I'm 16 years old, 5 foot 11 inches, and weigh 276 pounds. You couldn't tell from looking at me but that's beside the point. I want to lose weight and for the past 3 or 4 days have been using an exercise bike. I've been doing it for an hour, at the lowest resistance for 20 minutes, one higher the next 20 minutes, and another higher the last 20. And I let myself cool down at the end. I don't want interval training but I do need to know, is this going to help me lose weight. So far I've lost a pound or 2, and yes I'm also watching what I eat. When I do the bike for the hour I lose about 480 calories, which to me is nothing, but I don't really eat much any more. I don't starve myself though. And I drink enough water. So I just wanted to know, am I doing it right? My heart rate gets up to 130-132 at the last 20 minutes. Please help.
