Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Lie back on an incline bench, head at the high end, legs extended off the low end. Grip the bench for stability. Keeping legs straight and together, lift them towards your chest by flexing at the hips. Raise legs perpendicular to your torso, or as far as comfortable. Slowly lower back to the starting position.
Maintain lower back contact with the bench. Control the movement throughout. Exhale on the lift, inhale on the lower. Slightly bend knees if needed. Adjust incline for difficulty.
