Triple rhythm has a very sympathetic and stimulating effect. The run is more of a triple rhythm, while the walk is dual. All forms of rhythm, all of the metres should be introduced into the various exercises.
25. ROTATION OF LEFT SHOULDER
Turn over to the right side, and rotate the left shoulder in the same way.
Whenever an exercise is taken for one side it should also be given for the other unless there is special reason for remedying some condition of one-sidedness.
Exercises for the centre of the body should always be given the preference. There should be as far as possible a series of exercises.
Thus far, the exercises are all used lying down. They may be taken in bed but, of course, it would be better if the bed were firm and not too soft, not too yielding and as level as possible. The exercises would often be more helpful if taken on the hard floor.
It is better to sleep on a narrow cot as Cornaro did. This prevents our doubling up the body and contracting the vital organs. Everyone should lie down to sleep tall, or long, and as expanded as possible.
Another reason for sleeping on a cot is that there are no hindrances to lifting the arms behind the head in some of the first exercises. If we sleep on a bed, when we exercise, the body should be placed more or less across it so as to give more freedom to the arms, or the arms may be stretched out straight at the side although this is not so good.
26. ELEVATION OF CHEST AND BREATHING
Sit erect, as tall as possible. Expand the chest fully, carry the arms forward, then backward, gripping the hands almost under the shoulders, chest out as far as possible, taking a deep breath. Repeat this rhythmically many times, sustaining as far as possible the expansion of the chest.
