That sounds different than the Navy. We exercised once a year. If we could run 1.5 miles in 16 minutes then we passed. I ran 1.5 miles in 8 minutes. It took some people over 20 minutes to run 1.5 miles. Some people were so fat that they could not run. We did a lot of physical work but the fat people would hide to avoid work. Either that or they would get a medical excuse stating their back was bad and they could not lift more than 10 pounds. Have you ever noticed that most people with bad backs are overweight?
The Navys emphasis was more on training and knowing how to do things. The only people that I saw exercise regularly were the Navy divers, seals, and the Marines. I have always exersised 2 or 3 days a week because I feel better if I exercise. The Marines and Divers would invite me to exersise and target practice with them sometimes but I never had time to.
