Hearing different things. I read the Jack Dempsey book and he says to bend almost exclusively at the hips. He makes a point to say that you should bend your knees as little as possible. But now I'm paging through the fighting fit book and it says the opposite.
Unfortunately I don't have a boxing trainer. My background is in Muay Thai, and this is a technique that was never taught to me, but I'm very eager to understand. Thanks for any insight.
