Martial Arts and Kalari Biomechanics

Kalaripayattu, karate, kung fu, and taekwondo ask for different stances, but the camera can still judge the same mechanical facts: a stable base, a level pelvis, a knee that tracks over the foot, and a spine that does not collapse on the way down.

Nexday AI keeps martial practice inside its own journey. Buying the martial pass opens that studio. It does not open yoga, dance, or outdoor routes. Ultimate is the plan that opens every journey, including the live coach.

A shadow avatar holds the reference shape while the person repeats the strike or squat pattern. The comparison is side by side in the same frame, with a small picture-in-picture of the target so a partner watching a shared room can see the same cue.

Train on a clear floor, keep the whole body in frame, and stop when the fatigue cue appears. The coach can recommend a recovery break. It cannot diagnose an injury.
