Danny,

Try this exercise. Stand up straight, feet shoulder width apart. Push your rear end behind you by bending from your Hip sockets, not curving your spine from the waist. This will tilt your spine forward. Flex you knees slightly. Put your rear end against a wall in this position.

Now, maintain the Waist Bend, by keeping your rear end behind you. Can you raise you head without taking your rear end off the wall and maintain your balance? Doubtful.

Now in this same starting position, move your hips forward in the direction of the ball. Your head came up automatically to keep you in balance. Your central nervous system lifts your head (changes your spine angle) to keep you in balance so you don't hurt yourself.

So to maintain a stationary head, maintain the proper Waist Bend (spine angle) by keeping you Rear end back behind you.
