I'm 16 years old now, and I started ice hockey and tennis at age 10. At 13, I dropped tennis and began playing hockey full time. I still watch tennis and enjoy it till this day, and I would like to get back into playing it casually about two times a week. My cousin is a very good player, and I've forced him to play with me(he still thinks it's a waste of time to play with me

). Back when I played, my forehand was hands down my best shot by a mile. My backhand was decent, and my serve had good power but poor accuracy. My foot work and endurance is already good because of hockey, but making it better wouldn't hurt. Are their any threads/articles/books that I can read to help improve my game. If you guys have any other tips, I'd be glad to hear them. Thanks.
