Neck side stretch
Neck side stretch is a beginner-level desk & posture movement targeting the neck, 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.
