Ski Machine and XL Glider

I have both of these machines, but I'm not sure how many calories they burn. I tried searching for them in the database, but couldn't find either of them. If they are in the database, how are they listed? Is there a way to add them? I tried using my personal exercise, but it still has to search and find the machine. If I'm going to use them, I want to know the calories to be counted on my profile. :smile:

Thanks!
