Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
From a support on the bars, lower the hips back and swing the legs up until the body hangs inverted with the hips above the shoulders. Keep the arms straight, the core braced and the legs together. Lower under control.
Move slowly — no swinging. Keep the ribs down and the core tight. Come down the same way you went up.
MuscleTrain is actively being built. If something looks broken, or you have a suggestion, let us know — it really helps shape the app.
