Front kick

Target Hip flexors  ·  Equipment Body weight  ·  Level Intermediate  ·  Reps 5

Front kick is an intermediate-level martial arts movement targeting the hip flexors, 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.
