Just what I needed to add to my winter challenges. Marci had this on her blog, the 200 situp challenge. I had actually started my own situp challenge back when I started the 100 pushup challenge, and had gotten to 100. Since then, I've been doing at least 50 at a time most days, and the weight training class I've been taking for the last 6 weeks also has an ab portion at the end of the class, where we devote 10 minutes straight to ab work, so I think I'm in good shape to start this challenge. There's nothing that helps you look better than trim abs and well shaped arms. So let the challenge begin!
