Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Set an incline bench (45 degrees) facing a low pulley cable machine. Attach a straight or EZ curl bar to the low pulley. Sit on the bench, back firmly planted, feet flat. Grasp the bar with an underhand grip, shoulder-width apart, arms extended. Curl the bar upwards, keeping elbows close and stationary. Squeeze biceps at the top, then slowly lower to the start. Maintain control; avoid momentum.
Keep elbows stationary for bicep focus. Use a full range of motion. Avoid body swing; maintain back contact. Control weight throughout the movement. Start with lighter weight to ensure proper form.
