It's not that bleak. Exercising for 30 minutes a day might not be feasible on some rotations, but you'll spend a large part of your day standing up/walking around. If you're really worried about "fitting in" your exercise routine, just use the stairs instead of the elevators whenever possible.
Or - you could volunteer to scrub in on
all the surgeries done on super-obese people. Retracting all that fatty tissue will really give your arm muscles a good workout!
[I'm only partly kidding.]
I can only speak for my own school (your experience does sound pretty brutal!), but I think the main advantage to being a resident over a student is that a resident actually "belongs" to a department. I agree with SLUser11 - at my school, it IS all about time management, but I feel like I could manage my time more efficiently if I weren't caught up in the stupid little administrative obstacles that come with being a student.
For instance, I never have time to eat breakfast...because I have to spend that time frantically flipping through Surgical Recall to figure out what will be going on that day. Why? Because I don't have access to the online OR schedule, and don't know what surgeries I'll be seeing the next day, so I can't prepare by pre-reading. [Yes, I've tried asking the OR nurses to see a copy of the next day's schedule, and gotten shooed away for my pains.

I don't have that many pee breaks...because I have to spend that time on the phone with Hospital IT, arguing over why hospital intranet access might be important to a med student.
And then, once they decided to "grant" me access, they changed my password without telling me. It took 4 phone calls to get it changed back.
On Gyn, I never ate breakfast, because it took me 20 minutes to get into the OR. Why? Because the hospital refused to activate my ID, so I couldn't get into the OR unless someone else happened to open the door. Since I couldn't depend on that happening in a timely way, I'd have to stake out the OR and wait for an opportunity to sneak in. My ID also wouldn't open the locker room, so I'd have to wait for a chance to get into the locker room and deposit my stuff. It was a huge, huge pain.
I do agree with SLUser11, though - on ENT, everything came together. I had online OR schedule access, my ID opened the OR door for me, and my password actually worked. It was amazing - I could actually pee, eat, and even check my email between cases.
