Long days at work coupled with lousy weather has turned me into a treadmill junkie. For the past two weeks I've run one hour a day on my treadmill. I put it at 12% grade--as high as it goes--and alternate 1/8th mile at a walk with 1/8th mile at a 9 minute per mile pace. The fast part always leaves me on the verge of puking and the walking part lets me recover. I don't have a scale but noticed today that my belt had to be cinched in another notch. That translates roughly to an eight pound weight loss for me. No diet changes in that period.
