My hubby and I are doing P90X and yes it was tough at first, but it has definitely been worth it! I feel so much better! I work a split week M, T, Th then T, Th, F night shift so I had to do it where my "off day" was on a day that I worked for sure. My "off day" is on Tuesday! But I also work at a hospital where fitness is promoted. We have a huge fitness center on campus along with a smaller gym inside the hospital which makes it easy to do something, even if its just walking on the treadmill for a few minutes. We have lots of fitness center promotions including a 12 week bootcamp that they do twice a year. Also, we have a wellness program that is tied into our benefits and insurance. It promotes checkups (both at the doctor and biometric screenings through our fitness center) that can reduce your deductible on your insurance as well as earn gift cards by doing different activities and earning wellness points. Our cafeteria also has a "fit n friendly" menu and special of the day.
I think it is harder at some of the other hospitals in our area because of atmosphere and hospital attitude towards fitness. It is definitely doable in any setting, you just have to be motivated and make it a priority. It surprised me how much better I felt when I went back to working out. I don't ned near as much coffee to make it through the night, and I don't crave the junk food as much. I still have days that all I want is a huge 500 calorie coffee on my way out of the hospital but thats a given and you gotta have a little leeway!:)
