The hammer throw is the most rotational event in track and field, 3 or 4 turns through the ring before release. It is closer to discus than shot put, but with more axes of motion to coordinate. If you also rotate for discus, the footwork patterns transfer. Pair with the discus technique breakdown for the rotational fundamentals.
Two preparatory winds set the rhythm. The hammer should accelerate over the right shoulder (right-handed thrower) and reach 180-degree extension before the first turn. Most beginner errors are short, choppy winds that lose tempo.
Each turn has a single-support phase (one foot on the ground, hammer at the high point behind the thrower) and a double-support phase (both feet planted, hammer at the low point in front). The 3 or 4 turns build velocity by lengthening the radius.
At release, the left foot blocks (right-handed thrower), the body opens up, and the arms whip through to a high finish over the left shoulder. Release angle is around 42-44 degrees. The thrower must stay in the ring.
Hammer throw is too fast to coach by eye. AI form check extracts the key frames, low point, high point, double-support position, release angle, so you can see what you are actually doing instead of what you think you are doing.
