leg strength work.
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.
