Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Attach handles to a cable machine at the lowest setting. Stand facing the machine, holding a handle in each hand. Step back to create tension, then bend forward until your torso is nearly parallel to the floor. Keep elbows close to your sides, bent at 90 degrees. Extend arms straight back, contracting your triceps. Pause, then slowly return to the start.
Maintain a slight bend in your knees. Engage your core. Keep upper arms stationary; move only your forearms. Exhale on extension, inhale on return. Use controlled movements. Start with lighter weights.
