Arc Trainer Tip: Constant Power vs. Adaptive Power

Exercisers have loved the Arc Trainer for years, but did you know about the advanced programming modes available on the Arc? Exercisers can use Constant Power and Adaptive Power to transform workouts, making them more focused and effective.

What is the difference between Constant Power and Adaptive Power?

Adaptive Power on the Arc Trainer is a mode where, rather than setting a fixed resistance, the resistance automatically changes in response to the user’s cadence. Specifically, increases in cadence are met with increases in resistance, and vice versa. The higher the level chosen (range from 1-25), the more aggressive the resistance increase.

The below chart demonstrates how cadence determines wattage based on the Adaptive Power level:

For example, a user in Adaptive Power level 5 at 150 steps per minute experiences about 200 watts. We describe this mode as accommodating resistance because it responds to you – if you feel good, push the pace and you’ll experience a higher wattage. This makes Adaptive Power perfect for high-intensity interval training.

Constant Power also behaves by automatically changing the resistance in response to user cadence. But in Constant Power, increases in cadence are met with decreases in resistance. This is to maintain a constant wattage – which is determined by both resistance and speed. Constant Power is a great program for exercisers who want to maintain a constant intensity throughout the workout, because the machine automatically adjusts any time you increase or decrease your cadence.
