How important is it to stay grounded on your forehands? I hit with an open stance, semi-western grip, and really like to put alot of pace and spin on the ball. The problem is, at least according to my coach, that I should be staying on the ground and staying low. I seem to either push off on my back (right) foot or to come off the ground a little off my toes. My coach is a very good coach, and was very succesful as a player in his younger days, and still is a great player, but i'm not sure if he's completely right here, since he's more schooled in the flat-hitting, older school style, while my game is obviously new school. So my questions are how important is it to stay grounded, and if it truly is very important, what are some tips to stay grounded while still being able to basically keep my same stroke?
