Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Anchor a resistance band high. Stand perpendicular to the anchor, feet shoulder-width apart. Grip the band, arms extended above one shoulder. Engage your core and rotate, pulling the band diagonally towards your opposite knee, keeping arms straight. Slowly return to start. Repeat on both sides.
Slightly bend knees for stability. Keep core engaged. Drive the movement with your core, not your arms. Exhale on pull, inhale on return. Control movements to maximize engagement and avoid injury. Adjust band resistance as needed.
