Funny you suggest that Marcie - Tony walks our neighbor's dog, when available - too slow for me - WHEN I walked I listened to music, headphones, and moved as wanted it to END!!!!! 2 miles 30 minutes my time THEN!!!!!! Walked early am and late pm total 4 miles - no doubt it works!!!! Also had personal trainer ugh! kids gave to me as b'day gift - this poor gal didn't know what hit her at 6:30 am when I arrived - 6 weeks of misery for both of us
