I've heard that you don't start burning calories until yu've worked out for like 30 minutes. Is that true?

i think you are confusing it with something else. Im pretty sure one time I heard that you dont start burning FAT until about 30 minutes of cardio. Am I wrong on this? idk for sure

that isnt true just sitting around burns calories but you do burn more effective calories when you do work out for thirty minutes...if you want to know how many calories you burn doing different actvities go to www.caloriesperhour.com
