I could have written your post, hon. I'm also a college student, also have worked out when I'll go to the gym during the week while I'm there but I've been a
bum all summer. I'll admit it, I'm LAZY!
One thing I do during the semester is take a cardio kickboxing class at the University Gym two nights a week--so that's something that I just go to because it's actually FUN. The rest of the week, I plan to get up early in the morning (6:30AM) and get to the gym at 7 AM when it opens so I can get my workouts over with before my day begins. That way, I'll begin my day feeling accomplished, have my gym stuff over with for the day, and it'll make me tired enough to get to bed at a decent hour during the semester.
I think putting gym clothes out the night beforehand really helps. I'm not a morning person, but I know if I don't get my gym time done in the morning, I'll put it off and put it off until suddenly it's too late to go to the gym.
I want to get
some sort of exercise done while I'm home, too, though. I feel flabby.
