Q-factor isn't something a lot of people are familiar with, but you absolutely should be if you're looking at any sort of cycling equipment. Basically, it's the distance between the pedal attachment points, and the pedals themselves. Everything needs to line up so that your feet, ankles, knees and hips are aligned. That way, you avoid any sort of stress and strain and an eventual pull or strain from having your body out of alignment while you're pushing. This Elliptical has the pedals arranged in the correct Q-factor for good health and a good workout. And not every Elliptical, or bike, out there does.
