To introduce Joe, he did not have a forehand until I started working with him. It was a disaster. I began working with him in the beginning of summer. We work once a week, and to be honest, his forehand has developed into a lethal stroke - probably developed a lot faster than people who work with a coach at least 3 times a week in the bay area. He now feels a lot more confident about it, and can really rip it when he chooses to. However, he is still new to this modern technique and working only once a week, it will take a bit to really get it down.
This is a picture comparison of a pro and him in the buttcap position. I really broke it down for him and addressed the problems in this comparison. And since then, we just kept working the mechanics of his stroke to get the forehand he has now.
I will try my best to get a video of how his forehand looks like now. I just taught him the secrets of using the hips and feet, and now his racket head speed is phenomonal.
