Ok-- but I see a couple potential issues with it from a teaching perspective: 1. The term is cryptic--so you have to explain it every time you use it. Something like "Serve up the mountain" is relatively intuitive and self-explanatory. "Human racquet" sounds like mumbo-jumbo. 2. We aren't used to thinking of our body parts as being passive burdens that we have to manipulate--when I move my hand, I perceive that as moving my hand, not as using my arm muscles to move a passive hand. So imagining that I am swinging a 10-pound racquet-arm combo doesn't really click for me. But hey, maybe I'll give it a try next time I hit. It can't possibly make my forehand any worse.
