Ulrich Dempfle built on his background in mechanical engineering to develop the world’s only Reduced Exertion HIIT (REHIT) bike, alongside leading exercise researchers. Ulrich leads on product development at CAROL—from data science to software and hardware.

Q: What inspired you to make CAROL?

Ulrich co-founded CAROL to make optimal health and fitness easier to achieve for everyone.

Ulrich was not part of the fitness industry. He worked in healthcare with British health services, where his team designed and ran Chronic Disease Management programs for people with heart conditions and diabetes.

Exercise was one of the most powerful interventions, the only catch is: people don’t do it.

Then in 2012, Ulrich saw a documentary that showcased the most effective and efficient cardio workout: Reduced Exertion HIIT (REHIT). It was love at first sight. The only problem was, you could only do it in a lab.

Since then, CAROL has launched the world’s only REHIT exercise bike for home and gym use.

Q: What are you most excited about for CAROL at the moment?

Ulrich is excited about launching CAROL Bike 2.0, designed to maximize training efficiency—with workouts backed by science.

CAROL Bike 2.0 has new rider-inspired features that give you more flexibility, to exercise your own way. Including handlebars with 5 grip positions, so you can mix up how you ride, and a wearable heart rate monitor to track your performance more accurately—and free up your hands while you recover or refuel.

Q: Do you have any fitness goals you're working on right now?

Ulrich may use CAROL every day, but studies show it only takes 3 rides a week, for 8 weeks, to improve your cardio fitness by 12%, reduce your risk of type 2 diabetes by 62% – and your blood pressure by 5%.

Q: Where are you personally on the CAROL leaderboard?

Thanks to CAROL Bike’s shortest, most effective workouts, Ulrich built a fitness habit that took him from the middle of the leaderboard—to the top 10.
