Waltz box step

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

Waltz box step 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. 1 - right foot forward0.95s · flow Step forward onto the right foot and begin the waltz rise
2. 2 - left foot side0.95s · flow Step left to the side and continue rising through count two
3. 3 - close and lower1.05s · flow Close the right foot to the left and lower softly through count three
4. 4 - left foot back0.95s · flow Step back onto the left foot and begin the second rise
5. 5 - right foot side0.95s · flow Step right to the side, staying buoyant through count five
6. 6 - close and lower1.05s · settle Close the left foot and lower with control to complete the six-count box
