I attribute my declining physical fitness through my 30s more to externalities than actual physical declines. I don't feel old by any means, but I have gotten noticably soft!

What I mean is that as I have progressed through life, I have gained more responsibilities (wife, mortgage, two young kids) that have left me with less time for physical activity.

There was a time when my regular Sunday morning activity consisted of a multi-hour bicycle ride, covering some 65-80 miles with friends. No way I've got the time for that now.

Couple the less activity with a diet that I adjusted less than I should have, and an undoubtedly slowing metabolism, and you get me at age 38, 30 pounds over weight, and on medication for high blood pressure.

It seems that this should be an easy "survival" project. All the BOBs, FAKs, gear and toys will not help me if I have an MI at age 45. I was inspired by Martin and his weight loss thread, but I don't have the discipline to do it on my own, so I'm trying Crossfit.
