I have been working recently on maintaining balance on my forhand stroke. I noticed and felt, that many times I was hitting off my backfoot and falling backwards. (If you watch the pros you sometimes see them do this as well... I assume out of the given situation) Do you have any specific drill or ideas on how to improve the balance on groundstrokes? (forehand specifically) In a related topic... I have had problems with the ball sometimes being too close to my body on the forehand side. Thus forcing a cramped swing. This will also affect balance as you need to adjust at the last second, and take an awkward swing knocking you off balance. Any ideas appreciated!
