Workout Intensity: 

The harder you pull, the more resistance you will feel. This is because the AirSki uses air resistance, which is generated by the spinning flywheel. The faster you get the wheel spinning, the more resistance there will be. You can ski as hard or as easily as you wish, the AirSki will not force you to ski at any set intensity level.

Damper Settings:

The AirSki features a spiral damper with settings from 1 to 10. The damper setting is like a bicycle gearing. It affects the feel of the skiing but does not directly affect the resistance. By changing the damper setting, you can simulate the range of skiing speeds that occur on snow. Higher numbers feel more like skiing in slow conditions or uphill. Lower numbers feel like skiing in faster snow conditions, on flat terrain and downhill. For general fitness and a good aerobic workout, use a damper setting between 1 and 4.
