Elliptical pedals can be cushioned and adjustable for maximum comfort and minimum impact on joints for injury prevention.

Some elliptical trainers can be set at an incline to increase difficulty and burn more calories.

15° - 40° Elevation Range

The flywheel controls the smoothness and resistance of your workout. In general, the higher the better.
