I had this problem in Washington state. I was taking all of my classes at the local community college (getting high school and college class). I didn't really have time to fit gym in to my full school and work schedule. Luckily, I have weak lungs and my doctor wrote me a note saying I had sports asthmas (true) and that was the end of that. I was thin and in-shape, so I wasn't that concerned about my weight.
