Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Start in a push-up position, hands slightly wider than shoulder-width. Cross your right hand over your left, forming an 'X' shape. Maintain a straight body line and lower your chest towards the ground, keeping elbows close. Pause briefly, then extend your arms back to the starting position. Alternate arm crossing for balance.
Engage your core and keep elbows close to your body. Control movements, avoid rushing. Modify to knee push-ups if needed. Inhale on the descent, exhale on the push-up. Alternate arm positions regularly.
