Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Grip both bars with a neutral grip and press up to a straight-arm support. Lock the elbows and push the shoulders down away from the ears. Hold the body upright with legs together and toes pointed, core tight. Breathe steadily.
Lock the elbows fully. Depress the shoulders — do not shrug. Keep the legs together and still. Build hold time gradually.
MuscleTrain is actively being built. If something looks broken, or you have a suggestion, let us know — it really helps shape the app.
