Orbitrek elite/ Elliptical for resistance training??

thoyamma

I have an Orbitrek elite (its an elliptical machine) at home. Thats the only workout I do other than walking for one hour twice a week. I want to know if Orbitrek's rowing motion gives some kind of resistance training. I want my arms to be toned. does this help at all? and if anyone uses the orbitrek with a heart rate monitor, can you please tell me if the calories burned shown on the machine are anywhere near to accurate? Thanks a lot.
