A little warning.
The Courtyard by Marriott has a very nice and expensive elliptical trainer. I got carried away and tried to see the maximum wattage I could sustain for one hour. I did not record the exact number but it was well over 1000 watts.
I suffered knee problems afterwards which I have never had before. I stopped doing that and went back to spinning on a bike trainer. The knee problem disappeared but it did scare me.
