The first step of the forehand progressions is to establish your contact point and then shadow the follow through. Once you master shadowing, you can try and hit several balls from the service line.
Your contact point, if you remember the tennis forehand fundamentals section of the site, is about waist high, a little bit out in front of your body, and the racket face and your upper body are going to be facing the net. When I turn to the side at 0:22 you can see the racket is about a foot out in front of my body and waist high.
The key when you are learning the forehand in these progressions is understanding your hitting-arm position — the relationship between your tennis racket, your wrist, and your arm. This relationship that we have at contact, with your wrist laid back and your elbow bent, is going to remain the same before, at, and after contact. In fact, this relationship is going to remain the same basically throughout all of the forehand progressions presented here.
Let’s first start by standing at the service line and shadowing the motion. At 0:50, you can see that I have my body square to the net, and my tennis racket and arm are in the hitting-arm position at my contact point. My non-hitting hand is up at shoulder level and extended out in front of me. From my contact point, I simply extend out into my follow through slowly and catch the racket out in front of me.
Once you’ve mastered shadowing this motion it’s time to try to hit the tennis ball. Again, I’m standing at the service line with my body square to the net and my racket already at my contact point. All I do is push forward and follow through in this very, very simple motion.
From the back angle you can see that Andrej Loncar is feeding me the tennis ball. There is no body movement from my contact point. I just hit and follow through, pushing the tennis ball over the net.
