Carol AI Bike

What is the Carol AI Bike?

The CAROL (CARdiovascular Optimization Logic) bike is  an Artificial Intelligence-powered smart stationary bike that promises to deliver the benefits of a 45-minute run in less than a minute. Its primary workout protocol consists of three weekly rides, each of which lasts less than nine minutes and requires just 40 seconds of hard effort.

How Does the Carol AI Bike Work?

Developed by scientists, the CAROL bike uses a relatively new exercise method called reduced exertion high intensity training (REHIT).

You may already be familiar with high intensity interval training (HIIT) — a popular workout method that involves short but intense bursts of exercise, followed by a recovery period.

REHIT is similar to HIIT, just with fewer and shorter intervals.

The goal of REHIT is to quickly deplete muscle glycogen stores — the body’s preferred fuel source — as rapid depletions of muscle glycogen have been linked to several benefits, such as improved aerobic fitness and insulin sensitivity (1 Trusted Source).

Carol AI Bike FAQs

I have a medical condition. Can I use CAROL Bike?

A.

A safe user experience is of the utmost importance to us.
All users must, prior to carrying out any exercise on CAROL Bike, complete this short Physical Activity Readiness Questionnaire (PARQ, see below) to ensure that the bike is used within the prescribed safety margins:
  • Has your doctor ever said that you have a heart condition and that you should only do physical activity recommended by a doctor?
  • Do you feel pain in your chest when you do physical activity?
  • In the past month, have you had chest pain when you were not doing physical activity?
  • Do you lose your balance because of dizziness, or do you ever lose consciousness?
  • Do you have a bone or joint problem (for example, back, knee or hip) that could be made worse by a change in your physical activity?
  • Is your doctor currently prescribing drugs (for example, water pills) for your blood pressure or heart condition?
  • Do you know of any other reason why you should not do physical activity?
Each CAROL Bike rider is responsible for their own health.
If a rider answers Yes to any of the questions, we request that the rider seek medical advice from a professional prior to using CAROL.
If a rider feels unwell when using CAROL, they must immediately cease use of CAROL and seek medical advice from a professional.
