I worked out for 20 minutes on the elliptical at the gym tonight. It's the kind where you put in age and weight. I was working on level 7, I think it was. Not sure out of how many. I was going about 100 strides per minute, on average. Sometimes more, sometimes less. It showed that I burned 135 calories in 20 minutes.
Oh, and I weigh 138 and am 23 (almost 24), if that helps.
