I've returned playing tennis less than a month ago. I was never a good player, hence my immediate need for improving. I'm 17 now and I'm going to college next year, so I'm really looking forward to getting in a good shape in order to be approved at the college's tennis team.
I'm getting started with improving the serve, still learning how to serve with a continental grip. This video may be in low quality, but these were the best serves that I could deliver in that day. Hope it's clear enough so you guys could comment it.
Thank you very much!
