Hi, my name is Hedi Alavi, and I'm going to talk about the average heart rate zone during cycling. So in order to find out your average heart rate zone during cycling, you have to know what your maximum heart rate is. In order to figure out what you maximum heart rate is, I suggest doing a field test. So start by warming up 10 to 15 minutes on a moderate level, and then start doing intervals, 30 seconds to 60 seconds long each. Now these intervals will get progressively harder and harder until the last interval you're exerting your maximum effort. Now at the end of that last interval, you want to go ahead and mark your heart rate, and that should be pretty close to your maximum heart rate. So from there, I like to keep it simple. I always do just three zones, so zone three is from 85 to 100 percent of your maximum heart rate. So that number that you just got from your heart rate monitor at the end of the interval. Zone two is from 70 to 85 percent of your maximum heart rate, so that is in your aerobic zone, but still working pretty hard. And zone one is from 50 to 70 percent of your maximum heart rate, so that's somewhere between, you know, your warm up and a little bit more into it, still an aerobic zone. So once you're done, once you start your cycling workout, from the very beginning to the end of it, and you're wearing a heart rate monitor, at the end of your ride your heart rate monitor is going to give you your average heart rate. Now you want to look at that average heart rate and make it correspond to the zone and to the heart rate that you've established for yourself.
