Now for my refutation. First, amongst my pupils have been many who, prior to coming to me, had been rejected as unsound by Life Insurance Companies; well, they have got their policies safely locked up now. Some had weak hearts, some poor lungs, others were generally unfit. They came to me, generally, for two or three months, applied again, and were accepted. Those who doubt my word can, as in the case of the Army lads, see the proofs for themselves. Is that good enough, or does “our friend, the enemy,” require any further demonstration that, far from injuring the vital organs, in many cases my system is enormously beneficial to those who are delicate. If so, here it is. They say _I_ am unsound; very well, here is an answer for them. Some months ago I was insured for a large sum in the Norwich Union Life Insurance Company; I was accepted in the _highest class_, and the doctor who saw me expressed great surprise at the soundness of my heart, the strength of my lungs, and in fact at the fine condition of all my organs. Surely these envious people show little ingenuity in inventing falsehoods which can be so easily disproved. CHAPTER IV. HOW TO EXERCISE. In commencing the system of exercises described and illustrated by the anatomical chart, there are certain questions which every student naturally asks himself. Probably the very first of these questions is, “What part of the day ought I to devote to these exercises?” The answer to this question must depend on the pupil himself--on his leisure and on his inclination. Some persons find the early morning the best and most convenient time; others prefer the afternoon; and a third class, again, find that they feel best, and have the most leisure, at night. I do not, therefore, lay down a hard and fast rule of time. The golden rule is to select such part of the day as suits you best, always avoiding exercise immediately after meals. If possible, let two hours elapse between a meal and exercise. Moreover, do not exercise just before going to bed if you find it has a tendency to keep you awake. Many of my pupils find that they sleep much better after exercise; but there are some upon whom it has a reverse effect. If possible, the pupil should always exercise stripped to the waist; if he wear a singlet it should be cut well away round the arms, so as to allow of free play for the muscles around the shoulder. It is also desirable to exercise before a looking-glass, for then the movements of the various muscles can be followed, and to see the muscles at work, and to mark their steady development, is itself a help and a pleasure. In performing the exercises the pupil should bend the knees slightly and keep the muscles of the thighs tense; the legs will thus share in the benefit of all the movements.
