Several pros -- Federer, Nadal, Verdasco, Tsonga, for example -- do something else to hit a WW forehand. Their WW motion is created by turning their hand / forearm over, which is what you allude to in #3. This starts right before contact and, of course, is most noticeable during the follow through.

Verdasco is a great guy to look at because he makes this motion very obvious. When you watch the following video, look at how much he drops the racket down, below his hand during his foreward swing. However, at contact the racket is often in-line with his hand because he has turned his hand and forearm over to bring the racket up.

IMO, this second method is the superior way to hit a WW forehand IF YOU'RE GOOD ENOUGH TO DO IT. It's definitely way more difficult that the first method. The reason we taught the first method is because it only requires a couple adjustments to hit, assuming you have a fundamentally sound forehand. The second method, however, is superior because it allows you to disconnect the direction your arm is swinging from the WW motion. In other words, your arm isn't responsible for creating the WW motion, your hand and forearm is. Take Federer -- he can hit extremely hard -- swing straight through the ball -- but still be very consistent because he uses his hand / arm to generate topspin. Nadal, on the other hand, has a much more vertical swing path AND turns his hand / forearm over to produce the WW motion. That's why he hits w/more topspin than anyone else on tour.

If I were going to recommend a progression for learning the WW, I would definitely suggestion the easier method #1 to start. Keep in mind that you can have a world-class, top-10 forehand with this technique.

1) at seconds 8-10, note the head height take back. The drop at seconds 10-11 initiates the power in the swing

2) freeze around seconds 9-10 and you see a closed stance, with the shoulder/torso/hips in line with the intended direction of the ball. Even if you go to a more open stance with the hips, you still want to line up the shoulders

2a) freeze after the swing at 15/16 seconds and you see her hips are parellel to the baseline, meaning that she made a 90 degree hip rotation. also note that the butt of the racquet/left elbow is pointed to the intended target after contact, indicating a 180 degree shoulder rotation from the stroke.

3) Note at second 10, left foot is in the air and at second 12 the right foot is in the air, indicating a full weight shift

4) ***Note that at around second 11, the hips rotate/open toward the net while the racquet stays back - this is similar to professional golf and baseball swings. This motion is key to the kinetic chain and stretches the muscles in the arm to make the ensuing swing more powerful***

5) freeze at 13 and note the extension of the left arm after contact, meaning she has pushed through the shot and brushed up the back - this is where a lot of power is lost in rec players who stop swing forward after contact and cut right to the finish over the shoulder. I like the think of pushing and not swinging with the left arm更多精彩文章及讨论，请光临枫下论坛 rolia.net
