Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Stand with feet shoulder-width apart, holding a dumbbell in each hand at shoulder height, palms forward. Engage your core. Press one dumbbell overhead, fully extending your arm, while keeping the other at shoulder height. Lower the first dumbbell and simultaneously press the second overhead. Alternate arms.
Maintain a tight core. Control the movement, avoiding jerks or swings. Slightly bend your knees for balance. Keep elbows slightly in front to protect shoulders. Exhale on the press, inhale on the lower.
