Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Stand sideways to a cable machine, feet shoulder-width apart. Set the pulley low, attach a handle. Grasp the handle with the hand furthest from the machine, arm straight, close to your body. Engage your core, slight knee bend. Lift the handle out to the side until your arm is parallel to the floor. Pause, feel the shoulder contraction. Lower slowly. Repeat, alternating arms.
Control movements to maximize muscle engagement. Avoid momentum; focus on shoulder muscles. Maintain a slight elbow bend. Keep your torso upright and stable. Start with a lighter weight. Exhale on the lift, inhale on the lower.
