Never even heard of that, and am sure I couldn't do it.
I've you've ever played baseball, think of trying to line the ball to right center. To do that, the part of the bat that you hit the ball with can't get outside of where you'll eventually make contact, and then work it's way back. You have to hold back the contact part of the back/club, and feel like you're going inside out rather than outside in.
Obviously everyone's swing is different, and your problem could be different, but I'd start by going to the range and focus on taking the ball up the middle or to right center.
