My elliptical has the moving arms so that helps give more of a full body workout for me. I can't do the ellipticals that only the legs move on a tract, too up & down for me and heck on my hamstrings. I'd say just start out slowly with resistance at 1. After 5 minutes, see if you can increase the resistance a notch. Gradually increase every 5 minutes, etc. until you reach the goal you've set for yourself. Considering it's all about getting your heart rate up, if you can only keep resistance at 1 or 2, just get your speed up until you're feeling stronger and muscles are adjusting to the new routine of working out. I've worked my way up to resistance 15 and start at 1...I increase resistance every 2-3 minutes and it keeps me from getting bored (mentally & physically)! Good luck and keep up the good work!!!
