I did 10 minutes on the treadmill and I've done well with my eating. I was going to do another 10 minutes on the treadmill, but I'm not sure. My 8 and 10 year old nephews are here today and immediatly saw it and said "oh a treadmill!" And my mom told them it was strictly off limits. Kids .. with my almost 2 year old niece I'll have to put it under the bed.
