Almost guaranteed that if you swing a bat that is too heavy when you are learning to swing your mechanics are going to be flawed.
To use an extreme, imagine trying to swing a 48 oz. bat. You may be able to hit the ball in some way, but guaranteed it won't be pretty.
Swinging too light doesn't risk bad fundamentals as much as too heavy.
Baseball players have learned that a bat too heavy is a disadvantage.
No question ... having too heavy of a bat will impact performance ... and even cause you to use different muscles to accomplish the task at hand.
At my first two hitting sessions today I had girls going back and forth between their normal bat and a bat that was 2oz heavier than their normal bat. In the beginning most of them felt a significant difference. Towards the end, all but one girl showed improvement in terms of swinging with a tight HPP. None hit 'better' with the heavier bat than their normal bat ... but all improved in swinging the heavier bat towards the end of their session ... and all but one girl improved in terms of swinging with their body versus swinging with their arms.
48oz! I hear you. Just 2oz can make a noticeable difference.
