Heart Rate Monitors

[halo518]

I recently purchased a pretty decent heart rate monitor, due to the strong recommendation by my trainer to get one. I have been plateauing for quite awhile now ... I believe this is partly due to not changing up my routine enough and not progessing with my weight training much. However, after going back to using a PTrainer, he has told me he thinks I am not eating enough. I have an extremely hard time believing this, I track every calorie I eat - I get in at least 1700 cal and as much as 2100. (I'm 28 y.o. female, 142lb.)

Anyway, here's the question ... my heart rate monitor (w/chest strap) allows me to put in my body weight and gender and then it will calculate calories expended. It seems to be pretty accurate (which I say because when it says my HR is 170 - 85% of my MaxHR - it actually FEELS like I am exerting about 85% of my effort). Anyway, the other day I put it on in the morning, and had it start calculating the calories I expended all day long. By the end of the day, it said I had burned 6500+ calories ... can this POSSIBLY be accurate??? I have a desk job, so I'm fairly sedentary most of the day. I did workout (10mins of cardio and 1hr lifting) on the day that I did this, but still ... 6500 calories seems impossible. Wouldn't that mean that as long as I'm eating 6000 calories a day, I theoretically should be losing a pound a week??? I know I've got to be missing something obvious here ... or maybe this calculator is just totally inaccurate?

Thanks!

what is your weight goal. Are you trying to lose weight or just get muscle.

From you lbs. You should be taking in about 1700 kcals a day to just stay where you are. That mean not gain or lose. But if you are trying to lose bring your kcals down to about 1300. But if you are trying to gain bring it up to what your PT said 2100.

And for that heart rate monitor I really think it was broken. If lost 6500 kcals in a day you wouldn't been here to day. That is alot of kcals lost in one day.
