The good news is there’s an AI-powered exercise bikethat gives you almost all the cardio benefits of a 45-minute run in under nine minutes. The bad news is you can’t use your “I don’t have time to exercise” excuse anymore.

London-based CAROL stands for “Cardiovascular Optimization Logic” and the site touts it as an intelligent software system with pedals,which is cool. But the real difference between CAROL and other exercise bikes is that CAROL is specifically designed for high intensity interval training. That’s the same science behind your online HIIT class — it’s all about burning muscular glycogenreserves. But unlike your sweaty, hour-long HIIT class, CAROL tackles your workout in less time than it takes to procrastinate putting on your workout clothes.

The case studieson CAROL’s health benefits are impressive, as is CAROL’s latest package deal. Now through Feb. 28 with code CAROL2021, you can get a CAROL bike(normally $2,995), plus you’ll get a free chest belt (normally $59), free shipping, and a one-year CAROL digital subscription (normally $144). You’ll save a total of $700 and change.

Aside from saving money, CAROL can also save you loads of time. The flagship “Intense” workout is only eight minutes and 40 seconds long. It starts with an easy warm up, then you pedal like a beast for 20 seconds (the HIIT part), recover for three minutes, hit it for another 20-second sprint, and then cool down. That’s it. The intensity is so short and you recover so quickly, you likely won’t even break a sweat. Check out CAROL’s awesome tutorialsto watch a woman killing it on a CAROL bike in her strappy heels.

The tech behind the CAROL bike is also impressive. CAROL has nine more hardware components than other e-bikes and by your seventh ride or so, the bike’s computer will have compiled enough data on your performance to create a workoutthat's customized to be as productive as possible. And if you don’t feel like doing one of CAROL’s seven tailored protocols, you can just use your Peloton subscription on it. Peloton syncs with CAROL like a gem.

No matter which way you spin it, this deal is great for our current stay-at-home lifestyle. And it’s no sweat.
