So I tried an elliptical for the first time a couple days ago, mainly because it was too hot outside and the other machines were being used. I was always under the impression that they are easier to use than treadmills or stairmasters. Strangely, I got very fatigued after only about 5 minutes on the elliptical. Does anyone else have this experience that the elliptical wears them out quickly? For some reason I felt I was working much harder than with other activities and ran out of breath. Before anyone states that I am out of shape, for reference I routinely run 5-7 miles 3-4x/week at 7-7:30 pace, sometimes use the stairmaster at 120-140 steps/min w/o a problem, so I think my conditioning is decent.
