Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Walk forward until you feel tension. Lean forward slightly, allowing arms to pull back. Keep elbows bent, chest lifted, and maintain a neutral spine. Step back to release.
Focus on drawing your ribs down towards your hips to stabilize your core and prevent overarching. Actively lift your chest towards the ceiling to open your shoulders and engage your upper back muscles. Keep your palms facing forward to encourage external rotation in your shoulders, promoting proper arm positioning. Consciously pull your shoulders away from your ears to prevent shrugging and maintain a relaxed neck and upper back.
