I’m pleased to say that my shirt size is roughly the same. Oh sure, I put on a few pounds over the years (I’m 44 now), but I started doing P90X and Body Beast. Those two programs have really helped my aging geek body to get back in shape, and stay in shape. I highly recommend both programs. There’s also Tony Horton’s Ten Minute Trainer videos, and some other great workout videos from Beach Body at Amazon.
