CAROL is the innovative exercise bike that uses AI and REHIT (Reduced Exertion High Interval Training) to create personalised workouts that deliver maximum fitness and health benefits in the minimum time. Working out on a CAROL bike has been scientifically proven to improve cardio-respiratory fitness, reduce the risk of type 2 diabetes, help with weight loss, and improves other significant health benefits. This is smart tech for smart people who want to optimise their health and spend more time doing the things they love with the people they love, especially in the summer months. 

A massive 80% of the population doesn’t exercise enough, and lack of time is one of the main barriers. A ride on a CAROL bike combines REHIT and AI technology to deliver tailor-made workouts and is perfect for time-poor people who know they need to exercise to stay healthy but struggle to get around to doing it.  

REHIT is a time-efficient alternative to traditional HIIT and only takes 8 minutes and 40 seconds. It includes two, brief but hard, 20-second sprints that push the body momentarily to its limits. REHIT was developed by sports scientists Niels Vollard, PhD, and Richard Metcalfe, PhD, who designed what they believe is the optimal workout. It has been scientifically proven to give double the health and fitness benefits in 20% of the time compared to traditional exercise. 

The inventors of CAROL took REHIT out of university labs and combined science, engineering, and AI to create an easy-to-use exercise bike that gives quantifiable results with personalised workouts. This means that users of any age can get fit in the shortest amount of time, effectively, efficiently, and safely.

REHIT works when the two brief, maximum intensity sprints create a sudden spike in energy demand, like in a ‘fight or flight’ emergency. Pushing the body for this short moment to its limits is enough to force muscles to burn and deplete muscular glycogen, its emergency energy reserve, which sets off a chain of molecular triggers causing the whole body to get fitter and stronger. It is not possible to do REHIT on any other exercise bike.

Once CAROL’s AI algorithms have gotten to know you, through a series of ramp-up rides, they will calculate and change the resistance level of your personalised workouts to deliver maximum results, pushing you further than you could ever push yourself.

After only three short sessions a week for eight weeks, CAROL has been proven to:

  • improve cardiorespiratory fitness (VO2max) by 12%, adding two years of life expectancy
  • reduce the risk of type 2 diabetes by 60% 
  • reduce blood pressure by 5%
  • reduce triglycerides by 10%
  • increase good cholesterol by 6%

Ulrich Dempfle of CAROL says: ‘We invented CAROL to help people with type 2 diabetes and those who struggle with exercise. Now we’ve got thousands of users from biohackers to people in their late 70s, the ultra-fit to busy parents, and others who don’t have the time or desire to spend hours in the gym or jog. Regular workouts on CAROL make your body very efficient at processing sugar and fat, your heart and muscles get stronger, and your metabolism increases. The short duration of CAROL’s workouts puts less strain on the body than other forms of exercise, while providing numerous health benefits.’
