What makes CAROL unique?CAROL bike features
DESIGNED BY SCIENTISTS TO DELIVER RESULTS
You want a special bike for special results
During a CAROL sprint, the maximum effort levels are roughly three times higher than in HIIT cycling courses. On a typical exercise bike, this kind of performance is unachievable.
You’d have to:
- Use the proper resistance (just in your sweet spot)
- In a fraction of a second, at the right time (just after you’ve built up speed at a low resistance) (instantly go from very low to very high)
- To put it another way, it’s quite tough to succeed without the help of an exercise physiologist.
It’s simple to conduct high-intensity sprints and achieve maximum performance on a CAROL bike.Simply go on the bike, log in, and the bike will guide you through two 20-second maximum intensity sprints (personalized resistance) interspersed with mild warm-up, recovery, and cool-down intervals.
DESIGNED BY ENGINEERS FOR GREATER QUALITY
Shorter, smarter workouts
You don’t have to be concerned with altering your resistance or keeping track of your production. CAROL takes care of everything for you, automating and leading you through each high-intensity sprint so you can concentrate on going all out.
The program learns your abilities, tracks your progress, and tailors each ride to push you to your limits. Our computer-controlled magnetic brake technology provides tailored and carefully calibrated resistance at precisely the appropriate time and rate.
CAROL has been certified to the most exacting standard for commercial-grade ergometers, and the bike’s sensors and algorithms will use CAROL’s patented Octane Score to properly assess your performance and fitness level.
CAROL will make it harder as you get fitter, and if you’ve been on vacation and aren’t where you were when you left, CAROL will make it easier.
Over the course of eight weeks, 32 individuals were divided into two groups to assess the effectiveness of CAROL’s workouts and compare them to current government exercise guidelines.
DESIGNED BY DOCTORS TO KEEP YOU SAFE
Safety in the saddle
CAROL’s ultimate goal is for people to have healthy hearts. CAROL includes an integrated heart rate monitor and built-in safety algorithms that will warn you or even cancel your ride if something unusual is noticed.
Scientists meticulously created and tested CAROL’s maximum intensity sprint routines to give you enough time to recover so that your blood pressure and metabolism return to normal after pushing to your intensity limits.
On a CAROL bike, you’re in good hands as you go all-out for optimum results. The commercial-grade frame can endure the most extreme forces, and the freewheel clutch allows for safe explosive sprints with quick acceleration and deceleration.

THE SCIENCE BEHIND CAROL 5 minutes workout – Science and technology combined
4 academic collaborations.There have been several peer-reviewed studies.An active research and development program, as well as a data science staff. CAROL pushes the boundaries of HIIT research in academia.
How does CAROL bike work?
WORKOUT WITH NTENSE:
Step 1 – Warm up
It takes 2 minutes. Slow pedaling will prepare you for the sprints.
Step 2 – Sprint
It just takes 20 seconds. Within 10-15 seconds of your initial sprint, your glycogen will be depleted, and chemicals that signal other changes will be released.
Step 3 – Recovery
It only takes 3 minutes. Recovery is critical for a successful second sprint.
Step 4 – Sprint
It just takes 20 seconds. The molecules released during the initial sprint are now triggered, resulting in a series of changes that result in a fitter, leaner, and healthier you.
Step 5 – Cool Down
It only takes 3 minutes. These three minutes lower your blood pressure and return you to “normal” after all of your hard effort. CAROL provides mindfulness breathing guides that will help you de-stress in minutes and get back to whatever you were doing.
Prioritize quality over quantity
CAROL combines science, technology, and artificial intelligence to provide you with the greatest outcomes in the shortest time possible. For a hectic lifestyle, this is the ideal scenario.
CAROL automatically provides the correct resistance at the right speed at the right time for your fitness level, based on the scientifically proven benefits of REHIT (Reduced Exertion High Intensity Training) and fast glycogen depletion.
As a result, maximal exertion levels during a CAROL sprint are roughly three times higher than in HIIT spin courses, and it provides more health and fitness benefits in a fraction of the time as compared to traditional exercise.
What is REHIT?Maximum vs. high intensity
In a nutshell, REHIT is the distinction between high-intensity training and maximum-intensity training.
It’s based on the idea that fewer, shorter bursts of maximum intensity create better results, and it uses two 20-second all-out bursts to swiftly drain your thigh muscles’ glycogen stores. Because you spend less effort than in regular HIIT sessions, the phrase Reduced Exertion High Intensity Training was coined.
Previously, the REHIT effect could only be achieved in a lab setting. You may now enjoy the benefits in the comfort of your own home, thanks to CAROL.
Since the release of the CAROL bike in 2024, it has been able to get the health and fitness advantages of a 45-minute run in just 8 minutes 40 seconds.
This brief, effective cardio workout is based on peer-reviewed scientific research into a time-efficient alternative to regular exercise known as low effort high-intensity interval training (REHIT).
Four years later, the newest CAROL bike update now allows you to get the health advantages of REHIT in just 5 minutes. That’s right, the most efficient and effective cardio workout just became much more efficient!
How does REHIT work?
The physiological underpinning of REHIT is that high-intensity exercise causes your body to enter fight or flight mode, raising its energy needs by a factor of 100. After all, your body has no notion you’re sprinting on an AI-powered exercise bike rather than fleeing a predator.
Because your body has no clue how long you will need to sprint, the increased energy demand forces your muscles to mobilize substantially more glycogen (stored sugar) than is really necessary for two brief sprints. This quick depletion of energy reserves triggers physiological adjustments that make you fitter and stronger. After all, perhaps the next time you’ll need to run even faster and further to avoid the ‘predator.’
Delve deeper into the science of muscle glycogen depletion
CAROL is the only exercise bike that provides true REHIT because its AI personalizes your workouts to ensure that you always reach your personal maximum intensity. Dr Niels Vollaard, a health and exercise science in sport researcher from the University of Stirling, explains it thus way:
“Outside of the labs, CAROL is the only system that accurately duplicates my research.” This scientific exercise cannot be performed on a standard bike because to the supra-maximal resistance necessary, which must also be customized to each individual’s physiology.”
The science behind the new 5-minute REHIT exercise from CAROL bike
This is the structure of the REHIT protocol utilized in CAROL’s initial 8-minute 40-second Intense ride:
- 2 minutes to warm up
- Sprint 1 – 20 seconds
- 3 minutes of recovery
- 2 – 20 second sprint
- 3 minutes of rest
According to research, the physiological impact of REHIT is derived from the highest effort sprint phases. That got us thinking: might we minimize the non-sprint periods without sacrificing overall health and fitness benefits?
Dr. Vollaard said, “The health and fitness advantages of REHIT are activated by two 20-second maximal intensity sprints.” The duration of the warm-up has no effect on the efficacy of REHIT.”
Thus far, so good. But what about rest periods in between sprints? “In order to get the maximum health and fitness advantages of REHIT, your recovery time between sprints must be sufficient to allow for a powerful second sprint.”
You’re thinking: how long is “long enough”? That is all up to you. It’s best to wait until you’ve regained your breath, but it may be anytime you’re ready to go all-out again.
The cooldown timer stays at three minutes. “It’s vital for blood pressure to equalize again after the race,” says Ulrich Dempfle, CEO and co-founder of CAROL. According to research, mild pedaling accomplishes this faster than simply sitting or standing. This is due to the fact that keeping the muscles active aids in pumping blood back to the heart and hastening the clearance of ‘waste’ products from the muscle, so minimizing the imbalance between the concentration of such particles inside and outside the muscle cell.”
To conclude, the health advantages of REHIT are found in the sprints at maximal effort. And, while a cooldown is necessary to ensure your body returns to normal before getting off the bike, warm-up time has no effect, and recovery phase duration is unique to you.
CAROL bike Rapid glycogen depletion
Survival of the fittest
The ‘fight or flight’ response is triggered by CAROL’s short maximal intensity sprints. This evolutionary
signal warns your body that in order to survive, it must adapt and become fitter and stronger.
Your muscles are forced to consume muscular glycogen – your body’s emergency energy reserve, which
is sugar stored in the muscle – as fuel due to the rapid demand for energy. Glycogen depletion boosts aerobic
capacity, resulting in increased fitness.
Two 20-second sprints by CAROL decrease glycogen reserves by 25-30%. You’d have to run for 45-60 minutes
to reach that level of fitness. CAROL AI bike is the simplest and quickest approach to drain glycogen and become fitter,
leaner, and healthier.
CAROL bike Results confirmed by research
ACE study-Get twice the gains of regular exercise
Over the course of eight weeks, 32 individuals were divided into two groups to assess the effectiveness
of CAROL’s workouts and compare them to current government exercise guidelines.CAROL’s eight-week
approach can lower your metabolic health risks by 62% and double your gains in all health and fitness
indicators.
A peer-reviewed study published by the American Council on Exercise (ACE) confirmed CAROL’s greater
results over typical exercise regimens .
You can get the following benefits by using CAROL bike for just eight minutes 40 seconds three times a week
for eight weeks:
– The risk of metabolic illness (MetS Z-Score) was lowered by 62%.
– A 12 percent boost in heart and lung fitness
– A 5% reduction in blood pressure
– Triglycerides (a type of fat found in the blood) were lowered by 10%.
– HDL (good cholesterol) increased by 6%.
– A 2% reduction in blood sugar
You’ll burn twice as many calories on CAROL bike for every minute you spend exercising than
you would with traditional workout. Because CAROL’s “after burn” burns twice as many calories after
your workout as it does during it, you’ll burn twice as many calories.
Improved insulin sensitivity, which helps you become metabolically flexible and access and burn
your body’s fat stores, has also been found to assist you in studies.
As a result, your rider’s high will endure long after you’ve completed your workout.

CAROL bike review – Using the CAR.O.L Bike
The Carol Bike is quite simple to use. You’ll need to register an account when you first get started, and you
may have one for each person in your house. Because there is no extra charge for this, unlike other models
that need a subscription-based payment plan, the Carol actually compares well in terms of long-term and
ongoing expenses.
You will be guided through an initial calibration session when you first use the device, and there are a total of
six of these sessions. Ours grew increasingly difficult, with only two 10-second sprints in the first couple of
sessions and two 20-second sprints in the next four.
This becomes the standard for your workouts, and the resistance and torque settings are monitored as a baseline
from this first six-session calibration, which is then changed as you work out over time.
There is a step-by-step instruction handbook as well as video tutorials available for setting up the CAR.O.L bike.
If you get stuck at any point throughout the assembly, there is a superb customer support team on hand to help you
out. Because you will require an Internet connection to set up the bike, the customer care staff may also assist you with
any setup difficulties you may have.
The CAR.O.L. is also very heavy to move about, weighing 59kg (just over 9 stone), and it has a maximum user weight
of 130kg (c20 stone), so it should be ideal for a wide range of users.
You’ll need to fill out some personal information during the first setup, such as your age, weight, and height.
The CAR.O.L. can personalize every exercise for optimal benefit by monitoring your biometrics in real-time and cross-referencing
the data the bike gathers with each activity.
The procedure begins with data collecting. This comprises of six introductory rides during which the bike assesses your existing
fitness and health levels in order to build a baseline, which it will then utilize to customise your development and training through
constant changes from the CAR.O.L. bike’s 1,000 resistance settings.
After you’ve finished the tutorial, you’ll be able to choose from seven distinct training modes:
- Intense
- Energiser
- Constant Power
- Fat Burn 30
- Fat Burn 60
- Continuous Ramp Up
- Free Ride
5-minute REHIT workout for Intense
- Get out on your bike and open the CAROL app.
- Select an intense ride.
- A checkered flag will show on the RPM dial from 20 seconds into the warm up to one minute into the recovery period.
- When you see the flag and feel ready, simply accelerate your pedaling to start the sprint.
Energiser
Instead of two 10-second sprints, this is a condensed version of Intense. It is meant to give your body a bit of a wakeup call, but
not completely zap the body, and is better suited for off days or to keep the body ticking along, as the name indicates.
Constant Power
Constant Power is a brilliant feature in which the CAR.O.L automatically adjusts the resistance to keep your chosen power. This is
accomplished by changing the resistance as your RPM varies. All you have to do now is keep pedaling, and the CAR.O.L. bike will handle the rest.
Fat Burn 30 and Fat Burn 60
If you want to reduce weight and burn fat, these training settings are great. A two-minute warm-up, 30 or 60 eight-second sprints
with 12 seconds rest in between each sprint, and a three-minute cool-down are included in these two exercises. This is a real beast of a workout.
Continuous Ramp Up
This training setting gradually raises power by one watt every three seconds, creating a long and grueling stamina test with the purpose of
increasing your VO2 max. As a result, to get the most out of this workout, use a portable VO2 max analyser to measure your progress.
Free Ride
If you want to travel at your own pace, Free Ride is available, similar to how traditional exercise cycles function. You may choose the level of
resistance and other objectives you want to reach before starting to cycle.
One thing I enjoy doing is keeping track of my development. This is crucial for remaining motivated and actually sticking to a fitness plan.
Every time you complete an exercise, CAR.O.L saves it so you can see how you compare to other CAR.O.L. bike users around the world on weekly
leader boards, as well as track your own progress. If you’re competitive like me, you’ll appreciate this function, which makes exercise more enjoyable.
The Peloton Digital platform is also integrated with CAR.O.L. This means you may have the best of both worlds in terms of furious solitary rides that incorporate all of the advantages of HIIT workouts, as well as classic free riding where you can participate in Peloton’s online courses.
It should be mentioned that in order to use this function, you’ll need a paid Peloton Digital subscription, so keep that in mind if this is something that interests you.
