I've been skimming through videos at http://www.youtube.com/user/FYB2007 I've been wondering about how the fundamentals of how to get the most out of the kinetic chain into reverse FH. BTW, I do not buy the notion that the reverse FH is for wannabees and not for club level players. Sometimes a reverse FH is appropriate as a defensive shot or when you want more spin/net clearance, because that's the best option given the ball you're trying to play. It seems to me that how someone uses the kinetic chain is more or less the same whether you hit reverse or windshield wiper FH. When I see Rafa hit a reverse FH in an open stance, he really loads up on his back leg, starts the kinetic chain by leading with his hips, and then the swing follows through with the famous helicopter finish. Interestingly enough, when he hits his windshield wiper FH, he loads up his weight the same. His follow through is, of course, across his body. When I see Fed hit a reverse FH, he loads up on his back leg too (but not nearly to the extent of Rafa). But the load seems to be for the sake of his leg pushing up on the shot rather than leading with the hips. Sometimes he'll pivot around his back foot when he needs a little bit extra juice. For his WW FH, he doesn't lead with his hips so much. He seems to use his kinetic chain to push up with his legs. Fed's FH looks more relaxed. That may be a function of his more laid-back practice habits as well as his Eastern FH grip (easier to hit through the ball). (BTW, both guys tend to hit a WW more often than the reverse). Does anyone else see the same things? If so, I'm wondering why Fed and Rafa use their kinetic chain (ever so slightly) different. BTW, I find both approaches useful in their own ways.
