Hmmm, I must be doing something wrong. You wouldn't believe I work for a computer company! I've tried posting replies twice now with a link to a video clip on You Tube of my swing... but the replies don't show up.
Thank you to those who have responded - yes my hips / ass move closer to the ball - my knees do not bend excessively - the head gets lower as I compress and pull in my upper body - lower body pretty much stays at same height e.g. knees/hips etc..
I'll hit return and if this post works I'll try again later with the video clip...
