Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Attach handles to the high pulleys. Stand centered, feet shoulder-width apart. With an underhand grip and arms extended, curl handles towards your head, flexing your elbows. Keep elbows stationary. Squeeze biceps at the top, then slowly lower to the starting position, controlling the weight.
Keep elbows fixed to engage biceps. Control weight throughout the movement. Exhale on the curl, inhale on the return. Maintain straight wrists. Choose a weight for 8-12 reps with good form.
