Embracing supramaximal power

In the fast-paced world of fitness, where innovation meets performance, the CAROL Bike emerges as a game-changer, pushing boundaries and defying expectations. Are you ready to go beyond what you think you can achieve? The CAROL Bike is here to redefine your fitness journey.

The term "Supramaximal" takes fitness to new heights, transcending conventional limits. CAROL's groundbreaking approach utilizes your biometrics and performance data to unleash supramaximal power in every ride. Bid farewell to plateaus – CAROL ensures continuous progress and heightened performance.

Personalized resistance: the secret sauce

Recognizing that one size does not fit all, CAROL introduces the concept of AI (Artificial Intelligence) calculated personalized resistance. The magic lies in when and how fast fatigue sets in, all tailored to your unique profile. Brace yourself for a fitness experience like no other.

Get fit in 40 seconds – not 45 minutes!

Time is of the essence, and CAROL understands that. Scientifically proven to deliver the same cardiovascular benefits as a 45-minute jog in under 9 minutes, with a mere 40 seconds of intense effort. Say goodbye to prolonged workouts – CAROL optimizes your exercise time dramatically.

Personalized high-Intensity interval training (HIIT) mastery

CAROL's algorithms go beyond conventional HIIT workouts. They craft a personalized resistance plan to ensure you hit maximum power in every session, depleting your sugar stores effectively. No other fitness class or HIIT workout comes close to the precision of CAROL.

Your perfect workout, backed by science. 

CAROL is the world’s first Reduced Exertion HIIT (REHIT) exercise bike. With just 2x20-second sprints, our REHIT workout creates the most potent training stimulus. It’s scientifically proven to deliver double the health and fitness benefits compared to normal exercise in 90% less time.

How it works:

Warm-up 

Slow-pedal to prep for your first sprint – triggered by you any time after 20 seconds. 

Sprint 1 

AI applies the resistance you need instantly, so when you’re pushing hard, the glycogen in your muscles depletes – releasing signaling molecules. 

Recovery

It’s essential to recover well to get the most out of your next sprint – triggered by you any time after 1 minute. 

Sprint 2

The signaling molecules released in Sprint 1 switch on, telling your body to get stronger, fitter, faster. 

Cooldown

The cooldown brings your blood pressure, heart rate, and breathing back to normal. 

Get fit in 40 seconds. Well, that is 40 seconds of hard work - 8 minutes and 40 seconds total workout time!
