Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Stand with feet shoulder-width apart, holding dumbbells. Hinge at the hips, torso parallel to the floor, back straight, knees slightly bent. Let arms hang, elbows slightly bent. Engage your core and lift one dumbbell to shoulder height, alternating sides with the opposite dumbbell. Lower the first dumbbell as you lift the second.
Engage your core for stability. Avoid momentum; focus on controlled movements. Maintain a slight bend in elbows. Keep your back flat. Exhale on the lift, inhale on the lower. Start with lighter weights.
