Manual Heart Rate to Calories Burned Help.

Liedx

Hello. I am very new to this and quite dumb that I can not figure this out on my own.

I exercised for a total of 40 minutes this morning doing elliptical, weights and a 15 minute walk. On the elliptical it said my resting was at 64bpm. As soon as I got home I pulled out the timer and counted my bpm. It was at 133bpm. Now, I checked as soon as we got back.

So, I am trying to roughly figure out my calories burned as I do not think MFP is accurate.

Um...

Height: 5'6"
Weight: 135
Age: 23


Thank you.
