hello

hi I'm a freshman in tenafly high school... I'm kinda so so tennis player,, but since I'm new to this forum, I have lots of questions to ask

1. How do I hit tennis ball hard and make it into the court? Some people say to use topspin or flat shot, but I think flat shot is much stronger. Help?

2. I need to know how to serve properly because whenever I try to serve, the ball just goes out, but sometimes, I get it in luckily.

I'd be really appreciated if you'd answer these questions..

its hard to answer those questions without physical assistance, you really just need to get under and brush up the ball and accelerate your body through to get penetration and power. For your serve you need to get high and over the ball, the higher you hit the ball, the more court there is to aim at. You could use kick serve which is safe and easy but maybe not for a beginner. Sorry i find it hard to help without physically assisting, just try new things out and practice and repeat.
