Cybex Advice

ecove

My gym has some Cybex arc trainer machines (without the moving arm part). I tested them out one day last week using the Interval setting on Level 2 and didn't mess with the incline aside from that and almost died before finishing my 30 minutes. I was hoping I'd burn more calories but I only burnt 300 -- the same as what I burn when I do 30 minutes on the elliptical.

Does anyone have any tips for arc trainer settings so I'll actually burn more? What program, level, etc settings do you recommend?

TIA!!
