If someone else has this issue I would like to know. I have been riding in earnest since May/June. I have logged around 1500 miles in that time frame. By my calculations, a male of my age (45) height (6'1") and weight (210) should have burned off around 70,000 extra calories which would result in a weight loss of around 20lbs. Nothing else in my lifestyle has changed all that much, and yet I remain at 210. I was hoping that this activity would get me down to under 200 but I am stuck. Don't get me wrong, I feel great and I'm sure that my heart thanks me, and I don't plan on not riding but I was just hoping for a better weight loss result. Any suggestions/comments?
