LEAGUE WATCH: Serving up disappointment

Mercifully, the fall season is over for our women's team. The mission was simple if we wanted to keep it going: Beat the other team in our division more than once. We came up a bit short, and my mid-match flake-outs are a big reason why in my book. You can't just play tennis once a week, and have that match be your competitive match. Well, at least I can't do that.
In the meantime, I've had the opportunity to work on my game with a group that picks up doubles matches four days a week. For the most part, I've been able to knock off a good chunk of the rust, but there's still a part of my game that's bothering me, and that's the serve. I think -- I think -- I have all the ingredients of a good serve, but very rarely do they all come together to create the booming serve I want. I'm not a big person, but if Justine Henin showed me anything, it's that if you have a good serve technique and you're four feet tall, you can have a strong serve. That's all I want, but I can't pinpoint what the problem is. My husband thinks I'm tucking my arm in and not getting off the ground enough, but I think the bigger problem is the toss and that it might be too low.
So I had a thought. I would record my serve practice and post it so you guys could help me! I had this thought about three weeks ago, and that's about the time it took to actually find a simple way to edit this short video. This is probably because I am not as technologically advanced as I had led myself to believe. As a result, this post is the fruit of about three weeks' labor, so enjoy it and feel free to offer any tips! If you do, you get a free subscription to Tennis With Attitude!
