Indoor Smart Bike First To Introduce AI-Personalized REHIT Workouts

“The CAROL Bike Is Scientifically Proven To Deliver Superior Health and Fitness Gains in 90% Less Time”

New York, NY / Aug 30, 2023 / CAROL Bike

Designed to revolutionize how we approach fitness, the CAROL Bike is an AI-enhanced exercise bike that gives you the shortest, most effective workouts in 90% less time compared to regular cardio – while delivering double health and fitness benefits. CAROL’s AI-personalized workouts are easy to follow, suitable for any age and fitness level, and create the most potent training stimulus with just two 20-second sprints. With a gentle warmup, recovery and cooldown, users are able to complete a workout optimized for their fitness level in as little as 5 minutes. The approach marks the first time a fitness product is able to offer consumers a Reduced Exertion High-intensity Interval Training (REHIT) workout outside of a scientific lab.

The CAROL Bike, which stands for “Cardiovascular Optimization Logic,” was developed by co-founder and CEO Ulrich Dempfle with leading scientists (including Dr. Neils Vollaard and Professor Lance Dalleck). Through Dempfle’s previous experience running chronic disease management programs for patients with heart conditions and diabetes, Ulrich wanted to create a way to make cardiovascular exercise more accessible and efficient for everyone. “There is no denying that cardiovascular exercise is one of the most powerful tools we have to prevent chronic diseases,” says Ulrich. “However, getting more people to exercise regularly has always been a challenge. The CAROL Bike aims to take away those barriers to offer a workout that’s less time consuming and more effective.”

He adds, “With CAROL’s signature workouts you’ll burn twice as many calories minute-per-minute versus traditional cardio, thanks to afterburn, which lasts for up to 3 hours after you ride.” The workouts help you develop more mitochondria, and increase your blood plasma volume, boosting your heart health. Additionally, research proves that just three short CAROL Bike workouts a week can help lower your blood pressure, reduce your risk of type 2 diabetes, decrease triglycerides (fat found in blood), and increase good cholesterol (HDL).

The CAROL bike is scientifically proven to improve your VO2max by 12% in just 8 weeks, reducing the risk of mortality and morbidity.  VO2max measures the maximum amount of oxygen you can burn while working out: the fitter you are, the higher it will be. The AI personalization means the bike adapts to users of all fitness levels, from beginners to advanced athletes.

Riders can choose from 20 scientifically-proven workouts and fitness tests, stream content via Netflix, connect other cycling apps, and have access to  a community of over 20,000 riders including wellness gurus like Dave Asprey, Ben Greenfield, and Dr. Michael Gervais. The bike retails for $2,595, and is available for purchase on
