Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Stand with feet shoulder-width apart, dumbbells at your sides. Arms straight, inhale, then exhale as you lift shoulders towards ears. Hold briefly, feeling trapezius tension. Slowly lower to start, inhaling.
Maintain a neutral spine. Avoid shoulder rolling; lift straight up. Use controlled movements. Start with lighter weights. Engage your core.
