does your college have swimming classes, boxing or martial arts(these require a lot of cardio)?
I'd also suggest training your abs and obliques since SL doesn't work your abdominals. (sit ups are useless as fuck, crunches are almost as useless)
Training for flexibility is another big one. Imagine doing a bicep curl with an invisible weight of 0kg. As you curl the weight all the way up, keep curling until your wrist touches your front delt. This is what Flexibility training feels like on your whole body. You are going to sweat like never before, your body will tremble, and those 90seconds in which you have to hold a stretch will feel like hours. When you are done with it, you'll also have DOMS in the stretched muscles.
