Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Kneel with hands wider than shoulder-width. Maintain a straight back and engage your core. Lower your chest towards the floor, bending elbows outwards. Stop just above the ground, then press back up.
Wider hand placement targets the chest. Engage your core for a straight back. Control the descent; avoid relying on gravity. Keep a slight bend in your elbows at the top. Inhale on the descent, exhale on the push up.
