Review these articles before practicing your mechanics. 

Very good hitting article for you guys to understand the general physiological mechanics of the swing. You hear my say things like "Get into your hips" and "stay behind your hip" "hip shoulder separation/cork screw" all of that is in this article. Take some time to soak it in. Video tape yourself and then compare what you see to what you read. If you don't fully understand it talk to a teammate who does.
