The Carol bike looks very much like any other exercise bike you might find in a gym; it offers a lot of adjustability of position, a tablet for on-screen instructions and a rear wheel where the resistance is applied. While the bike itself is carefully engineered, the biggest difference is in the types of session the equiptment is designed to offer through its AI workout programmer.
The Carol bike’s purpose is to reduce the amount of exercise time required for health benefits, claiming that you can get "the health benefits of a 45-minute run in just 8 minutes and 40 seconds through a workout called reduced exertion high-intensity interval training (REHIT)". This almost too-good-to-be-true claim is backed by peer-reviewed scientific research.
