“CAROL is the only system that accurately replicates my research outside of the labs.” Dr. Niels Vollaard

The maximum intensity levels during a CAROL sprint are about three times higher than in HIIT cycling classes. It is impossible to perform at this level on a regular exercise bike.

You’d need to:

• Apply the correct resistance (just in your sweet spot)
• At the right time (just after you’ve built up speed at a low resistance)
• In a fraction of a second (instantly go from very low to very high)

In other words, it’s very difficult without an exercise physiologist by your side.

To perform maximum intensity sprints and get maximum results on a CAROL bike couldn’t be easier.

Simply get on, log in, and the bike will guide you through two 20-second maximum intensity sprints (personalizing the resistance to you), in between gentle warm-up, recovery, and cool-down periods.

You don’t need to worry about changing resistance or tracking your output. CAROL does it all, automating and guiding you through each maximum intensity sprint so you can just focus on going all out.

The software learns your ability, measures each performance, and adapts each ride to push you to maximum intensity. Our computer-controlled magnetic brake system applies a personalized and precisely calibrated resistance at the exact right time and pace.

CAROL has been certified to the most accurate standard for commercial-grade ergometers and the bike’s sensors and algorithms will quantify precisely your performance and fitness level through CAROL’s proprietary Octane Score.

This means that as you get fitter CAROL will make it harder and if you’ve been on holiday and aren’t where you were when you left, CAROL will make it a little easier.
