In today's fast-paced world, finding time to exercise can be a challenge. In fact, lack of time is the number 1 reason why most of us don’t exercise enough. But what if there was a way to achieve remarkable health and fitness benefits in a fraction of the time?
What is REHIT?
Reduced Exertion HIIT (REHIT) was developed by scientists in search of the shortest, most effective method to exercise. REHIT creates the most potent training stimulus with just 2 x 20-second sprints, triggering numerous physiological responses in the body. This method has been scientifically proven to deliver double the health and fitness benefits of regular exercise—in 90% less time.
With just 2×20-second sprints, 3x a week, REHIT is scientifically proven to be the most effective cardio workout—a moment of effort you can always master.
The Science Behind REHIT
Muscle glycogen plays a crucial role in REHIT workouts. During the intense sprints of REHIT, your muscles are forced to mobilize about 25-30% of muscular glycogen. This depletion of glycogen releases key signaling molecules, such as AMPK and PGC-1a, that prompt your body to become fitter and stronger.
As a result, you develop more mitochondria, increase blood plasma volume, and strengthen your heart, leading to improved aerobic capacity.
But Wait…How Does Muscle Glycogen Do This?
Muscular glycogen is a stored form of sugar found in skeletal muscle. It’s your body’s emergency energy reserve that you can utilize rapidly. Muscle cells need adenosine triphosphate (ATP) as its energy source.
ATP is essential for repeated muscle contraction, but there's not a lot of it. When your ATP runs out after only 2-3 seconds during maximum-intensity exercise, your body can convert phosphocreatine (found in skeletal muscle) to ATP for another 8-10 seconds. It is then forced to use muscular glycogen to create ATP.
The Benefits of REHIT:
Live healthier
REHIT offers a range of remarkable health benefits that make it a compelling choice for those seeking to improve their well-being. Research has demonstrated that engaging in REHIT workouts for as little as 15 minutes per week can:
- Significantly reduce the risk of type 2 diabetes by a staggering 62%
- Can lower blood pressure levels can also be lowered by 5%
- Improve triglycerides
- Positively impact blood sugar response
Live younger
Another fascinating aspect of REHIT lies in its ability to turn back the clock on aging.
The amount of oxygen you can absorb and use during exercise is referred to as VO2max, and this key fitness measurement hits a steep decline with age.
However, with REHIT, you can reset your VO2max to where it was a decade ago. Improving your VO2max by 12% in just 8 weeks can have a profound impact on your overall well-being.
It's like rejuvenating your body and regaining the vitality of youth. Studies have shown that a 10% increase in cardiorespiratory fitness can significantly reduce the risk of mortality and morbidity, making REHIT a powerful tool for longevity.
Western Colorado University Study
This study compared 2 groups: one performing 3x short REHIT workouts per week, and the other engaging in 5x 30-minute sessions of moderate-intensity continuous training.
Surprisingly, the REHIT group experienced a remarkable 12.3% increase in VO2max, nearly double the improvement observed in the other group, despite investing only 10% of the time. This underscores the efficiency and effectiveness of REHIT in maximizing fitness gains.
Maximize calorie burn
One of the notable advantages of REHIT is the significant afterburn effect, scientifically known as Excess Post-exercise Oxygen Consumption (EPOC). The short, maximum intensity sprints generate a higher level of EPOC compared to traditional exercise.
This increased metabolic rate can last for up to 3 hours, leading to a higher overall calorie burn.
CAROL Bike: Bringing REHIT to the Real World
“CAROL is the only bike that accurately replicates REHIT outside of the labs. This scientific exercise cannot be done on a regular bike because it requires the supra-maximal resistance tailored to each person’s physiology.”
Dr. Niels Vollaard PhD, Exercise Physiology Researcher, University of Stirling.
Initially, REHIT was only possible in a lab setting. However, CAROL Bike, developed in collaboration with leading exercise researchers, has made REHIT accessible to everyone.
CAROL Bike is the only bike fully optimized for REHIT— making it simple, effective, and safe. With its AI-personalization and Instant Resistance features, CAROL Bike allows you to push your limits during the sprints, ensuring maximum intensity tailored to your individual physiology. This level of customization is essential for achieving the desired health and fitness benefits of REHIT.
CAROL Bike’s signature REHIT ride
CAROL Bike's signature REHIT workout consists of just 2×20-second sprints, making it the most time-efficient exercise routine available.
These short bursts of intense effort trigger the physiological responses needed to improve aerobic and anaerobic capacity. The warm-up and recovery durations are flexible, allowing you to personalize your workout.
The Efficiency of CAROL Bike Workouts
CAROL Bike's workouts are not only time-efficient but also highly effective. In just 5 minutes, you can achieve the same health and fitness benefits that would typically require a 45-minute run. The AI-personalized workouts are tailored to each individual's fitness level, making them suitable for anyone, regardless of age or physical condition.
New research by Western University Colorado demonstrated that more calories would be expended on a 15-minute CAROL Bike ride, than a 30-minute run. This is because the short, maximum intensity sprints on CAROL Bike generate a significantly higher level of afterburn compared to conventional exercise.

REHIT presents a groundbreaking opportunity for individuals who seek an efficient and science-backed approach to exercise. With its ability to deliver double the health and fitness benefits in significantly less time, REHIT has the potential to revolutionize the way we approach our fitness goals. Reclaim your health and fitness, transform your body, and turn the clock back on aging with REHIT and CAROL Bike—making every moment mean more.
