I was teasing my wife about her "bilbil" as she calls it so she got so self conscious about it that she started jogging again. She also started doing sit ups at home. She started with 5 and I was laughing because she had a hard time with it. The next day however, I was impressed because she did 10 and I only asked 7. Yesterday she was doing her sit ups again but our son EJ interfered, he rode on Mommy's tummy lol..
