With both, your feet hooked to the strap attachment, sit on the bench pad and secure the rope system. Start the movement by having both your hands on the back of your head. Take a deep breath and perform a sit-up in the decline position. Raise your upper body until it is 90 degrees with your legs. Ensure that your knees stay locked during the entire movement. Carefully lower your body weight down until it makes contact with the bench pad before going for another repetition. Make sure that your back stays neutral to prevent lower back rounding.
