Very simple, but effective and powerful! Nice stretch created.
Interesting...I recently got a PM about speed and its creation. It stated that the hands, arms and wrists create the speed. I agree totally w that. BUT in order to get the hands across the body without dumping, casting, pushing or dragging the bat you gotta use the core and it’s contraction so you don’t have to compensate to create speed and use one of the above flaws. All of which create ‘holes’ in your bat path and will hinder your ability to adjust when needed. Each flaw creates different holes.
the core isn’t all of it. But it starts the swings speed without a flaw to obstruct. It’s all one system at the end of the day. Everything needs to be right to be as efficient as possible.
