I’m going to buck the trend here and suggest pedaling less. I’ve lost a boat load of weight from low intensity work outs like walking and biking (at a moderate to low intensity). For me personally high zone training did nothing to help with weight loss and only benefited me for preparing for racing. I’m going to have to see the proof that the “fat burning zone” is a myth. Everybody is different, but for me it worked. So I’d say pedal slower to keep your heart rate down. If you are to the point that you can’t lower your heart rate, stop or walk and let it come down. I know it’s not cool and seems counter productive but it sure wasn’t for me. It’s hard to break the “go hard or go home” mentality of the old school way of thinking. I will agree however that daily exercise will help a lot. I shoot for 30-45 min. 6 times a week with at least 75% of that being at a low intensity.
