862 calories burned... is this possible?
I bought the FT40 Women's HRM and I'm loving it so far, but I don't know if I can trust it. Stats: Female 5'3.5" 150lb 22 years old I just worked out for 80 minutes and it said I burned 862 calories. I do intervals and when I'm running my heart rate maxed out at ~193 (just for the last minute) but stays between 160-180…
