Shoulder flexion

Target Deltoids  ·  Equipment Body weight  ·  Level Beginner  ·  Reps 5

Shoulder flexion is a beginner-level physiotherapy movement targeting the deltoids, written in Posecode, a small open-source language that LLMs like ChatGPT, Claude, and Gemini can write to describe human movement as text. Every joint angle below is hard-clamped to a safe range of motion.

How to do it

1. Raise3s · ease-in-out Reach overhead, keep the ribs down
2. Lower3s · ease-in-out Control the descent back to the sides

The .posecode source

This is the exact text an LLM writes to produce the animation above: phases and joint angles, not 3D transforms.

posecode stretch "Standing shoulder flexion"
  rig humanoid
  pose start = standing

  step "Raise" 3s ease-in-out:
    shoulders: flex 170
    ground-lock: feet
    cue "Reach overhead, keep the ribs down"

  step "Lower" 3s ease-in-out:
    shoulders: flex 0
    ground-lock: feet
    cue "Control the descent back to the sides"

  repeat 5
