Instead of camping out deep or shallow, stand where the ball is comfortable for you where they hit the deepest, and then, learn to walk-thru all balls during contact, like approach shots, and you will never have this issue. Each time you hit the ball moving forward, retreat to you original real estate position from where you started. Sampras used to do that all the time when he was just becoming great, around '90, when his groundies were still suspect because his serve was not yet too much for everyone. It kept his BH from being shredded.
