Grapevine

Target Full body  ·  Equipment Body weight  ·  Level Beginner  ·  Reps 3

Grapevine is a beginner-level dance 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.

1. Left step side0.65s · flow Step the left foot to the side and begin travelling
2. Right crosses behind0.65s · flow Cross the right foot behind without stopping the sideways momentum
3. Left step side again0.65s · flow Step left again and keep the shoulders quiet
4. Right touch0.55s · flow Touch the right foot in lightly before reversing
5. Right step side0.65s · flow Step the right foot to the side to travel back
6. Left crosses behind0.65s · flow Cross the left foot behind and continue through the beat
7. Right step side again0.65s · flow Step right and arrive back near the starting place
8. Close home0.65s · settle Close the left foot under the body and settle the phrase
