Stamina

Most people have rather poor stamina. Most people also allow their stamina to deteriorate dramatically as they get older. They get used to lounging around and being physically inactive -- sedentary, even -- and it shows.

I looked at some photos of my old elementary school classmates, and it was pretty obvious that almost all of them had fallen badly out of shape. And to think that I was one of the least athletic people in our class way back when.

I watch these folks who attend our cardio boot camp classes at the gym. Most of them can't keep up for very long, even when they're barely doing the moves. The worst offender is this rotund fella who barely moves at all during the exercises, and who gives up easily. I don't think it's a question of being tired, since he scarcely works up a sweat and there are no signs of exhaustion on his face. Rather, he just doesn't put much effort into his moves, and so he's never going to see any real results.
