jump (don't be specific...when you land...your legs should be about shoulder length apart...this should be how wide your stance is)

door knocking knuckles, make sure your knuckles line up

hand & bat placement: if your bat is way behind your head...it's called wrapping around your head. make sure you don't do this. Bat speed is the most important thing in hitting. And wrapping the bat around takes too much time

Your hands are a big factor. if your hands are up, you'll probably hit ground balls, if your hands are down, you'll hit pop ups.

WAIT ON THE BALL. Don't be overanxious. if you're out in front...sure you'll make contact, but it will stay in the infield. This means you're using 60% of your batspeed. you're cheating yourself out of power. if you get it in the middle of your body...you'll be using 100% of your bat speed, this creates home runs.

Use both eyes. Most hitters make the mistake of using just one eye. Turn your head to where you have a clear picture of the pitcher.

While in the cages or anywhere swinging, focus on getting power from your legs. If you're knees are not burning, you're doing it wrong.

watch the pitchers release....this is a bonus. The best batters know what the pitcher is throwing and where the pitch is going because they notice where the pitcher's hands are and how he is throwing it. The only pitch this does not work for is the knuckle ball.
