This is a bit of a whine but the other side of this is they will work you 10-12 hours a day, not give you time to exercise then hold you to standards.
I am prior active duty enlisted Army (7 years, air defense artillery), and I will tell you what a real day is like. Get up at 4:30am, pt at 5:30am-6:30am, formation at 7:30am, at work sites at 8am, work til whenever (usually around 7 pm). If I got off before 7, I went to the gym or the track. I was a squad leader, so if I was lucky, I didn't have administrative paperwork to do at night at home. This was usually six days a week. There were many occasions when it was seven. Then there were the calls at 2-3am for drills or to check to see if the phone list was up to date (the first sergeant would call all of the platoon sergeants, who called all of the squad leaders, who called all of their soldiers) or to do a drug test. Of course, if we went in for a drug test or a drill, did we get to go home early? Absolutely not. We worked until 7 anyway. Someone can't pee on command? Take them for a run around the building a half a dozen times, singing cadences no less. We get a vaccination and your arm hurts? Then 50 pushups are in order. I haven't even mentioned going to the field for 2 weeks out of every month where I had to work 18-20 hours a day: manning the engagement control station, fixing the equipment, doing drills, moving from site to site, setting up camoflage, setting up barbed wire, organizing guard duty, being on guard duty (my longest stretch was 62 hours straight with no sleep; sleeping on guard duty was considered dereliction of duty), organizing chow, performing inspections, marching, marching, marching, generating after action reports, and going to meeting after meeting. Twelve hours a day...bah!
After I was discharged, I went to undergrad, then med school (which my military experience prepared me admirably for), and now I am in pathology residency with a hematopathology fellowship lined up. I am now considering returning to the military. Why? Because I have never encountered in the civilian sector the comraderie, the unit cohesiveness, or the opportunity for leadership and teaching that I had while I was in the military. Despite the BS and the bureaucracy, I had some of the best experiences of my life in the military. These qualities may not be as apparent in the medical field, as opposed to the combat field units, but I still believe that it is there.
It is unfortunate that so many of the physicians in the military are new (there is a shortage and lack of retention of experienced physicians, particularly specialists), and that they are only there because it was an easy way for them to get their school paid for with a stipend thrown in for living expenses. This is the absolutely wrong reason to go in the military. That is why I did not do the HPSP program and accepted the debt. I knew that the military will do what is good for the military, and I wanted to have choices, such as what residency I got and doing a fellowship. They will help me pay my student loans, provided that I go in for at least 2 years and apply every cent of ALL of the bonuses that I receive for those 2 years towards my student loans. I would get paid WAY less (the hematopathology fellow who graduated in June got a job for over 300k/yr). I could be deployed (been there, done that). I would have to relocate every 2-3 years (again, been there, done that; relocated 3 times in 7 years, not including deployment). I would have to run (which I despise) and work out at least 3 times a week. Are these things something that I can accept to have a chance to serve my country again? Absolutely.
The bottom line is that anyone in the military, including the physicians (those who did the HPSP program, and those who chose to make it a career) made the conscious decision to go in (or stay in). I applaud those who stay in to make it a career. However, everyone who goes in should accept that military regulations require that you be fit for duty, and this includes that you be physically fit and not overweight. Just because you are physicians shouldn't mean that you expect to be held to a different standard.
