1917 publication Physical Training for Business Men
by American author Harrie Irving Hancock. The book's premise is that a certain quality of physical presence, "impressive carriage and appearance", are essential to "those who would succeed in the business world". This is not, however, all about pure athleticism. Despite his strength and endurance the athlete "may show many signs of bodily slovenliness" which would negatively effect his business dealings. More important than brawn is to foster "the appearance of physical ease, alertness, grace, and discipline."
