The Concept2 rower is more affordable and has a higher weight capacity than any of the three NordicTrack models. It uses air resistance, which increases or decreases based on your effort (you can also adjust the airflow using the damper wheel). On the other hand, some people may prefer NordicTrack rowers because they all include a touch screen and offer additional features, such as streaming classes and auto-adjusting resistance. They also use magnetic resistance, which tends to be quieter than air resistance.
