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.
Discus tips are everywhere. Most are generic. Here are the cues real discus 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 discus.
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 discus 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 discus, ranked by impact.
Follow up in chat and ask questions. The AI remembers your analysis and speaks the language of discus 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.
Discus rests on first joints of fingers, hand spread. Stand at the back of the circle, feet shoulder-width.
1-2 swings to load the throwing shoulder. Builds rhythm and torque.
Body rotates 1.75 turns across the circle. Feet move heel-toe-heel pattern. Major contributor to angular momentum.
Right foot lands first (still rotating), then left foot blocks. Hip-shoulder separation maxes here. Trunk rotation velocity = 40% of release velocity.
Hips lead; shoulders unwind; arm fires last. Discus released at 32-37 deg with release velocity 20-25 m/s.
Right leg switches forward to absorb momentum.
