Here's a video of my serve about 2 weeks ago. This was after a 2 hours match, so I was a little exhausted. -The first file is at normal speed. http://www.zippyvideos.com/3787459312457866/thanatos/ -The second file is in slow-mo. http://www.zippyvideos.com/6128589942457896/thanatos_slow/ This is the usual topspin serve that I hit for all my matches. Both my 1st and 2nd serves are the same, except I add a little more spin on the 2nd to bring it down more. All the serves in the video landed in. I know I could use more knee bent and my motion doesn't look as fluid as I would like. Any suggestions would be appreciated.
