Ever heard of the AI-powered smart bike that gives you the benefits of a 45-minute run in under 9 minutes?
Here's the deal: we already know HIIT training is a great way to work out. The bike uses REHIT — Reduced Exertion High-intensity Interval Training — which is HIIT taken to the next level.
With REHIT training, you can get better health and fitness results compared to steady-state exercise, in 20% of the time, just 26 minutes a week — and you’re not putting your body under the kind of stress that you get with chronic cardio, which can actually be damaging to your health and stall your weight loss.
I have a CAROL bike in my office, and I now use it for my REHIT breaks. You just get on the bike, you start riding, and in less than 9 minutes you’ve checked your cardio off for the day. This thing is a game-changer — it was developed in collaboration with fitness researchers and is clinically proven to give you the shortest, most impactful cardio workout you can get.
You don’t need to spend long hours working out to be in the best shape of your life. You need to work smarter, not harder.
My guest on today's show, Ulrich Dempfle, is Chief Product Officer and co-founder of CAROL. Ulrich holds degrees in business administration and mechanical engineering, and leads all aspects of product development at CAROL, from data science to software and hardware. Previously, he was the director of PwC’s healthcare AI initiatives in the UK, and has a wide range of experience in healthcare, engineering and startups.
The idea for CAROL was conceived in 2012 while working on chronic disease management programs for people with diabetes. The team found it very challenging to get people to exercise, and the main excuses they heard were a lack of time, and frustration with slow results. The beauty of CAROL is how REHIT solves these problems, offering a scientifically proven workout in under nine minutes. After discovering REHIT, the team embarked on creating CAROL, the first and only consumer REHIT exercise bike available.
Ulrich practices what he preaches, and uses CAROL regularly. He says his cardiovascular fitness has improved by 50%, and he has lost about 10kg and can now easily manage his weight without counting calories. His blood pressure was slightly elevated but is now optimal, and he’s in better shape than ever.

0:52.4 | Well, it's, uh, it's no secret that I'm a diehard coffee lover. |
0:55.6 | The taste, the aroma, the mental buzz, the cultural experience. |
0:59.5 | But I also care about my health. And so, uh, me and my team, but Keon, we want to |
1:04.1 | omission the craft to coffee that we could feel really good about and look forward to drinking |
1:08.2 | every day. And we really nailed it. Not only the flavor, but also, uh, the ability to be able to |
1:14.6 | make a coffee that's free of yeast, mold, microtoxins, pesticides. The way we roast it minimizes the |
1:20.6 | formation of what's called a chrylamide, but maximizes the flavor. So it's, it's not over roasted or |
1:25.8 | burnt or anything like that, which can also be bad for you in the coffee department. It's certified |
1:30.4 | organic, which is near unheard of for coffees to be certified organic and yeast, mold, microtoxin, |
1:37.0 | and pesticide tested by an accredited organization. It's specialty grade. It's package and nitrogen |
1:42.2 | flush bags to deliver the absolute freshest coffee possible right to your doorsteps. If you're sick |
