Q: Why is CAROL different from other bikes?
Reduced Exertion HIIT (REHIT) and AI-personalization make CAROL Bike unique. Developed with leading exercise researchers to give you the shortest, most effective workout.
REHIT is the next-level HIIT workout that gives you double the health benefits, in just 10% of the time. CAROL Bike’s signature REHIT workout can be done in just 5 minutes. And it’s proven to be the most effective cardio.
Q: Is the 5 minute workout enough to lose weight?
With CAROL’s signature 5-minute workout you’ll burn twice as many calories minute-per-minute vs. traditional cardio, thanks to afterburn, which lasts for up to 3 hours after you ride.
Ulrich details new research by ACE (American Council on Exercise) that shows you’ll burn more calories on a 15-minute CAROL Bike ride, than a 30-minute run.

Q: How do you suggest integrating CAROL with strength training?
Gym owners have relayed to Ulrich that their clients do strength training before their CAROL workout, and avoid leg work on CAROL days.
While there is no clear research on integrating CAROL with strength, Ulrich recommends experimenting to find your perfect regimen.
Q: Can I improve my VO2max with CAROL?
VO2max is the main measure of fitness. The higher your VO2max, the fitter and healthier you are.
Ulrich references the scientific study which proved CAROL’s signature REHIT workout can improve your VO2max by 12%, in just 8 weeks.
Q: Can I do REHIT workouts without CAROL?
REHIT was developed by scientists looking for the shortest, most effective and accessible way to exercise. Research proved that REHIT is the fastest way to get fit, but there was a catch: true REHIT was only possible in the lab.
We teamed up with the world’s leading exercise researchers to get REHIT out of the lab—into the real world. CAROL is the only way to safely and effectively recreate REHIT, thanks to AI-personalization and Instant Resistance.
Ulrich suggests the next best thing—all-out sprinting on a running track—but this comes with safety risks.
