Approach
Run-up consistency, carry position, acceleration.
Approach. Crossovers. Block. Release.
Javelin combines sprint mechanics with a technical throwing action. AI video analysis of approach speed, crossover steps, plant, power position, block, and release angle, with coaching notes on the specific frame that cost you distance.
Run-up consistency, carry position, acceleration.
Rhythm, hip-to-shoulder separation building.
Impulse stride, javelin laid back.
Full separation, javelin horizontal, left side blocking.
Up-and-through release, release angle, follow-through.
Generic video tools look at "a person moving." We built a model specifically around javelin. the phases, the mechanics, and the coaching language real javelin coaches use.
Upload the rep. We extract the critical frames. You get a breakdown in plain English with priority tags. critical, worth working on, fine.
These are the technique patterns we see over and over again across javelin athletes. Each one has a specific look on video and a specific fix.
Your tip drifts downward in the power position, flattening flight and cutting 5-8 meters on a good throw.
Carry drills with a tip-up cue, and plant-and-freeze reps to groove the horizontal carry.
Your arm fires before the block foot lands, leaking energy before the chain can transfer cleanly.
Delayed-arm stand-throws, focus on feeling the block foot first, arm second.
Your plant leg bends on the block, losing the deceleration that transfers momentum into the throw.
Heavy-block drills against a board, and single-leg Nordic work to groove a stiff plant.
From freshman javelin to D1 rosters, athletes upload phone video and get the same frame-by-frame coaching read. The AI doesn't grade you. it explains what it sees, in the vocabulary a real javelin coach would use.
A directory of every javelin page on the site, from broad analysis tools to specific phase deep-dives. Each entry points to a focused write-up.
