Which cardio burns the most calories?

This might suprise some, but the best cardio for overall calorie expenditure is High Intensity Interval Training (HIIT). A basic example of high intensity interval training would be a 30 second sprint on the bike followed by 30 seconds of rest. Repeat this for 15 minutes. HIIT is more intense and takes alot less time than traditional forms of carido jogging do. The reason it burns more calories is due to a process called EPOC. EPOC stands for excess post-excerise oxygen consumption. EPOC sends an individuals metabolism through the roof leading to extra calories been burned not only during your workout but for up to 48 hours after! In simple terms this means that you worked your body so hard that you managed to create a debt that your body has to pay off in the form of consistently burning calories for an extended period of time. Next time you think of buring lots of calories stick to HIIT the key is short and intense!
