Calories burned much higher the POLAR HRM

KristianaRouth

I use MFP primarily to log my exercise. I've been logging my exercise from Jazzercise classes for the past 9 months. Today, I started using the Polar FT4 HRM. My 44 min. workout logged 416 calories burned...many times I had to slow down due to being way over my target heart rate (I'm 6 months pregnant, so I want to be careful not to go overboard). That being said, when I entered my exercise on MFP, the calories burned were over 600; more than a 200 calorie difference.

Any thoughts? I obviously am leaning toward the Polar HRM to be more accurate...but I was curious about what others thought about excessively high calories burned on MFP. Also, any thoughts about target heart rate and pregnancy during working out?

Yes, use the # from your HRM, MFP's #'s are notoriously inflated.

Use Polar HRM it is more accurate, I have a big difference between what MFP says and what my HRM says!
