Perfect form in high jump isn't about looking smooth. It's about hitting the targets coaches measure, phase by phase. Here's what perfect high jump form looks like at each phase, what coaches grade for, and how the AI compares your form to the standard frame by frame.
Each phase of high jump has a target. Takeoff angle. Body lean. Foot strike. Release height. "Perfect" means hitting the target on each phase, in order. The AI grades against the targets, not against how the rep looks.
A frame can look ugly and still work. A clean-looking frame can still cost you. The AI grades the mechanics, not the look. You stop chasing pretty form and start chasing the targets that matter.
Don't compare yourself to a pro's highlight reel. Compare your phase 2 to the standard for phase 2. The AI does this for you and tells you the gap, frame by frame.
Upload a clip, AI grades each phase against the form standard, and tells you the specific gap to close. Not a vague "work on your technique," a concrete read on which target you're under and by how much.
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.
The numbers coaches grade against. Levels run from beginner through elite, your AI form check compares your reps to the level above you.
