Phase by phase, not gut feel
Good long jump technique isn't a vibe. It's a sequence. Each phase has clear targets you can measure: angles, foot positions, body lean. The AI tells you which phase in your rep is costing you the most.
Long Jump technique is about precision. Every long jump rep is a chain of phases. Each phase sets up the next. Get the phase-by-phase breakdown coaches use, plus AI that grades your own technique against it, frame by frame.

Watch a long jump coach review tape. They pause on the same handful of frames every time. The takeoff, the plant, the release, the clearance. The AI pulls those exact frames for you.
Most form errors trace back one or two phases. Fixing the symptom doesn't help. The AI traces the chain back to the cause so you fix the right thing.
Upload a clip, AI tags every phase, marks where technique breaks, and writes a coaching note for each one. The same phase-by-phase read your coach would give, but on every rep, not just meet day.
Follow up in chat and ask questions. The AI remembers your analysis and speaks the language of long jump coaching.
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).
The numbers coaches grade against. Levels run from beginner through elite, your AI form check compares your reps to the level above you.
