I recommend raising the bar that is placed behind your shoulders to that it is in line with the top of your shoulders and the bottom of your neck. Doing so will help you to keep your shoulders open as you lift the legs, isolating your core muscles rather than allowing you to use your lats to do this exercise. Additionally, try to keep your ears covered by your arms throughout the movement.
