Hello, I made two videos for shows the basic effects of serves. What can i improve?
When you say what can I improve, do you mean the video or the serve, I think a lot of the people above answering your post gave your improvements on the service but I got the impression you just wanted to show people the effects of the serves and I thought that was really well done, if that the case then it would nice to see your face and how you contacted the ball
If it's about how to improve the actual serve then I agree with a lot of what has already been said, the serves are spinny but maybe a bit too high, try and contact a little lower in the toss
