The science behind the CAROL bike

Developed with leading exercise researchers, CAROL Bike delivers the shortest, most effective workouts using its signature REHIT method, featuring 2×20-second sprints. Scientifically proven to provide superior health and fitness benefits in 90% less time than regular cardio, CAROL’s AI-personalisation helps push your limits during sprints. This triggers a ‘fight or flight’ response, forcing muscles to mobilise 25-30% of glycogen reserves, releasing key molecules like AMPK and PGC-1a. These signals lead to increased fitness by boosting mitochondrial development, blood plasma volume, and heart strength, resulting in enhanced aerobic and anaerobic capacity.

Process & experience

The CAROL Bike experience is all about efficiency and personalisation. When you start your workout, CAROL’s AI algorithms quickly assess your fitness level and tailor each session to match your capabilities. The workout involves two ultra-short, 20-second sprints that make up a part of the signature Reduced Exertion High-Intensity Interval Training (REHIT) method. These sprints are followed by periods of light cycling, ensuring that your body gets maximum results in a fraction of the time. The entire process is smooth, time-efficient, and designed to push your body to its limits, triggering an impactful ‘fight or flight’ response that helps improve fitness levels rapidly. CAROL’s system makes sure that even if you’re short on time, you leave the session feeling accomplished and well on your way to enhanced fitness.
