Hmm... I think the best thing you could do is to continue working on your swing mechanics, and develop the core muscle group. But then again, if you think about it, the triceps also contribue to your swing, as do many other muscles.
How long have you been lifting? What experience do you have with some of the more advanced, technical exercises? If you aren't lifting at the moment, "Get to it!" jk...
Look up some of KC's post, and some of the older threads. I think there may have been other threads that dealt with the question you're asking.
But things I have been taught: "It's all in the hips!"
And if you want, why not start a log? This way we can sort of help you out as you go along. KC's pretty knowledgeable in this area, and sadly, mike doesn't post here as often as he used to.
From mike on another forum:
I could pm you his number if you want to get in contact with him. His site doesn't seem to be working anymore?
Steve, do you know what happened to him?
Here's an article I found on bb.com
