Accuracy of Cardio Machines
I'm just wondering if anyone knows the accuracy of the calorie counters on cardio machines. I've been back at it a month now, and do 45-60 minutes on the eliptical cross trainer and it constantly tells me I've burned anywhere from 600-850 calories a workout. I'm wondering if this is even close to accurate.

They're not great. There are too many variables that are not considered when it is determining the number of calories you burn. Your bodyfat, amount of muscle, metabolism, etc. are not taken into account and these are all important factors.
At best it is a VERY general estimate, but one that shouldn't be relied upon if looking for great accuracy.

You will have to use a metabolic equation to get a caloric expenditure~

I talked to one of the gym attendants today about this. This guy claims the machines are accurate within 10% of the correct body weight is entered in. So in my case if I was vain and entered 275 instead of my actual weight of 290 it would completely screw me on the count. I very much appreciate the answers here though. The weight has been flying off of me though so I'm burning enough. That's what's important.

I dont know about them. 15 minutes hardcore on a bike claims I burned 80kcal. If I do the same time on the stairmaster it claims I burned 250-300kcal. The stairmaster is more exhausting. But can there be a 200+ kcal burned difference betwen the 2
