If you are roughly a 180 pound man give or take say 10 pounds, cardio machines are a fair accurate indicator of calories burned. If you are say 160 pounds and below or 200 pounds and above cardio machines can be inaccurate to measure how many calories you have burned. A person who weighs more travelling at the same speed as a person who weighs less will burn more calories.
