1 hour 23 minutes of weight lifting only 471 calories?

Yet elliptical would be like 1400 for that same amount of time? What? I don't believe it, I was winded and working up quite a sweat for my 83 minutes of weight lifting today/weight machines. It is so general. And there are many different types of elliptical machines, different heights/different resistance. I mean someone doing elliptical at level 1 is not going to burn as much as someone as level 25.
