CAROL
The shortest, most effective cardio.
AI-powered workouts proven to give you the benefits of a 45-minute run in as little as 5 minutes.
Reach your fitness goals with the CAROL bike.
Get double the results
Studies have proven that doing three REHIT workouts a week will give you double the health and fitness gains vs. five 30-minute moderate intensity workouts per week.
Backed by science
CAROL’s revolutionary workout is based in the science of REHIT, Reduced Exertion High-intensity Interval Training.
This is HIIT, taken to the next level. Developed by scientists looking for the most effective, efficient workout possible.
It turns out that two 20-second, maximum intensity sprints are all you need for a great cardio workout. Those two sprints are like a switch — triggering a release of glycogen from your muscles that tells your body it needs to get fitter, now.
REHIT: next-level HIIT
By following the principles of REHIT, the maximum intensity levels during a CAROL sprint are about 2.4× higher than in HIIT spin classes. This means our workouts deliver bigger health and fitness benefits in 20% of the time compared to regular exercise.
CAROL’s REHIT workouts automatically apply the optimal resistance, at the right speed, at the right time – all based on your personal fitness level. It’s a level of precision that you won’t find from any other form of exercise, with unmatched benefits.
