How accurate are calorie counters on exercise machines?
Calorie counters on exercise machines are a rough estimate and that is all. The amount of energy you expend while exercising depends on a large number of factors, from one person to another, that these computers do not take into account. Even things like the humidity of where you are exercising and how good your current form is makes a difference. They also have a tendency to over estimate for the unfit and under estimate for the very fit. Use the computers as a guide from one session to the next but don’t treat their readings as bang on accurate… because they’re not.
