Okay, I don't think I know what I'm doing. I just picked up a racket five days ago for the first time in about 30 years. My natural grip is something like a baseball grip with my thumb on the top of the racket (like a thumb's up hand sign)... which obviously means my thumb is in the wrong position for strength... but it feels good. Anyway, an experienced friend of mine tried to show me a few grips but my brain didn't internalize it. I went to a few video sites and found a few videos on different grips. I tried them out today but after practice my hand hurt... like it was cramping or something. I don't know if my hand just hasn't developed the muscles yet or if I am doing something incorrectly. My natural grip has the handle running parallel to the knuckles which can't be right for tennis. The videos show to put the handle under the first fingers knuckle and the pad of my palm... like a 45 degree angle versus 90 which feels natural (like a baseball bat). When I do it this way my first finger naturally spreads out from the other three fingers so my thumb can fit between my first and second finger. Which I think is right. I tried the Continental, Eastern and several Westerns. I think. Again, I just looked at videos. The Eastern seemed the most powerful and a semi-Western naturally gave me a tilted down racket (for top spin) and a better follow through. Anyway, after 25 minutes my hand was cramping. Is this because I'm just a n00b or could I be doing something wrong? Also, if I am to start out with one predominant grip as a beginner (and I don't want to develop any more bad habits that are already come natural for me :shock: ) which one should I concentrate on for an all round game but mostly forehand, waist high shots?
