Doing 100-200 sit-ups a day now. It's tough to keep my legs down, so I tend to do the shorter ones that don't go all the way up, but I can feel it burn which is all that matters. As I get better I'll do more and more until I can do 200 real ones every day.
What a dry entry. But I don't have much else to say. My classes are all pretty cool, and I'm looking forward to meeting more people this semester blah blah blah blah.
