The hands or not the hands that is the question. In younger hitters they tend to try to guide the barrel to the ball with the hands. The heavy bag is good for breaking this habit by not worrying about the ball and just swinging into the bag. This allows you to work on the swing without trying to hit the ball. Then once they get the idea off the bag you work on hitting the ball without trying to guide the bat. You work on trusting your coordination, your tilt, swing plane to hit the ball. It's like in pitching where guiding the ball is harder then when you throw it harder, let it fly.
