Beyond the obvious, there are a lot of little things that you can apply to your own forehand. For example:
* Open stance and upper body rotation - saves steps and allows to build up momentum at the same time
* Other hand provides balancePoint of contact is in front of the body, wrist is straight behind the racquet on impact, and the racquet is rectangular to the ground - provides stability and control
* Arm swings all the way through and takes the upper body with it (note where the elbow and especially the shoulder end up) - leveraging all the built-up momentum.
Pretty nice! Anything else you notice?
