Chassé

Target Full body  ·  Equipment Body weight  ·  Level Intermediate  ·  Reps 4

Chassé is an intermediate-level dance movement targeting the full body, written in Posecode, a small open-source language that capable language models can use to describe human movement as text. Authored joint targets and reach-IK solves are constrained to Posecode's configured per-axis bounds. Those bounds constrain the visualization, but they do not certify that a complete movement is safe or clinically correct. This page documents a code example; it is not exercise instruction.

Movement phases

Phase cues are display-only coaching text. The executable joint and contact directives in the source below determine the animation.

1. Right foot reaches0.65s · flow Reach the right foot sideways and push away from the left leg
2. Left foot chases0.5s · flow Let the left foot chase under the body without breaking the sideways flow
3. Right foot reaches again0.65s · flow Reach right once more and finish the outward chassé
4. Left foot reaches back0.65s · flow Reverse cleanly and reach the left foot back across the floor
5. Right foot chases0.5s · flow Let the right foot chase under the body on the return
6. Left foot closes home0.7s · settle Close home over both feet and let the momentum resolve
