When, in 2016, I wrote about a London company’s high-intensity interval training (HIIT) exercise bike called High Octane Ride, the idea of telescoping exercise down to as little as eight minutes, three times a week, sounded like the ultimate free lunch – even though its principle already had scientific backing.
The bike has been relaunched as Car.o.l (Cardiovascular Optimisation Logic) in a slicker, smaller form, with sophisticated, AI-based programming in the cloud. This means it monitors your routines live and adjusts resistance instantly, based on your heart rate, which it reads from the hand grips and pedalling performance. It was tested by the High Altitude Exercise Physiology programme at Western Colorado University for the non-profit American Council on Exercise – and found to work as advertised.
I know it works from a less scientific test at home. Alternating between sessions on my non-HIIT Peloton and Car.o.l rides, Peloton routines that left me a sweaty mess are now easy.
