Do you want to shed some pounds?CAROL bike weight loss method burns more calories after you get off the bike than it does when you’re riding. Insulin sensitivity improvements allows you to become more metabolically flexible and efficient at burning fat for fuel.

1 HIIT session, 6 CAROL protocols, ongoing upgrades, and interfaces with other fitness applications CAROL’s individualized exercises are designed for you, no matter what you wish to achieve.


CAROL bike is an AI-powered workout bike that enables users to attain maximum fitness improvements in the shortest amount of time.

REHIT, or Reduced Exertion High-intensity Interval Training, is used on the CAROL cycle. REHIT (Reduced-Intensity Interval Training) was created as a time-saving alternative to standard HIIT (High-Intensity Interval Training) and moderate-intensity exercise. It’s a scientifically confirmed workout that allows you to reach peak fitness in just 5-minute REHIT workout .

The CAROL bike employs artificial intelligence to personalize your workouts, allowing you to achieve your fitness objectives faster. CAROL’s AI can compute the exact resistance that will challenge you to your limits while never pushing you beyond them. CAROL’s AI adapts as your fitness improves over time, ensuring that you’re constantly working to your full capacity.

You may choose between a 30 sprint (15 minutes) or a 60 sprint (25 minutes) cycle that generates a large ‘after burn’ and has been proved to help you lose nine times more fat than ordinary exercise. Eight-second sprints at customized resistance are followed by 12-second rests in both choices.

The muscles burn up to a third of their sugar stores during the specifically tailored sprints, triggering an alarm response that causes the muscles to quickly “re-fuel” by pulling glucose from elsewhere in the body. Insulin is required for this. Our bodies become extremely sensitive to modest levels of insulin over time, allowing us to respond magnificently. After as few as six sessions, insulin sensitivity has improved by 25%.

Insulin is both a “sugar mover” and a “fat blocker,” thus the more you have, the less likely you are to burn fat. Because we have less insulin, our systems burn fat more efficiently rather than storing it.


This form of HIT also boosts mitochondria, your cells’ power plants. More of them means your body burns fat for longer, not only during exercise but also for hours afterward. Your metabolism speeds up as your body prepares to become a more efficient metabolic machine.

CAROL also boosts your body’s energy requirements even after your workout is finished. Because your muscles can’t obtain enough oxygen to complete the task they need to do during sprints, they switch to anaerobic metabolism (energy production without oxygen). There is a “oxygen debt” as a result of this.

Your body continues to burn calories for hours later to replace and recover to normal (pre-CAROL). With high-intensity exercise, this impact is substantially stronger.A CAROL exercise burns 66% of the calories that riders burn. When compared to typical exercise, which only burns 10-20% of calories, this is a significant difference. CAROL’s REHIT training (the Intense ride) and HIIT workouts both have an afterburn impact (the Fat Burn rides).

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:

  • Warm up – 2 minutes
  • Sprint 1 – 20 seconds
  • Recovery – 3 minutes
  • Sprint 2 – 20 seconds
  • Cooldown – 3 minutes

According to research, the physiological impact of REHIT derives from the highest intensity sprint intervals. That got us thinking: might we minimize the non-sprint periods without compromising overall health and fitness benefits?

When I asked Dr. Vollaard about it, he said, “The health and fitness advantages of REHIT are activated by two 20-second maximum intensity sprints.” The length of the warm-up has no effect on the efficiency of REHIT.”

So far, everything has gone well. But what about the time in between sprints to recover? “To reap the full health and fitness advantages of REHIT, you must rest long enough between sprints to allow for a powerful second sprint.”

We understand your concern: how long is “long enough”? It’s all up to you. It’s often a good idea to wait until you’ve caught your breath, but you may do it whenever you’re ready.

The three-minute cooling time is still in effect. “It’s vital for blood pressure to equalize again after the race,” says Ulrich Dempfle, CEO and co-founder of CAROL. Light pedaling, according to research, does this faster than simply sitting or standing. This is because keeping the muscles engaged helps to return blood to the heart and speed up the elimination of ‘waste’ products from the muscle, minimizing the imbalance between the concentration of such particles inside and outside the muscle cell.”

To recap, the maximal effort sprints are where REHIT’s health advantages reside. While a cooldown is necessary to guarantee that your body returns to normal before getting off the bike, the length of your warm-up has no bearing on the length of your recovery period.

CAROL can help lower blood pressure and increase metabolism for weight loss

There are many benefits to CAROL – double the health and fitness gains of regular exercise, maximum results in minimum time, and personalized workouts tailored to your ability to name but a few – but today we’re going to focus on the positive effects CAROL can have on your blood pressure and metabolism.

A quick look at blood pressure

On a typical weight reduction journey, a regular exercise regimen is an efficient approach to reduce your blood pressure. Physical activity strengthens the heart, allowing it to pump more blood with less effort, according to the Mayo Clinic. When your heart has to work less to pump blood, the force on your arteries is reduced, lowering your blood pressure. Increased resistance in the arteries forces your heart to work harder to deliver blood to your extremities and important organs, resulting in high blood pressure. When blood cannot flow freely through the arteries, they get hardened and finally obstructed, resulting in a blood clot. Once this happens, you’re at risk for metabolic disorders like diabetes.

Why CAROL is the quickest way to lower your blood pressure

One of CAROL’s most impressive features is her capacity to optimize the blood pressure of her users, being the most advanced and effective AI-powered home exercise bike of our time. Of course, other activities can help you decrease your blood pressure, but unlike typical time-consuming physical exercise, CAROL is a quicker and more efficient option. CAROL’s interval-focused (very) high-intensity activities can lower blood pressure far more quickly than traditional exercise. On a CAROL bike, you drain glycogen reserves in your thighs by performing two 20-second sprints at full effort. This sets off a chemical chain reaction – also known as a’metabolic signaling pathway’ – that improves cardiovascular fitness and, as a result, leads to a healthier you. An independent research undertaken by the American Council on Exercise (ACE) with the assistance of Dr Lance Dalleck, PhD showed scientific proof of blood pressure decrease among CAROL riders. The study found that taking a CAROL ride three times a week for at least eight weeks can lower linked health risks by an astounding 62 percent, compared to only 27 percent if you were running or other leisure exercise. This type of exercise lowers the chance of artery hardening and underlying disorders that might emerge as a result of high blood pressure, such as hypertension.  Studies have also repeatedly shown that high-intensity interval exercise is the best form of exercise if you are trying to lower your blood pressure – more so than traditional cardio, which has been found to have a much lower effect.

A quick look at metabolism

Exercise is a great way to increase metabolism, but after a workout metabolism ultimately returns to baseline levels. The elevated metabolism following exercise is referred to as excess post-exercise oxygen consumption, or EPOC. EPOS is also sometimes referred to as the afterburn. A new study finds that REHIT performed on a CAROL Bike boosts post-exercise metabolism twice as much as traditional exercise. The findings, which were recently published by the American Council on Exercise (Quantifying EPOC After REHIT, by Lance C. Daleck, PhD, Aidan M. Dalleck, and Bryant R. Byrd, MSc with Daniel J. Green, August 2021), are significant because a meaningful increase in EPOC (excessive post-exercise oxygen consumption) over the long term can have a significant impact on calorie expenditure and help people achieve weight loss and weight maintenance, as well as improve. The study compared the metabolic reactions and EPOC to moderate and intense treadmill workouts to shorter, REHIT (reduced effort high intensity training) rides on a CAROL bike, which was first published in the peer-reviewed International Journal of Research. Overall energy expenditure of a REHIT session on a CAROL bike, i.e. calories burned during exercise and calories burned via EPOC after training on the CAROL fat burn ride, was more than 2.5 times greater than vigorous intensity treadmill exercise, according to researchers at Western Colorado University’s High Altitude Exercise Physiology Program, led by Lance Dalleck, PhD. EPOC was two times higher after the CAROL 8-minute and 40-second hard bike than it was after moderate-intensity treadmill activity. “Exercise guidelines frequently talk about the benefits of exercise being tied to energy expenditure,” says Lance Dalleck, PhD. “However, it’s important to understand that energy is expended both during and after a bout of exercise.” One of the methods that shorter REHIT exercises can elicit equivalent effects to regular moderate-intensity exercise of a longer period is shown in this study.”

Why is EPOC important for weight loss?

EPOC is caused by a variety of circumstances, according to research, and it can play a key role in both weight reduction and weight maintenance. EPOC accounts for around 10% of total energy expenditure during exercise. Furthermore, a rise in post-exercise metabolism of 80 to 100 calories is considered a significant EPOC. It is critical to recognize the long-term advantages of small increases in total exercise energy expenditure caused by an increased EPOC. For example, the cumulative effect of EPOC over a year might be the equal of up to 10 pounds of fat in terms of energy expenditure.

How CAROL offers the best EPOC

According to research, the intensity of an exercise has the biggest influence on EPOC. Throughout a workout regimen, high-intensity interval training (HIIT) entailed alternating brief bouts (30 seconds to five minutes) of higher-intensity sessions with either rest or lower-intensity workloads. According to research:
  • HIIT is a time-efficient strategy for improving numerous health parameters
  • HIIT generates a sizeable and prolonged EPOC
We recently compared the EPOC after CAROL intensive and fat burn rides to typical workouts that followed public health physical activity recommendations: 20 minutes of vigorous-intensity treadmill exercise and 30 minutes of moderate-intensity treadmill exercise. The excellent findings revealed:
  • CAROL workouts are by far more time-efficient and induce a more potent EPOC
  • CAROL fat burn rides take 25% less time and induce a 20% greater overall energy expenditure
So, when you make the choice to take your first ride on CAROL, you are making a smart choice to dramatically improve your health and wellbeing.

CAROL is unique in three ways: REHIT, AI, and DESIGN.


REHIT (Reduced Exertion High Intensity Training) HIIT (High-Intensity Interval Training) is an improved version of HIIT (High-Intensity Interval Training) that is more effective than traditional exercise and requires considerably less time. This allows you to obtain maximum fitness in the shortest amount of time. The CAROL cycle is the only consumer-friendly exercise bike that provides REHIT exercises at home. A lab is the only other method to get proper REHIT training.


CAROL’s AI is programmed to optimize your workout so that you may achieve your greatest potential at all times. CAROL’s AI tracks your progress on each ride and tailors each one to your skill level. It will keep challenging you to attain your greatest potential as you become fitter. It’s like having a personal trainer and fitness coach on your bike at all times – and they’re always there when you need them.


The CAROL bike is a commercial-grade exercise cycle with built-in artificial intelligence that can direct and lead your rides. An on-screen guidance shows you when to pedal, and the brakes are automatically adjusted so that you get the optimal amount of resistance and intensity. REHIT exercises need hitting the exact appropriate degree of resistance at the exact perfect time — just when you’ve built up enough speed to tire your muscles. The CAROL bike can alter your resistance level automatically, accurately, and nearly immediately, which means it can apply the proper resistance for you, at precisely the appropriate time, in a fraction of a second.

How does CAROL get you in shape quickly?

CAROL’s AI software learns your baseline health, allowing you to benefit from personalised exercises with optimal workout intensity to help you accomplish your particular fitness objectives.

During your first six sessions (dubbed “calibration rides”), CAROL’s self-learning algorithms adjust the resistance level according on your weight, power output, and fatigue index in each session as you develop fitter and stronger.

Unlike any other indoor exercise bike on the market, CAROL gives riders the level of resistance they need to reach optimum intensity. Standard bikes can’t do this since the supra-maximal resistance needs to be tailored to the rider’s goals, demands, and physiology.
