Cues, not corrections
"Drive your knee" beats "your knee was a little low." Cue-based coaching gets the change to happen in the next rep, not the next month. AI prescribes cues for what it sees, not just diagnostic notes.
Sprints tips are everywhere. Most are generic. Here are the cues real sprints coaches use, short, specific, and tied to the phase of the rep where they apply. Pair them with AI form check and you have a feedback loop that closes.
"Drive your knee" beats "your knee was a little low." Cue-based coaching gets the change to happen in the next rep, not the next month. AI prescribes cues for what it sees, not just diagnostic notes.
Most athletes try to fix three things at once and fix none. Pick one cue per rep, see what it does, then iterate. The AI surfaces the one cue that would close the biggest gap in your sprints.
A cue is only useful if it triggers in the right phase. "Heel down" means nothing without a moment to apply it. Each AI tip is timestamped to the phase of sprints it belongs to.
Generic tip lists are everywhere. Tips tied to your specific form errors are not. Upload a clip and AI returns the 1-3 cues that would change the most in your sprints, ranked by impact.
Follow up in chat and ask questions. The AI remembers your analysis and speaks the language of sprints 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.
Set position, drive angle, and the first 2 strides out of the blocks. World-class sprinters reach ~33% of their max velocity by block clearance, in only ~5% of total race time.
Forward body lean, longer ground-contact times, aggressive horizontal force. The 100m is built or lost in this phase.
Body angle rises smoothly from drive to upright. Stride length grows; ground contact shortens. Speed approaches max.
Top-end speed phase. Vertical force dominates; ground contact ~0.09-0.10 s. Elite peaks at ~11.2 m/s, around 6.27 s.
Holding form through 80-100m as ATP-PC stores deplete. The race is decided here in close finishes.
