Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Place your hands shoulder-width apart on an elevated surface (a bench or another support). Position your feet so that your palms are under your head when your arms are straight. Smoothly lower yourself by bending your elbows until your chest almost touches the surface. Pause for a split second, then press yourself up; keep your body straight the whole time. Repeat for the required number of reps.
The support should be stable and level so your hands are at the same height. Adjust the difficulty with the height of the support under your hands.
