Hello everyone,
I have recently began riding a bike again after a 20 year hiatus. I'm 6'2" and 220 and hoping to lose some weight. My rides started about 2 months ago. It started with about 6 miles and now I'm up to 12 miles. I try to ride 3-4 times a week. My house has hills coming and going. My weight has not changed. I'm eating about 2000 calories a day. My rides average 40-45 minutes in HR zone 4. My heart rate goes up pretty fast and stays there most of the ride. I know to burn fat I should stay in zones 1 or 2 but I can't get my heart rate down.

Am I on the right track? Does it just take more time? Any suggestions or questions? Thanks for your help.
