This alternation is still more akin to the action of the body in standing and walking.
Allow the hip to extend outward on the same side which is being extended.
Co-ordination, that is a simultaneous and sympathetic union of many parts in one action or a harmonious variation of a primary response in many parts, is one of the primary characteristics of the organism. It can be secured by a certain feeling that the whole nature shares in the exercise, that the whole body responds to the whole being of man. It is a direct expression of joy and sympathy. In an involuntary performance there is always less co-ordination than in a sympathetic motion. These are feelings vitally necessary to co-ordination and we must not only have and feel them, we must express them in the body.
The alternation of exercises introduces rhythm, which has been found to be one of the most fundamental elements in training. Rhythm consists of proportion in time. This proportion is in alternation: alternation of activity and passivity, and in alternation of one part with another, as in walking.
Rhythm is the continuity of co-ordinations. Co-ordinations cannot be properly preserved without rhythm nor can there be rhythm without co-ordinations.
The exercises 2 to 6 should all be included in No. 1. They should also be individually practiced in order to accomplish the best results and to avoid the omission of any of these primary elements which should be present in and co-ordinate every true exercise.
After being practiced individually, exercise No. 1 should be practiced several times with a greater co-ordinating union of all the elements. The feeling of satisfaction and joy should be realized at once.
7. CO-ORDINATION OF PRIMARY CONDITIONS
Repeat Exercise No. 1; stretch first the right arm and also the leg, bend the left arm and left leg and so on in alternation. Preserve all the movements.
The difference between this exercise and No. 1 is the stretching of each side in alternation. The same elements should be included.
