Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
From a rings handstand, sink slowly with straight arms until the arms are horizontal and the body is inverted between the rings. Hold, then press back up to the handstand.
Do not descend below the point you can press back from. Requires a solid rings handstand and iron cross first. Keep the body vertical.
