So from what ive read i gather the HRM is really designed to measure cardio burns. If you use it for weight lifting etc (like at they gym with dumbells and using the weight machines) it over estimates. I keep reading this everywhere i look! So my question is what do you guys log it as..... If you use it do u estimate it as half? or what? Im wanting to log it but i dont know how much it over estimates. anyone know? Btw... i love my polar :P

    I'm curious too. I wear my Polar for the entire time I'm in the gym. I start out with 35-45 minutes of cardio, then head for the weights, and go hard for another 30-45 minutes. I wonder if I should lower my polar number when I log it here...

    I use the Polar FT80 and it is made to use during weight lifting. I typically find it shows about half the calories of a low heart rate cardio session (50-60% of max heart rate) for the same amount of time.

    I use the Polar T31 (was decent when I bought it I think) - and my assumption was always that any "over-exaggeration" of calorie burn that it showed would be evened out by the fact that strength training burns more calories throughout the day as the muscle breaks down and is re-built. So if I lift for 20 minutes and the HRM says I burned 200 calories, even if I only burned 125, I would assume that over the course of the day, my body will burn an additional 75 calories more due to what it needs to rebuild muscle.

    I may be WAY off base here - but that is how I interpreted it!
