I recently bought the Polar FT7 heart rate monitor. I'm confused by how to use the EnergyPointer feature on it. In today's workout, it said that I burned 409 calories, but I was only in the "Fat Burning" zone for about 5 minutes. The other 45 minutes I was in the "Fitness" zone. What does this mean in regards to weight loss?

I assumed this roughly equated to aerobic (fat burning) and anaerobic (fitness) training...but I think that is wrong. There is a youtube video that tries to explain it but it is like listening to a politician...he says a bunch but doesn't really say anything (http://www.youtube.com/watch?v=BpikZ8-uk2g).

But I found this at polar (http://www.polar.fi/en/support/product_support?product=22998&category=FAQs&documenttitle=%0AEnergyPointer&document=/gip/PKBStoGIP.nsf/web_cat/C225742500419A8AC22574500024A037?openDocument)

..inn the end, I think the fat burning segment is suggesting you are burning calories but not exercising enough to breakdown (and thus build up) muscle and it is not enough to help improve how much your heart can handle (ie cardiovascular fitness). The threshold is 69% max heart rate I think. So how might I use it, if I had a tough workout the day before or I am just not feeling "it" but I still want to work it...the "fat burning" phase may be a good range to hang out in because I will be burning calories but not additional stressing out my body.

Clear as mud?

I just got an FT7 :)
According to their website, when you are in the fat burning zone, your body is mainly using fat as the source of energy. When you go into the fitness zone, you start using carbohydrates more. So if I am understanding correctly, you can actually be better off keeping your heart rate lower, in the upper end of that fat burning range, if you want to burn fat/lose weight. I think this page explains it pretty well... http://www.polar.fi/en/training_with_polar/training_articles/improve_fitness/the_three_exercise_zones/exercise_zones
