There are many exercises that can be performed with no apparatus whatever.  In all exercises we should practise deep regular breathing until it becomes a habit with us.  Most people acquire a faulty habit of breathing and only use a small part of their total lung capacity.  Learn to take deep breaths while in the fresh air.  After a while it will become a habit.

Just how much muscle a boy should have will depend upon his physical make-up.  The gymnasium director in one of our largest colleges, who has spent his whole life in exercise, is a small, slender man whose muscles are not at all prominent and yet they are like steel wires.  He has made a life-long study of himself and has developed every muscle in his body.  From his appearance he would not be considered a strong man and yet some of the younger athletes weighing fifty pounds more than he, have, in wrestling and feats of strength, found that the man with the largest muscles is not always the best man.

There is one question that every growing boy will have to look squarely in the face and to decide for himself.  It is the question of smoking.  There is absolutely no question but that smoking is injurious for any one, and in the case of boys who are not yet fully grown positively dangerous.  Ask any cigarette smoker you know and he will tell you not to smoke.  If you ask him why he does not take his own advice he will possibly explain how the habit has fastened its grip on him, just as the slimy tentacles of some devil fish will wind themselves about a victim struggling in the water, until he is no longer able to escape.  A boy may begin to smoke in a spirit of fun or possibly because he thinks it is manly, but more often it is because the “other fellers” are trying it too.

My teacher once gave our school an object lesson in habits which is worth repeating.  He called one of the boys to the platform and wound a tiny piece of thread around the boy’s wrists.  He then told him to break it, which the boy did very easily.  The teacher continued to wind more thread until he had so many strands that the boy could break them only with a great effort and finally he could not break them at all.  His hands were tied.  Just so it is with a habit.  The first, second, or tenth time may be easy to break, but we shall finally get so many tiny threads that our hands are tied.  We have acquired a habit.  Don’t be a fool.  Don’t smoke cigarettes.

Walking is one of the most healthful forms of exercise.  It may seem unnecessary to devote much space to a subject that every one thinks they know all about, but the fact is that, with trolley cars, automobiles, and horses, a great many persons have almost lost the ability to walk any distance.  An excellent rule to follow if you are going anywhere is this:  If you have the time, and the distance is not too great, walk.  In recent years it has been the practice of a number of prominent business and professional men who get but little outdoor exercise to walk to and from their offices every day, rain or shine.  In this way elderly men will average from seven to ten miles a day and thus keep in good condition with no other exercise.
