I am concerned that I am 'arming' my strokes. The way I hit the ball is to do an extreme turn so that my chest is facing the back fence pretty much, and I'm looking all the way over my shoulder at the ball. Then, I forcibly push off the back foot and spin around through my trunk, trying not to use any muscles in my arm or shoulder - trying to keep my arm like a dead piece of flesh attached to my body. Whether forehand or backhand, I always hit every shot airborne - which I have to be because I'm violently spinning around at contact. Unless I want to twist my knees off I guess I have to be in the air. I'll finish my stroke with my chest roughly facing the side fence - having spun around a bit more than 180 degrees throughout the stroke. However - my problem is that although I'm trying to keep my arm as loose as a dead piece of meat attached to my body - I find I need to actively hold the racket. If I don't think about holding the racket (as people say you should do) - then it just flies out of my hand and nearly hits the guy on the other side of the net. If I have to think about holding my racket, then my arm isn't as dead and floppy and whip-like as I'd like it to be during the stroke. Can you guys think of any way to correct this?
