Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Begin seated on a bench with your feet firmly planted and dumbbells in hand. Lean forward from your hips, aiming to keep your torso level with the floor and your spine straight. Allow your arms to dangle, maintaining a slight bend in your elbows. As you exhale, draw the weights upward, focusing on contracting your shoulder muscles.
Keep your abdominal muscles braced to provide a solid foundation. Resist the urge to swing your body; focus on deliberate, controlled movements. Preserve the natural curve of your spine and prevent your shoulders from hunching. Select a dumbbell weight that lets you perform the exercise with good form throughout the entire range of motion. At the peak of the movement, actively pinch your shoulder blades together.
