The exercises are chiefly intended for use at home, and will be found to be more advantageous to the individual than any course of physical culture offered anywhere. No gymnastic equipment is necessary and no expenditure, save that of the time required, which will vary mostly from twelve to twenty-five minutes daily according to the time, need and inclination of the individual. ALBRECHT JENSEN, New York. * * * * * DR. WILLIAM SHARPE 20 West 50th Street, New York _March, 1920._ _Mr. Jensen:_ _Dear Sir:_ _It is a pleasure to recommend most highly your system of massage and exercises combined. I have observed the excellent results—from your method of massage alone—in so many of the patients at the Polyclinic Hospital—both in my own patients and in those of the other physicians that I do not hesitate to endorse your statements. The fact that no apparatus is necessary for the combined massage exercises, which are thus automatically graduated according to each person’s strength and condition, is a most desirable feature._ _They are especially adapted to be used by men, women and children as a permanent physical culture course._ _Very truly yours,_ _(Signed) William Sharpe._ * * * * * EDWARD LELAND KELLOGG, M.D. WILLIAM ALVIN KELLOGG, M.D. 48 West 51st Street New York _April, 1920._ _Mr. A. Jensen, New York City._ _Dear Sir:_ _I am glad to have had the privilege of looking over the manuscript of your system of combined massage and exercise._ _The results so far as I have observed them have been excellent. This combined treatment possesses manifest advantages over either massage or exercises given separately._ _The fact that no apparatus is needed and that the strength of the individual adapts the course or treatment to his particular need, renders it generally applicable._ _Very truly,_ _(Signed) E. L. Kellogg._ CONTENTS PAGE ATHLETIC INSTRUCTORS 13 RESULTANT BAD EFFECTS FROM THE USE OF HEAVY APPARATUS, WEIGHTS AND TOO STRENUOUS EXERCISES 15 SPECIAL BENEFIT TO WOMEN FROM THE USE OF THESE EXERCISES 17
