Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Attach a resistance band to a stable anchor at shoulder height. Kneel facing the anchor, holding the band with both hands. Engage your core, keep your back straight, and twist your torso away from the anchor, pulling the band across your body. Pause at the twist, then slowly return to the start. Repeat on both sides.
Securely attach the resistance band. Engage your core for the twist, not your arms. Breathe out during the twist, inhale on the return. Stabilize your hips and start with lighter resistance if needed. Perform slowly for maximum muscle engagement.
