That is something I have tried, but no I don't have time for that. I catch a college bus with 1 and half hour ride (one way) at 8am and usually hack till 2am so I cannot just wake up at 6:30 to do some running even for half an hour. I come back at 6pm so that does not leave much room either. Actually that is the whole problem, I don't have time for doing something offline.
