Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Position yourself on the ab coaster so your forearms are supported by the pads and your back is firmly against the backrest. Secure your knees on the designated pad and lift your feet off the floor. Initiate core activation and as you exhale, raise your legs toward your chest in a deliberate motion. Briefly hold at the peak of the movement, squeezing your abdominal muscles.
Focus on a slow, controlled movement to really target the abdominal muscles. Drive the leg lift with your core strength, resisting the urge to swing. Keep your head and neck relaxed throughout the exercise. Maintain constant contact between your back and the backrest. Begin with a lower number of repetitions and progressively increase as your strength improves.
