Reduced Exertion HIIT (REHIT) training explained

How to upgrade your fitness program and increase fat loss with CAROL—the world’s only home REHIT exercise bike—according to Mike Mutzel.

Mike is a Functional Medicine Consultant, Author, Podcaster and YouTuber with a MS in Human Nutrition. He explains why you should use power as an objective measurement to inform your cardio training—and why CAROL Bike is the perfect way to do so.


Mike recommends using power to guide your cardio workouts—because it is objective. Other metrics such as calories, heart rate and duration can change, making them an inefficient guide for progression.


CAROL Bike’s AI-personalization ensures you’re constantly progressing—by customizing the power goals and thresholds during your workouts.


Mike also recommends REHIT workouts for their efficiency. Short, high-intensity training is a lot more efficient than long steady-state workouts—with far greater benefits.


CAROL Bike gives you the shortest, most effective workouts—backed by science. With AI-personalization that learns to push you to your limit, CAROL’s the only bike in the world with REHIT.

“Short high intensity workouts are way more time efficient. You’ll have to do a 45-minute run to get the same benefits.”
