I understand where you are coming from. I am also addicted to the eliptical trainer. I do 60-70 min 5 times a day and people always tell me I shouldn't do it for so long or that I should change it up some. I agree that I am in a comfort zone...but I am exercising and I do change the program I am doing...plus I will also add some interval training to it...maximizing my speed for 3-4 min then slowing down. The way I see it is....I am exercising and that is more than I was doing before (which was nothing!)....if this works for me-then why is it wrong?
