Get super fit in only 8 minutes

CAROL is like a friend. She looks nice and even talks to me. She motivates me over and over again. She makes sure, in a very personal way, that I am continuously getting fitter. You now probably think «who the hell is CAROL?!»


CAROL is a stationary bike for high-intensity interval training (HIIT), using artificial intelligence. With her AI technology she analyses your performance during every session. Its adaptive resistance makes you go to the limit and continuously improve your results. In your personalised account you can track your progress, so you can see how fit you are getting in real time.


What makes CAROL unique is that every workout is only 8 minutes long. But only 40 seconds of these 8 minutes are really exhausting. And by that I mean really exhausting! CAROL calls these intervals the sprints. In these sprints you go to your absolute limit. Nevertheless, CAROL promises that there is no need to shower afterwards, since you will not even sweat … and she is right!


Besides, the bike has a very sophisticated screen, including a breath pacer, display of your heart rate, RPM, time and sprints left, power watts achieved, and your octane score (which reflects your cardiovascular fitness). So, you get tons of information on each and every ride.


If you are stressed out and always looking for excuses to postpone your fitness, CAROL is just the right tool. Only 40 seconds of real challenge. You can do that, right? This makes it a real gamechanger. The bike delivers the same cardio benefit of a 45-minute run in an intense 8-minute ride. If you are the ultimate athlete, you can also select from other programs (e.g. the 20 minute fat burn with 60 sprints). For me, however, this fits more in the category of torture.


My experience with CAROL is that I go on the bike more frequently and I feel totally energized and a little proud afterwards.


The only downside is the price. But - hey - since fitness studios are closed anyway, now might be the right time to invest!
