Most lost long 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 long 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 long 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.
You overstride at the takeoff board to 'hit' it, landing heel-first and creating a braking force that kills takeoff speed.
Approach-accuracy drills from a short-run start, focus on running through the board rather than reaching for it.
Your drive knee doesn't punch up at takeoff, flattening the jump and cutting distance.
Single-leg bounding and low-box jumps with a high knee-drive focus.
You collapse your torso forward mid-flight, landing early and short.
Hang-position drills on a high bar, focus on staying tall and extended through peak.
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.
Stride consistency, full-speed approach without aiming.
Full approach down the runway, no takeoff. Mark every takeoff foot landing.
Decelerating into the board; drift.
Long-low penultimate, quick last step.
From a 4-step approach, exaggerate penultimate depth and last-step quickness. Land on the board.
Penultimate same height as other steps.
Vertical drive, free-knee swing.
From a 2-3 stride approach, pop up off the board with maximum vertical lift. No bar, no distance goal.
Forward jump instead of vertical.
Takeoff + flight at low complexity.
From 4-6 strides, full jump with target landing.
Reaching at the board.
Body extension and hang position.
Hang from a high bar in extended position, hold 5 sec.
Bending at the hips (collapsing).
Cycling motion in flight.
From a 6-step jump, focus only on 1.5 cycles in the air. Distance is secondary.
Cycling too late; insufficient peak height.
