Phase by phase, not gut feel
Good high 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.
High Jump technique is about precision. Every high 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 high 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 high 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.
First 4-6 strides straight at the bar; final 4-5 strides curve in to generate centripetal force and inward lean. The Fosbury flop's optimal speed is not all-out; it's controllable speed.
Second-to-last step lowers the center of mass to load for vertical drive. Knee flexion happens here.
Drive leg plants ahead of CoM, free leg swings up, arms drive overhead. Lean rotates from inward to vertical to outward (away from bar).
Body rotates in flight: inward lean -> vertical -> outward arch over the bar. Arch is initiated by hip-thrust at peak height.
Pike-cup-snake-smile. Lead leg up first, hips through, trailing leg snakes over.
Lands on upper back / shoulders in pit. Controlled fall; the pit absorbs the impact.
