To enjoy the glow of good health, you must exercise.

A concave chest means that your diaphragm is sagging.

But I do say that, if you will regularly devote 15 minutes a day, preferably before breakfast, for 60 days to the simple set of exercises that I devised for conditioning men in the navy, I guarantee that you will enjoy increased physical buoyancy and mental vigor.

Though I was not a belligerent kid, I do not think I ever passed up a good opportunity to fight.

Handball, swimming, running, jumping, basketball, and boxing were as much a part of me as breathing.

In youth, we get plenty of exercise through games and running around, but as middle life approaches, we settle down, literally and figuratively.

As a West Side kid fooling around with boxing gloves, I had been, for some reason of temperament, more interested in dodging a blow than in striking one.
