You can do so many other things you could do besides work out. Climb a climbing wall. Hike a mountain. Ride a bike somewhere. Swim. Wrestle. Box. Windsurf, my latest hobby.  Interestingly, all these things, compared with a good diet, tend to make a very decent body, not as big as that of body builders, but OK. So comics guy can only stay fat and ugly by actually missing a lot of things in life.
