Calories Burned on 30 Day Shred
I recently purchased a Polar F7 hrm and am shocked to see how low my calories burned have been, for both cardio work at the gym and home dvd's. For example, my hrm says that I burn only 136 calories when I do the 30 Day Shred. For as much as I sweat it seems like I should be burning more. Anybody else have the same thing…
