I'm going to reveal some things about bat speed and hitting power that
you've likely never considered before. These are concepts and
techniques I personally mastered during my playing career and now teach
to my players and students. Because I have hit many a 90-plus mph
fastball, with a number of them landing well over 400 feet away, I know
what it takes to generate this kind of power.
Think about the game and its demands - just how strong do you really
have to be to play it well? In baseball, the ball is 5 ounces and the
bats weigh approximately 30 oz. Heck, a lot of young players swig cups
of Pepsi and Mountain Dew that weigh more than that! My point is this:

Baseball and Softball are games of explosive POWER,
not brute strength
Picking up a 30 oz bat is a measure of strength. Using it to blast a
baseball 400+ feet is a measure of POWER
