Dumbbells, Indian clubs, weights, patent exercisers and gymnasium stunts are all right for those who enjoy them. One thing to bear in mind is that short, choppy movements are not as good as the larger movements that bring the big muscles into play.
It is well to exercise until there is a comfortable feeling of fatigue. If this is done the heart works vigorously, sending the blood rapidly to all parts of the body, and the lungs also come into full play to supply the needed oxygen. This acts as a tonic to the entire system.
The body must be used to keep it from degenerating. A healthy body gives courage and an optimistic outlook upon life. A sluggish liver can hide the most beautiful sunrise, but a healthy body gives the eye power to see beauty on the most dreary day.
Those who are not accustomed to exercise will be very, sore at first, if they begin too vigorously. The soreness can be avoided by taking but two or three minutes at a time at first, and increasing until the desired amount is taken daily.
If the muscles get a little sore and stiff at first, do not quit, for by continuing the exercises, the soreness soon leaves. Many begin with great enthusiasm, which soon burns itself out. Excessive enthusiasm is like the burning love of those who "can't live" without the object of their affection. It burns so brightly that it soon consumes itself. Go to work at a rate that can be kept up. To exercise hard for a few weeks or a few months and then give it up will do no good in the end. However, a person may occasionally let a day or two pass by without taking exercise with benefit. Avoid getting into a monotonous grind.
I believe that the very best exercises are those which are taken in the spirit of play. No matter who it is, if he or she will make the effort, time enough can be found occasionally to spend at least one-half of a day in the open, and this is very important. We can not long flourish without getting into touch with mother nature, and we need a few hours each week without care and worry in her company. Many immediately say, "I can't." Get rid of that negative attitude and say, "I can and I will." See how quickly the obstacles melt away. There are many who are slaves to duty. They believe that they must grind away. They think they are indispensable. The world got along very well before they were born and it will roll on in the same old way after they are gathered to their fathers. The thing to do is to break the bonds of the wrong mental attitude and then both time and opportunity will be forthcoming.
I shall comment on only a few of the outdoor exercises that are excellent.
Swimming is one of the finest. There is a great deal of difference between swimming and taking a bath in a tub. Some people cannot remain in the water long, but if they have any resistance at all and are active, there will be no bad results. In swimming it is well to take various strokes, swimming on the back, on the side, and on the face. This brings nearly every muscle in the body into play and if the swimmer does not stay in too long it makes him feel fine. If a feeling of chilliness or weariness is experienced, it is time to quit the water, dry off well and take a vigorous dry rub. Swims should always be followed with considerable rubbing. The use of a little olive oil on the body, and especially on the feet, is very grateful. No special rule can be laid down for the duration of a swim, but very thin people should generally not remain in the water more than fifteen minutes, and stout, vigorous ones not over an hour. It is best not to go swimming until two hours have elapsed since the last meal.
Every boy and every girl should be taught to swim, for it may be the means of preserving their lives. It is not difficult. For the benefit of those who start the beginners with the rather tedious and tiresome breast stroke, will say that the easiest way to teach swimming is to get the learner to float on his back. I have taught boys to float in as little as three minutes, and after that everything else is easy. When the beginner can float, he can easily start to paddle a little and make some progress. Then he can turn on his side and learn the side stroke, which is one of the best. Then he can turn on the face and learn various strokes. This is not the approved way of learning to swim, but it is the easiest and quickest way.
To float simply means to get into balance in the water. It is necessary to arch the body, making the spine concave posteriorly, and bending the neck well backward at first. In the beginning it is a great aid to fill the lungs well and breathe rather shallow. This makes the body light in the water. Tell the beginner that it does not make any difference whether the feet sink or stay up. It is only necessary to keep the face above water while floating. If there is the slightest tendency to sink, bend the neck a little more, putting the head, farther back in the water, instead of raising it, as most of the learners want to do. Remember that the trunk and neck must be kept well arched, the head well back in the water. The moment the beginner doubles up at waist or hips or bends the neck forward, raising the head, he sinks.
For speed and fancy swimming professional instruction should be obtained. Swimming is one of the best all-round developers, as well as one of the most pleasant of exercises.
Golf is no longer a rich man's game. The large cities have public links. For an office man it is a splendid game. Women can play it with equal benefit. The full vigorous strokes, followed with a walk after the ball, then more strokes, exercise the entire body. It is good for young and old, and for people in all walks of life.
