Sit on the lever machine with your chest firmly against the chest pad and feet secured under the foot supports. Grip the handles for stability. Keep your hips fixed and engage your core. Slowly curl your torso forward by contracting your abs, bringing your chest toward your knees in a controlled crunch motion. Pause briefly at the bottom and squeeze your abs. Then slowly return to the starting position without letting the weight drop. Keep tension on your core throughout and avoid using momentum.
