Eustace Miles (1868–1948) is the author of Daily Training. Public information about his life is limited: his nationality, education, and career are not clearly recorded in the available sources, and only one of his works is held in this collection. Judging from its title and subject, Daily Training is a practical guide to everyday life, focusing on physical exercise and the formation of daily habits, and reflecting the author's idea of integrating training into ordinary routine. Works of this kind generally stress regularity, practicality, and gradual progress, and tend to use plain instructional language rather than theoretical exposition. Although little is known about Miles's other writings, the title Daily Training itself reveals his approach: helping readers keep up exercise through simple, scheduled routines. Further details of his life await more sources.
