The way I see it, as far as PT goes, the services are slowly migrating to the Marine Corps way–not only do you have the PRT’s and body fat thing, but you have to look good in uniform.
The Navy has historically been not too concerned with PT. The last 10 or so years has seen a slow change in the way we do business, though–there is more integration with the other services, and Navy folks are finding themselves deployed more and more as boots on the ground vice on the ship. So PT has become more of an issue lately, and the service has pushed to have commands carve out dedicated time for their sailors, or to at least be accomodating to PT-ing in general for a few hours a week. Not only does this protect the sailor by making him more healthy, but it will hopefully drive down healthcare costs, provide a better/more capable body to fill a boots-on-the-ground job, but also be less embarrassing. It doesn’t look good to send an augmentee to an Army unit who is almost bursting out of his uniform.
The Air Force, too, has seen its share of shaping. They were used to having a once-per-year physical test consisting of, I believe, a stationary bike ride. That’s changed over the last decade to becoming more like the Navy test (twice per year with run, pushups and situps), but with a stricter grading policy–I believe weight and/or waist measurements are factored in the score.
As far as my time goes, I currently have more of a desk job, 0730 to 1630. Being in the DC area, coming in late is perfectly understandable. Some days it takes me 30 minutes to get to work; other days it takes 50. I try to PT for an hour or two every day, but usually wind up only getting 3 or 4 days per week. If duty calls and I need to stay late, then I stay until whenever I’m done. When I travel, my days can run anywhere from 12 to 18 or 20 hours. “Weekends” are not applicable–every day is a workday. At home, weekends are my own unless something big is going on.
I’m slated to go to the sandbox in the summer where every day will be groundhog day for about a year and I’ll probably be standing 12 on/12 off shifts of staff work. Back in my squadron days, days consisted of training (both flying (aircraft systems, emergency procedures, etc) and preparing for deployments–studying the threat (aircraft, missiles, radars, visual recce (what aircraft and ships look like), orders of battle (what bases have what ships/aircraft), etc), current events and historical backgrounds of countries (i.e., why whatever country isn’t on our “friend” list))… this takes an amazing amount of time. When deployed, I would fly 11-12 hour sorties every now and then and in the down time I could either study, sleep, PT, or do whatever else I wanted.
This was my job as a flyer. Other guys, like the aircraft mechs, were busy depending on the health of the aircraft. Healthy aircraft=little work, and they were free to do what they wanted when not doing routine maintenance and other administrative things. If the planes were cranky, then they were busy as hell, working crazy long hours, trying to provide us something that would fly for the next mission (during which, of course, something else would break).
