The following chapters give a set of exercises carefully tested upon thousands of men, and these exercises will be fully explained so that any individual reader may practise them daily and secure their full benefit.

The object is to make an efficient working-machine of the man without useless effort, to increase that man's resistive force against disease, to add to his suppleness and endurance, to give him poise and balance, and to develop co-ordination or control over his muscles.

By doing this his power to work will be augmented, and at the same time any work that he does will be accomplished more readily and with less effort.

Finally his cheerfulness will be increased, and those who work with him or under him or about him will be spared the disagreeable experiences that accompany association with a man whose irritability and irascibility have become part of his daily habit.

The "Daily Dozen Set-up" consists of twelve exercises which, for ease in memorizing, are divided into four groups of three exercises each.
