Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Set up a stable platform at knee height. Load a barbell across your upper back, gripping firmly. Stand facing the platform, feet shoulder-width apart. Step onto the platform with your right foot, driving through your heel. Bring your left foot up. Step down with your left foot, then your right, returning to the start. Alternate leading feet.
Ensure platform stability. Engage your core for balance and lower back protection. Drive through the heel for glute and hamstring activation. Maintain an upright posture. Control the descent to protect your knees.
