Marshall teaches the layers under the movement. Come back any time you want to re-learn a zone.

“Chambers are from left to right, and they are following where both of your hands are.”

A chamber ride keeps the exercise in one chamber while the hands travel the levels. A level ride does the reverse. Every pattern in the app is a path through the same five by five grid.

Marshall teaches this one on camera in the full series. This build uses an animated diagram and his own words from the Oct 7 session.
