Hello all, as some of you may know, I started playing tennis back in May 2011 but really started getting serious and pushing the practice/drills the past couple of months. I finally decided on a racquet (Youtek Radical MP), so all of my focus from here on out will be towards practice and not equipment. Here's my serve so far (note, video has been cut to reduce lag between serves): http://youtu.be/InCVhXVafNs?hd=1 I apologize for the horrible viewing angle as you can't see my toss/racquet impact. I need to purchase a tripod mount for my iPhone 4S so I can properly adjust the viewing angle. This is my first time really watching myself serve and here are some conclusions that I came up with: - I really need to exaggerate my movements. When I'm serving I feel like I'm stretching long and bending my knees, but it clearly isn't the case. - I need more knee bend for more explosiveness - I need to bring my elbow higher and snap/throw through the ball more. - I need to extend my toss hand further up - I need to stretch my chest more and point it more upwards. - I need to lead with my racquet edge more to get more racquet speed. Obviously not all the balls are going in and my toss is all over the place. I promise I'm not muscling through the ball, otherwise I wouldn't last through 10 of those serves. I feel like this is a really big improvement over what I had a few months ago where I was trying to muscle through for speed. Practice sessions have been few and far between as of late due to weather and schedule but I hope to do more of these. Any critique or tips that you can offer me would be awesome Thanks everyone!
