Old thread: http://tt.tennis-warehouse.com/showthread.php?t=233986 Old serves: http://www.vimeo.com/2378765 Thanks to all who have helped me earlier! This is my new serve (only got around to record one, cuz I had like 1 minute left of the time I booked for the court). New Serve: http://www.vimeo.com/2698182 (And to LeeD, I looked a little lackadaisical in this vid because I can't consistently amp it up to the max speed and get the ball in, so this is a better representation of what I can hit like almost 90-95% of the time) Although it doesn't seem as fast as the ones in the old videos, I certainly feel as though I can amp it up if I wanted to, whereas in the old vids, even if I tried to amp it up, it probably wouldn't be much faster. Things I worked on: Rocking back less on the toss Lower elbow Trying to add better shoulder rotation Things I know I need to work on: Tucking in the tossing arm during the swing (I don't know why but I always forget to do this) Better shoulder rotation Better timing with the leg drive If anyone has anything else that they spotted, please let me know. My lifetime goal was to hit like 120 mph, but looking at my videos, my serves don't even look like they are 80-90. Thank you all in advance! PS:My new service motion looks cooler compared to my old serve too, thank you all!
