Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
From an inverted hang on the bars, lower the body slowly until it is horizontal and facing up, with straight arms and a straight line from shoulders to toes. Hold, then return to the inverted hang.
Pull the shoulders down and back to hold the line. Squeeze the glutes so the hips do not sag. Build up through tuck and straddle variations first.
MuscleTrain is actively being built. If something looks broken, or you have a suggestion, let us know — it really helps shape the app.
