It sounds too good to be true that you can get these incredible results by working out for only 8 minutes and 40 seconds, but the science behind this claim has been proven in multiple peer-reviewed scientific studies.

Loved by biohackers like Dave Asprey and fitness pros, CAROL has a 10,000 rider base and is suitable for use by any age and fitness level. Some CAROL owners say that a REHIT workout (REHIT is a time-efficient alternative to HIIT) on CAROL is like "Peloton on steroids".

REHIT workouts are scientifically proven to give you double the health and fitness benefits in 20% of the time compared to traditional exercise. CAROL is ideal for home workouts and suitable for any age or fitness level, helping you get in shape fast.
