Phase-by-phase break
Your long jump broken into the phases coaches grade. AI tells you which phase is costing you the most and why.
Long Jump form check on demand. Upload a clip of your long jump and AI flags every break in technique with priority tags, what's critical, what's minor, plus the drill that fixes each one. The same form-check feedback you'd post for online, private and immediate.
Your long jump broken into the phases coaches grade. AI tells you which phase is costing you the most and why.
When a coach says "your form is off," you don't always know where. AI marks the exact frame the error appears, with a coaching note attached.
Every flagged error comes with the drill that targets it. No generic homework, no guessing what to work on next session.
You'll see priority-tagged technique notes, the specific frames where the form breaks, and the drill that targets each issue. It's a full long jump form check in under a minute, the kind you'd pay an expensive remote coach for.
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.
Each phase has a coaching cue, a measurable target, the frames a coach pauses on, and the failure mode AI flags most often. Use it as a self-diagnostic checklist on every video.
14-22 strides building from drive to controllable max velocity. Speed at the board is the single biggest predictor of jump distance (r=0.86 vs distance in elite women).
Second-to-last step lowers the CoM ~9 cm to load for the takeoff drive. The penultimate step is 12.2% longer than the last step in elite jumpers.
Foot grounded on the board with active strike (not a reach). Free leg drives knee high; arms swing up. The optimum takeoff angle is ~21 deg for elite men.
Hang: body extended, arms up. Hitchkick: cycling motion (1-2 cycles). Sail: simplest, both legs forward (HS-level). Choice depends on hang time and skill.
Heel lands first, ahead of CoM. Hips slide past the heels (no fall back).
