Get Fitter

CAROL Bike increases the maximum amount of oxygen you are able to use during exercise – your VO2max – by 12%.

Get Fitter

VO2max is the main measure of fitness. The higher your VO2max, the fitter and healthier you are.

A study by Western Colorado University split participants into 2 groups. Group 1 did 3x short Reduced Exertion HIIT (REHIT) workouts on a CAROL Bike each week; while Group 2 did 5x 30-minutes of moderate-intensity continuous training.

In just 8 weeks, the CAROL Bike group increased their VO2max by 12.3%, the other group by only 6.9%. That’s close to double the improvement—in 90% less time.
