any exercise's

i had a lesson with my pro at the weekend and i was told i was pulling my body up to early and therefor getting a slight fade

does anyone know any exersices  i can do to help keep my body down.

I try to concentrate on my head staying still. try to imagine your head is stuck in a vice.

I try to imagine that my body rotates around a central axis which is my spine. Imagine a globe and they way that turns freely around the two points holding it on its stand. I use this thought when I feel myself swaying during my swing and it seems to cure most of my faults. I'm no teacher and it could be the wrong thing to do but it works for me. Anyone got any views on my 'Cure'?
