Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Lie on your back, knees bent, feet flat. Hands lightly behind your head, elbows wide. Engage your core, lift head, shoulders, and upper back, twisting to bring your right elbow to your left knee. Extend your right leg. Return with control, then repeat on the opposite side.
Engage your core for the lift and twist, avoiding neck strain. Maintain controlled movements and keep your lower back pressed to the floor. Exhale during the twist, inhale on the return. Beginners should start with a smaller range of motion.
