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.

Exercise should be regarded as tribute to the heart.

A boxer must exercise and develop every part of his body.

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

A boxer's diet should be low in fat and high in proteins and sugar. Therefore you should eat plenty of lean meat, milk, leafy vegetables, and fresh fruit and ice cream for sugar.

Why does my blood thus muster to my heart,Making both it unable for itself,And dispossessing all my other partsOf necessary fitness?
