Hi, I'm a teenis player (ITF Futures level) I used to do a lot of ace as 30 or 40 % in my first serve. Then, I had an injury (ankle) and I was awhile without training. I started playing again 3 month ago, and now  I don't have any confidence in my serve. For this reason I have to play with second serves almost all matches and practises. I would like to know what can I do. I would appreciate if someone could help me in this case. Thanks.  

Coaching tennis to middle school athletes for the first time. How do I begin?

There are 50 students, and I need to select 32 of them. How will you plan your try-out? Test for accuracy? Fitness?

I used to play on clay court for 20 years, now it's been two years that I've been exposed to hard court. About my game%3A I have a very good technique on all my strokes including volley, good kick serve, I am 192 cm. My issue%3A I was not taught to play aggressively, now in my matches I don't take the net; consequently, in spite of executing a high level tennis, I loose to some players that I never should. I've read some tennis mental toughness books, I teach them, but I don't know how can I change my own mental set. When I hit top spin (groundies), I enjoy and feel secure, even though it results in my loss and sorrow. I'm ready for change but how?

Psychology in tennis HELP!!! I have a daughter who is an excellent player who only started playing tennis seriously last yr at the age of 13. She is a much better player than all the people she has completed against in matches but always loses due to over hitting and getting upset if the wrong call is made (which happens frequently due to how fast she hits and serves) do we need some sort of psychological help for this. what is the best way to get this... books, councilling ??? any help would be most appreciated thanks

I coach 4-7 year olds, and when I'm teaching serves I usually start with the throwing technique without a racket, before introducing the ball toss. Someone has suggested I teach a catapult serve as a part of the learning process. I personally think this would teach bad habits as there is no toss up. Any opinions on this? Thx
