How do you figure out how many calories you've burned doing

Terriberry

I have the Biggest Loser Cardio workout video and don't know how to figure out how many calories I burn doing it. Any suggestions?

Maybe in one of the aerobics categories?

i'm not familiar with that particular work out but i just look up an activity that is the closest and use it. like dancing or stepping, aerobics, walking, whatever.
