LOL, Robert! I feel your pain...it's really hard to stick with an exercise program when you're doing it by yourself. Is there anyone who will work out with you? Your wife, maybe?
I have been lifting free weights off and on since I was a freshman in high school. I got started because at 5'6" and 135 lbs, I was tired of taking sh*t from bullies. Then I got addicted to it. Over the years I've taken layoffs of as long as 2 years, mainly because I couldn't find a partner, and exercise is incredibly boring when you're doing it alone.
Right now I've been lifting with the same guy for about two years. We're on a maintenance routine...we're not trying to get bigger, we're just trying to keep our chests and shoulders proportional to our beer bellies. I'm now 195 lbs, of which I'd guess about 30 lbs is lard (pizza and beer).
That scale swinging up near 200 is like a flashing sign: "Caution: Middle Age Ahead!"
