Bad Habits

Today, in substitution for biting my nails, I did 250 sit-ups. I just turned on my radio and got to working out. It took me about 20 minutes, and I was doing them pretty fast but I had to take breaks after about 50. I just did 5 sets of 50. It was pretty hard on my stomach, but no pain no gain I guess huh? Now, I feel a bit refreshed and tired but it is definately for the better! I resisted biting my nails all day today, but that my be because there aren't any nails to be bitten. They are already bitten. Oh well, still feels good to be working out feeling the burn again.
