Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Attach a handle to a cable pulley set at shoulder height. Stand sideways to the machine, feet shoulder-width apart, holding the handle with your outside hand, arm slightly bent. Step away to create tension. Engage your core, stabilize your torso, and pull the handle across your body in a reverse fly motion, squeezing your rear deltoid. Pause at the top, then slowly return to the starting position. Repeat as needed, alternating sides.
Maintain a slight bend in your elbow. Focus on rear deltoid activation, avoid momentum. Perform slow, controlled movements. Keep shoulders level and avoid torso rotation. Start with a lighter weight to ensure proper form.
