Cardio Calories

How many calories are you actually burning on those cardio machines in the gym? Can you be sure that when you get off the elliptical machine you can feel elated that you burned off last night's cheeseburger and fries? Well unless you enter in your own age, gender and body weight into your machine your calorie count will automatically be based on a 150 pound man. All you 150 pound men can rest easy (I have a feeling to weigh 150 most of you are still in high school), but unfortunately for everyone else you've probably been over estimating you calorie burn, bummer I know. So make sure you enter in your real weight and age when you get on the cardio machines then you can know last night's cheat meal is no big deal!
