Lying leg raise

Target Abdominals  ·  Equipment Body weight  ·  Level Beginner  ·  Reps 10

Lying leg raise is a beginner-level fitness movement targeting the abdominals, 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. Raise1.2s · settle Lift the straight legs toward vertical with the arms relaxed and the low back heavy
2. Lower1.4s · settle Lower the legs slowly while keeping the ribs quiet and the low back heavy

This is the exact text used by the linked playground animation: phases and joint angles, not 3D transforms.
