So, I got my new heart rate monitor on Monday and have been testing it with various exercise activities I do.
I'm wondering if it's actually accurate and looking for comments from other folks that use one.
I have been estimating, based on SP's calculator and other online calculators, that 1 hour of Jazzercise, for instance, burns about 450 calories for a high intensity session. While wearing my HRM yesterday and today, I had "calories burned" reported at 864 and 906 for the 1 hour session. I was working moderately hard, within what I consider to be an acceptable beats per minute zone.
This seems to be really off from what the calculators I've been using have reported.
It makes me wonder, have I been underestimating my burn all this time and thus, under-eating when I was in a losing weight program, putting myself in to starvation mode? It could certainly explain a lot.
I posted a link to the model I purchased in my last blog - it's a Timex Ironman Digital Zone HRM.
So, I would love to get some thoughts on this. Do you use a heart rate monitor? Do you think they more accurately estimate your true calorie burn for exercise? Thanks!
