If your talking about your "chin", this is not quite what you want. What really need to get out of the way are your shoulders. Do this by creating a better spine angle. Your shoulders will rotate about them on a 90 degree (perpenticular) plane, so where your spine is, this will dictate that angle.

Setup with your rear-end out more, your back straight and your tummy in. Flex the knees slightly and let your torso keep a firm base for the shoulders to rotate about the spine. You shouldn't have to worry about the chin anymore.
