Generic drill lists don't tell you which drill to do this week. Our AI identifies the specific error in your javelin and matches the drill that addresses it.
Block-start drills, plant drills, release drills. Javelin broken down by phase, train the phase that's holding back the rest of the rep.
After a drill block, upload another rep. The AI tells you whether the error closed up, or whether more reps of the drill are needed.
Run the drills, re-test the form on video, repeat. Javelin drills become measurable, you can see in the next analysis whether the error closed up, instead of guessing.
Follow up in chat and ask questions. The AI remembers your analysis and speaks the language of javelin coaching.
