everything you wrote makes perfect sense, and i think a lot of people would agree. I myself agree with you. theres no reason you cant do interval training on an elliptical; actually thats exactly what i did. also, i used to put the resistance WAY up (like out of 20, i would warm up on 12 and work at 15-16, doing intervals of hard sprints at 18-20). much better workout than a treadmill, and ironically gets some resistance work per your article. to nicknasty: i didnt mean to tell you that xyience flat out didnt work. what i said is that there are more efficacious and cheaper products out there. basically youre overspending for an inferior product. but of course, if youre happy with it, keep at it man. the most important thing is for you to be satisfied and stay motivated.
