"The reason you buy this insanely expensive exercise bike is to access Carol Bike's signature reduced-exertion high-intensity interval training (REHIT) workouts. This is a signature five-minute workout that consists of two 20-second sprints, bracketed by a warmup, rest, and cooldown period."
"Carol's AI-enabled algorithms are able to personalize the exact level of resistance you need for each interval. The company makes all sorts of hyperbolic claims about this workout—for example, saying that five minutes on the bike is equivalent to a 45-minute run."
"To my grave disappointment that I must report that after two weeks of riding the Carol, I ... love it. Although I have yet to see improvement on my metrics—Carol notes that it can take up to eight weeks—I already feel stronger."
