Unfortunately, very few men know where their diaphragm is, or what purpose it serves. They think they know the position of their heart and their liver (although experience on the drill ground shows that they are generally wrong), but as regards their diaphragm, their ignorance is even as the night. As they plaintively remark, ‘How should they know? They have never been taught.’ And that is really the mischief. As children they were laboriously instructed in the anatomy of the world: they knew what a promontory and a peninsula were, and could tell you the names of the principal rivers from China to Peru. But as for the anatomy of their body they were left in almost complete darkness. Many people cannot even spell the word diaphragm correctly; the ancient Greeks were so convinced of the influence of the diaphragm on mental and physical conditions that in their language the same word ‘phrenes’ stood for diaphragm and mind. It is a fact that if the diaphragm muscles are flabby and loose (as with undrilled men they almost invariably are), the whole mental system becomes infected with the resultant slackness. An alert mind is only secured by an alert body, and the call, ‘Attention!’ is, in fact, a stimulus to the abdomen muscles, which spring up vigorously and raise the weight of the body from the centre. A heightening of vitality and a sense of spiritual power follow as surely as it did on the ancient hymn—‘Sursum corda’—‘We lift up our hearts unto the Lord.’

Walking is of all forms of exercise the best for women; but it loses its value if a woman’s gait is radically wrong. Instead of walking from the hips, most women walk from the knees: the result is a strut, a shuffle, a stamp, a shamble, a waddle, or a hobble, never a true walk. To walk correctly, feet, legs and body must be under control. The feet must be allowed to keep their proper shape and position, and while the inside of the foot is used the toes should be planted in a straight line with the heel, never turned outwards. Uncertain balance produces bent knees, and one of the first results of a true walk is an increase of beauty in all the leg muscles, an increase of strength in the knees and in the deep-set muscles of the lower back. A woman’s knees, which nature meant to be strong and elastic, are now, with the abdomen, the weakest part of the female frame. There is nothing that women fear so much as a jump, and this timidity is purely the result of knee weakness, and the consequent inability to distribute body weight correctly. In the interests of health, beauty and comfort, correct walking is essential for women, and yet not one woman in a thousand would satisfy an expert.

To walk properly, then, the diaphragm must be on the alert, and a lifted diaphragm in a state of muscular tension cannot exist side by side with a large flabby abdomen. If a man’s body is to be beautiful, and if the man himself is to be in perfect physical condition, the abdomen must be reduced to the smallest possible dimensions and not overloaded with fat. The size of the abdomen is increased by the absorption of large masses of food, especially if they are of a gaseous and indigestible nature; it is decreased if the amount of food taken is reduced and if the food itself is rich in nutriment so that less bulk is required. Above all, if the muscles of the abdomen and back are strengthened by a carefully-designed system of exercises, they will take their share in bearing the weight of the upper part of the body and will prevent it from settling down, an inert mass, in the socket of the pelvis. As things are now, our hip muscles have usually too much work to do and are exaggeratedly developed, and an examination of any Greek athlete statue—the Diadumenos will serve as one example of many—will show that the Greek hip was much finer and slimmer than ours: it was more behind the body than under it and a far greater freedom of movement was thereby made possible.

An even more striking change will be seen in the muscles of the abdomen. With us a young, well-proportioned man has usually a depression just above the iliac ridge, and the iliac line descending from the hips to the top of the legs makes only a slight inward curve. In the Greek body we see a firm roll of flesh lying just above the iliac crest, the iliac line running beneath it for a short distance inwards in a horizontal direction, and then bending downwards at an obtuse or sometimes almost a right-angle.

Of this plain fact two explanations are possible. Either the ancient sculptors wilfully falsified their models’ contours in the interests of ideal beauty, or else this difference between the ancient and modern abdomen really did exist. The first explanation is highly improbable considering the Greeks’ artistic conscience, and furthermore in their statues of women no trace of this horizontal iliac line is ever apparent. The only reasonable inference is that these muscles, which with us are so undeveloped as to be invisible, were the result of the constant physical training to which the Greek man, but not the Greek woman, was habituated.

In an artistic sense there can be no doubt as to the excellent effect which the ancient line produces. It gives proportion and an air of solidity and greatly diminishes the superficial area of the abdomen. And that it represented a real condition rather than an artistic ideal is a very probable fact, for the statues of Greek athletes often represent positions which for us with our weak abdomens are almost impossible of attainment. One of the most perfect of all, Myron’s Diskobolos—the young athlete throwing the diskos—seemed to Herbert Spencer ‘an impossible contortion’; and after a close examination of its poise he declared that at the next moment—if the action were continued—it would fall upon its nose. It is quite possible that such a regrettable accident would have been the result if our revered philosopher had attempted to perform the movement, but the muscles of the Greek body, properly trained and hardened, found in it no insuperable difficulty.

The movement that Myron represents is the swing back of the diskos. The athlete has already taken his stance, and with left foot forward has extended the diskos horizontally to the front in his right hand. Then comes the decisive action: the whole weight of the body is transferred to the right foot, whose toes grip the ground at full tension; the left foot trails back, offering no resistance either to the pause or the coming momentum; the body swings round upon the fixed pivot of the right foot. The diskos held in the right hand comes downwards and backwards; head and body turn with it; the next moment the body will swing round again with a forward lift and the diskos will fly from the extended hand. Whether the force of the throw relies entirely upon the lift of the thighs and the swing of the body, or upon the arm alone, swinging rapidly in a free shoulder socket, will depend upon the weight of the diskos used. In either case it is the pause at the end of the backward swing that the sculptor has fixed in the bronze.

Only in imagination can we see the actions by which the body has got into this position and by which it will again recover its equilibrium. It illustrates one of Lessing’s sayings in the Laocoön: ‘Of ever changing nature the artist can use only a single moment and this from a single point of view. And as his work is meant to be looked at not for an instant but with long consideration, he must choose the most fruitful moment, and the most fruitful point of view, that, to wit, which leaves the power of imagination free.’

One of the greatest benefits that the ancient Greeks have bestowed upon the modern world, if only we like to make use of it, is the standard of bodily perfection they have bequeathed to us in the remains of their sculpture. Just as Greek literature is eternally precious, not only for itself but as a criterion of beauty, so Greek statuary supplies us with visible proof of the power and grace to which the human body with proper care and training can attain. Besides the Diskobolos we have an admirable example of slender vigour in the Hermes of Praxiteles, of athletic strength in the Hagias of Lysippus, of grave dignity in the Charioteer of Delphi, of poise and balance in the Archers of the Ægina pediment, and of what the Greeks considered perfect proportion in the various copies—all unfortunately rather late and lifeless—of the Doryphoros of Polycleitus, from which the sculptor himself worked out his ideal canon.

Of examples of female beauty we have an equal wealth, and almost every movement of the body may be illustrated from some extant statue. For walking, we have the Victory of Pæonius, stepping freely forward with her light linen robe blowing back against her girlish limbs, and the more mature figure of the Victory of Samothrace. To some modern critics both statues seem to be flying through the air, but the appearance of winged motion is in reality simply due to the fact that they are walking correctly, using about half the effort, and covering at each pace nearly double the ground that a modern woman would traverse.
