Fat is one of the chief enemies of the heart because it has to be plentifully supplied with blood and thus needlessly increases the pumping load that the heart must sustain.

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

Exercise should be regarded as tribute to the heart.

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.

The man who has allowed his body to deteriorate cuts a pitiful figure – chest collapsed, stomach protruding.

I did six years of planning to win the championship from Jack Dempsey.

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

If all human lives depended upon their usefulness – as might be judged by certain standards – there would be a sudden and terrific mortality in the world.

A concave chest means that your diaphragm is sagging.

Never eat less than four hours before boxing. Then eat only lightly.

Fat is one of the chief enemies of the heart because it has to be plentifully supplied with blood and thus needlessly increases the pumping load that the heart must sustain.

Ever since boyhood I’ve made a religion of keeping in shape by regular, conscientious exercise.
