Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Set the rings around waist height and grip them with palms facing each other. Position your body under the rings with arms extended and body in a straight line. Pull your chest toward the rings by bending your elbows. Lower yourself back with control to the starting position.
Adjust difficulty by changing your body angle and ring height. Keep your body straight and core engaged throughout. Focus on pulling with your back, not just your arms. Drive your elbows back to improve back muscle activation.
