Phase-by-phase break
Your high jump broken into the phases coaches grade. AI tells you which phase is costing you the most and why.
High Jump form check on demand. Upload a clip of your high 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 high 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 high jump form check in under a minute, the kind you'd pay an expensive remote coach for.

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 slow down in the last 2-3 strides instead of accelerating through the curve, flattening your takeoff.
Curve-running drills with a stopwatch, compare penultimate-step times across attempts to catch the deceleration.
Your takeoff foot lands within 2 feet of the uprights, cramping the clearance and causing the athlete to drift into the bar.
Extend the approach by a half-step and re-measure until the takeoff is 3-4 feet from the uprights.
You begin the flop arch before clearing the vertical of the bar, reducing peak clearance and risking a back-bar hit.
Bar-arch drills from a box, focus on initiating the arch at peak height, not ascent.
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.
