I hate sit-ups. HATE. I hate my wiggly belly more. So, I gave these a whirl yesterday. I can barely move today. The chick doing the crunches makes it look easy. It is not. I fell on my face at least three times. Apparently Stacy Keibler is Pink’s trainer. I like Pink, but are women supposed to have a “Happy Trail?” Anyway, I am going to give this a week. Then, I will order another pair of Spanx.
