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. Watch this video on YouTube
