The CAROL HIIT bike

What’s in this video?

My review of the CAR.O.L (Cardiovascular Optimization Logic) interactive HIIT bike that uses artificial intelligence to figure out how hard to push you in every ride; giving you a high-intensity workout with only 40 seconds of hard work (which the makers say is as good as a 45 minute jog) - and you don’t even sweat.

The company loaned me the bike to test out across eight weeks while I was at home during San Francisco’s shelter-in-place order that was triggered by the COVID-19 outbreak. [EDIT 2022: I ended up buying the bike at a discounted price].

This video also features CAROL’s CEO, Ratna Singh, on how the bike gets to know your ability, the science behind it, and why she believes humans are better suited to high-intensity interval exercise instead of lengthy cardio sessions.
