Co-Founder Q&A: Good habits start here

From how to maintain your cardio on vacation, to the best way to build a fitness habit, CAROL’s CEO and co-founder, Ulrich Dempfle, answers habit-based questions from our social community.
Ulrich Dempfle co-founded CAROL to help riders form a simple, effective fitness habit that fits seamlessly into their day. Here he shares his top tips for setting lasting fitness habits.

Q: I need to exercise more. What would you recommend to do to build a fitness habit?

Ease of adherence is key for setting a lasting fitness habit, so Ulrich recommends finding what works best for you. Which could mean doing 15-second sprints instead of 20-second sprints on your CAROL Bike, or training in the morning rather than evening. Once you have your perfect regimen, you can get to a point where you don’t even have to think about it, and adherence will become second nature.

Q: What advice would you give to maintain your cardio when you are on vacation?

By focusing on short, impactful workouts, like HIIT, you are more likely to maintain your cardio while on vacation. Ulrich’s go-to is going for a jog, and interspersing it with short hard bursts.


If you have the time, Ulrich recommends getting outside and making the most of your environment. Go for a walk. Play tennis with a friend. Rethink how you define ‘a workout’, have fun with it—and don’t be too hard on yourself.
