1) $10,000 Mitt Romney money says none of you faggots know how to do a proper sit-up.
2) Even so, sit-ups are one of the worst exercises you can do for yourself physically. Sit-ups do not work out your core, but they test your core's endurance and strength. They also manage to fuck up your lower back in so many ways, but then again this is all taking into account that you do them in textbook fashion.
3) I do not use the term "faggot" as a derogatory term for men/women who suck dick/eat pussy, but for faggots and their faggotry such as "HEY HOW MANY SIT-UPS CAN YOU DO YEAH LOOK AT MY PRE-PUBESCENT HAPPY TRAIL I'M SO TOUGH!"
