Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Sit with knees bent, feet flat. Hold a barbell with a slight bend in your arms. Lean back, engage your core, and lift your feet. Rotate your torso right, bringing the barbell to your hip. Return to center, then rotate left. Continue alternating sides with control.
Engage your core to protect your lower back. Maintain slow, controlled movements. Avoid momentum; use your obliques. Keep shoulders relaxed.
