Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Set the cable machine to a low pulley with a straight bar. Sit facing the machine, feet flat. Grasp the bar with an underhand grip, shoulder-width apart, forearms resting on your thighs. Maintain a straight back and engaged core. Curl your wrists upwards, isolating forearm muscles. Hold briefly at the top. Lower slowly and controlled.
Isolate wrist movement; avoid elbow or shoulder movement. Start with a lighter weight and gradually increase. Use slow, controlled movements. Exhale on the curl, inhale on the lower. Maintain a firm, comfortable grip.
