So winter is coming and I overindulged again on Thanksgiving, and I want to know- Do you TPI?

I've watched the show on Golf Channel, and I've done some of the workouts, but I think I'm gonna do some TPI this season.  I used to work out for hockey when I played throughout college.  After that I worked out to ski, but now the only sport I play seriously is golf.  It makes sense to me to work golf specific muscles.

Has anyone here done TPI?  How was it?  What did they do?  Did you improve?
