The Air Rower delivers strong resistance with a clever combination of air and magnets. This means the resistance level can be increased or decreased, making it suitable for all levels of users, but also capable of delivering a killer workout! The performance monitor has a single, large, screen so you can see all your workout data with a quick glance, and it tracks all the data points you'd expect; time, distance, calories, watts, strokes, SPM and time/500.
