Hi,
I can't find a calorie calculator that shows me how many calories Jackkives burn. Does anyone know this?

I wanted to do 300, but I wanted to know how many calories this will burn as an incentive to move and do it?

    isn't a jack-knife similar to a crunch/situp? I would log it as such...

    **EDIT - PS: Calorie calculators are based on time not quantity so you have to know how long it takes to do 300... a HRM is obviously going to give you the most accurate count, but you also need to determine your activity level (light/moderate/vigorous) when you do them
