Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Set incline bench to 30-45 degrees. Secure feet on pads. Lie back, hands behind head or crossed on chest. Engage core, lift upper body, twisting torso to one side. Elbow towards opposite knee. Slowly lower back down. Alternate sides.
Control movements to maximize muscle engagement and minimize injury. Keep core tight for stability. Avoid pulling on neck; use core to lift. Exhale on twist up, inhale on descent. Start with a lower incline and progress gradually. Maintain smooth, deliberate movements.
