During World War I, the U.S. military commissioned Walter Camp to develop a set of exercises to keep fit, and he proposed the “daily dozen”—short, regular workouts that keep the body healthy and agile, but not exhausting.
Camp came up with this complex in part because he found the existing calisthenics exercises too complicated and boring. Another reason was the already familiar idea that modern technology is taking away from people the health and agility that were characteristic of our distant ancestors.
After the war, this set of exercises spread throughout the world. Pamphlets describing the “daily dozen” sold in millions of copies, as did audiotapes with instructions. The Camp complex became known all over the world.
What is the “daily dozen”
This is a simple workout that should be done easily and with pleasure. It develops flexibility, improves posture, muscle coordination and a sense of balance.
Camp argued that exercise has a positive effect on the functioning of internal organs, in particular the intestines, and also pumps cognitive functions, improving brain function.
The “Daily Dozen” is suitable for any adult, but is especially useful for middle-aged people who notice some tightness in the body and sit most of the day.
Since the exercises do not cause fatigue and do not require a lot of time, Camp recommended doing them every day at least once, and ideally three times: in the morning, afternoon and evening.
Camp also advised supplementing your workouts with ten hours of outdoor exercise per week (a little less than an hour and a half per day) to maintain health and longevity.
