Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Set incline bench to 45 degrees. Lie face down, feet planted. Grip EZ-bar underhand, shoulder-width apart. Arms hang straight. Curl the bar upwards, contracting biceps, keeping elbows stationary. Curl until forearms are vertical. Pause, squeeze biceps. Slowly lower to starting position. Repeat.
Keep elbows fixed, avoid forward movement. Use a controlled tempo. Eliminate swinging and momentum. Choose a challenging but manageable weight. Engage your core. Exhale on the curl, inhale on the lower.
