Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Begin with a barbell and a comfortable weight. Stand with your feet shoulder-width apart, gripping the bar with an overhand grip at shoulder width. Lift the bar vertically, keeping your elbows relatively straight, until your arms are parallel to the floor, then lower it back down under control.
Maintain an upright posture throughout the movement, avoiding any backward lean. Control the descent of the bar to prevent momentum. Allow your shoulders to fully flex at the top of the repetition. Focus on engaging your core muscles for stability. Lower the weight slowly to maximize muscle engagement.
