I have been using myfitnesspal.com to keep track of my calories to ensure that I'm losing weight, but I don't really know how to see how many calories that I'm burning with my exercise. I am doing CF, hiking with weights, running, sprinting, and general weightlifting, but I don't know how to measure the calories that I'm burning to ensure I'm burning more than I'm taking in. Is there something I can do to find out? Hope that isn't a stupid question.
