Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Attach a bar to a low pulley. Stand facing the machine, feet shoulder-width apart. Grip the bar with an overhand grip, hands shoulder-width apart. Keep elbows close to your torso and back straight. Exhale and curl the bar upwards, flexing your elbows and keeping wrists straight. Curl until forearms are vertical. Pause, squeezing biceps and forearms. Inhale and slowly lower the bar with control.
Keep elbows stationary to isolate muscles. Avoid body swing; maintain strict form. Start with a lighter weight to ensure proper form. Engage your core. Use a controlled tempo. Keep wrists neutral.
