http://www.jeffsalzensteintennis.com/tennis-warm-up/ Some great old fashioned instruction that will help you develop power and consistency on your groundstrokes. I'm pretty sure Salzenstein knows the modern game better then most of the self-proclaimed experts on these forums. I already know what everybody's response is going to say. The pro's don't finish out front, the racket comes around their body. They must be pulling across. This advice isn't modern. This advice will give you girly strokes. Blah blah blah. This is a teaching tool to learn extension and a long follow through. If you learn this way, your follow through can still finish across your body as the racquet decelerates and comes around. There's a great article on tennisplayer.net where Robert Lansdorp talks about teaching Pete Sampras using this technique.
