i need to find how many calories i lose from cardio, but does it also depend on heartrate. let's say my heartrate is in the 130 - 140 for my jog, and i jog for 1 hour 30 minutes. i want to ask if my heartrate also affects how many calories i burn, or does it only calculate your weight and what ur doing cuz as long as my heartrate is at a certain number, that means how many calories i am burning right.
There's no way to calculate it to an exact number, that and everyone is different. Lots of places on the web can give you a round figure for activity, take it all with a grain of salt this isn't an exact science.
