Jumping jacks is a beginner-level warm-up 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.
