CAROL Bike's Reduced Exertion HIIT (REHIT) improves your fitness, including VO2max. And boosting it by 12% change is like turning the clock back on your age by 10 years.

What is VO2max?


VO2max stands for ‘volume, oxygen and maximum’. It reflects the maximum amount of oxygen you can burn while working out. Your VO2max will increase as you get fitter.​


VO2max and longevity


Studies show that having a high VO2max leads you to live longer and improve your health. Reducing your risk of major health disorders like cancers, heart disease, diabetes and strokes. Boosting your VO2max also helps lower blood pressure.

CAROL Bike was designed to get you fittest, fastest. With CAROL’s signature REHIT workout, you can increase your VO2max by 12%—in just 8 weeks. And it works like this: 2x all-out 20-second sprints, a brief warm-up and recovery. From just 5 mins, 3 times a week. CAROL Bike’s REHIT gets you fit, saves you time—and helps you live younger.​
