Hey i recently purchased a bike in order to get in some mileage in order to lose some weight. I'm really overweight but 15-18 lbs wouldnt really hurt. Im 6'0 185 lbs and i just started riding yesterday. i rode 12 miles to the beach here in Fort Myers,FL, swam for 30 minutes and then rode back home. when i got home i went back on the scale to see how i did for the first day and to my surpise the scaled said 177. Is this a common thing to do to lose that much in one day. i used to be star athlete in high school 6 years ago so im very atletically inclined and would like to get back to that way. im tryin to get to around 160-165lbs range. any input would be appreciated and how often to people cycle for loss of weight, 3 times a week , 4?,5? everyday? .. thanks for reading.
