Ha! I'm reading Marlins post and there's an add below for P-90x. I went through it last year and it really is pretty awesome. About a month in right now and it's kickin my tail, more so than last year which is surprising to me thus my concern about the age thing. As a sorta funny side note last year I got to the Yoga disc and thought, "oh good, a break"........I mean how hard could it be standing in one little area and moving slow right. It's an hour and a half routine and I couldn't even get 1/2 way the first time....covered in sweat, grunting and groaning.....whew!
