Experience the Future of Fitness With The New CAROL AI Exercise Bike

Looking for the ultimate condition device? Look no further than the CAROL AI Exercise Bike, now available on Peak Athletics! 

This is the perfect addition to any biohacking routine and an essential for those who have limited time to exercise.

Picture this. You’re in between meetings, or you’ve just tucked the kids in. You’ve got 10 minutes of ‘me time’, tops. Jump on your CAROL AI bike, hit a button, and bam! Your workout begins. 9 minutes later, you’re done. And those 9 minutes? They’re the equivalent of a 45-minute jog. A quick wipe down, and you’re back in the game. Just like that.

So, How Does the CAROL Bike Work?

Get Fitter In Less Time

Thanks to CAROL’s science-backed Reduced Exertion HIIT (REHIT) method, you get an ultra-short and effective workout based on two 10 to 20-second sprints within a 10-minute span. These sprints kick your nervous system into “fight-or-flight” mode, increasing energy demands by 10,000%. And those glycogen stores in your thighs? They’re wiped out, replicating a 30-45 minute jog’s effect in just 9 minutes.

Three 9-minute workouts a week with CAROL is all it takes to revolutionise your fitness regime and save you valuable time.

Burn More Calories In Less Time

But the good things don’t stop with the fitness improvement.

The CAROL bike makes your body a calorie-burning beast. The sprints trick your nervous system into staying active, leading to a prolonged “afterburn effect”.

This means you continue to burn extra calories post-workout, which may help with fat loss.

CAROL Bike With Artificial Intelligence

With CAROL, every workout is custom-fit.

The bike uses artificial intelligence to tailor workouts to your unique physiology and ability:

First, the bike gathers personal information during setup, including your age, weight, and height.

It then blends this data with five decades of evidence on the REHIT method and onboard sensor feedback.

And finally, CAROL’s AI assesses your performance, making continuous tweaks from thousands of resistance settings.

The result? A personalised workout that improves your health and fitness every time.

Plus, the CAROL bike dynamically adjusts the resistance level of the flywheel during the ride (based on your power input and data from previous rides).

Why is that important?

Well, the AI predicts when exactly to put the resistance on, how much resistance to put on, and for how long to put it on. It provides the most optimal and effective workout every time and makes the sprints as effective as possible. This level of precision simply isn’t possible with traditional exercise or spinning bikes.

Built to Last

The guys at CAROL engineered the bike with high-quality materials, and it’s built to last. The centrepiece is a robust, powder-coated steel frame. This well-made frame offers a sturdy, shake-free ride even when you sprint. The bike also comes with a heavy 14kg flywheel, which allows you to get the momentum when you’re going all in

There are also two features that make the CAROL bike stand out: a frictionless magnetic brake and belt drive system. The brake uses magnets to increase resistance, ensuring a smooth, frictionless ride. The poly-V belt with automatic belt tensioner makes the ride feel very smooth, even when resistance peaks. Plus, it keeps things whisper-quiet so you won’t disturb the neighbours during your workout!

Fully Customizable

When it comes to customisation, the CAROL bike fits all body types. You can change the seat position and handlebar height for a perfect ride. Need hydration during your workout? No problem, CAROL’s got you covered with two bottle holders.

It also includes dual-sided toe cages and SPD click pedals for your choice of regular trainers or cycling clips.

A Wide Range of Workout Modes

CAROL offers several workout modes in five distinct categories:

  • Reduced Exertion HIIT (REHIT): Ultra-short and effective workouts based on two 10 to 20-second sprints. The signature REHIT workouts result in a series of chemical reactions. The adaptive response to this stress makes your body fitter, faster.
  • Fat Burn: Workouts designed for fat burning and weight loss, with 30 to 60 eight-second sprints mixed with rest periods. Combined with a healthy diet, this mode can drastically enhance metabolic fitness and help shed those extra pounds.
  • Free Ride: For those who want full control over their ride intensity, the Free Ride mode is ideal. Perfect for training in your AI-customised power and heart rate zones or use your CAROL with third-party apps like Peloton and Zwift. classes. And for those extra long rides? Connect it to your YouTube or Netflix account.
  • Custom Ride: Workouts of varying lengths, based on cutting-edge scientific research to deliver maximum health benefits.
  • Fitness Test: Standardised tests to measure Functional Threshold Power (FTP) and Maximum Aerobic Power (MAP).

Seamless Third Party Integration

CAROL isn’t just a standalone bike; it plays well with popular apps like Peloton, Zwift, YouTube, and Netflix. You can adjust and track your metrics while following along with Peloton or Zwift classes, or even binge your favourite Netflix shows.

Most indoor bikes lock you into just one program, but CAROL loves variety. You’re free to switch between programs as you please.

Data Is King

Love geeking out on data? CAROL’s got you covered with a detailed workout history and graphs. And if you’re somebody who doesn’t like data, the CAROL bike also simplifies things for you.

Another amazing feature is the weekly CAROL Leaderboards. Track your progress and compare your performance with other CAROL users worldwide, adding a competitive and fun element to your workout. Are you ready to hit the top 10%?

CAROL Bike Benefits

Despite that short workout duration, the CAROL bike provides the same benefits as much longer workouts. One study found that riding CAROL three times per week (for 26 minutes of exercise) provided the following health benefits:

  • Improved cardiorespiratory fitness by 12% as measured by VO2max.
  • Increased HDL cholesterol by 6%.
  • Reduced triglycerides by 10%.
  • Reduced blood pressure by 5%.
  • Reduced blood sugar by 2%.

Perfect fit
Size: 9-9.5, Color: Blue/Grey
I think these shoes are excellent. I ordered a pair which arrived after 2 days. Contrary to some reviews I do not find these water shoes a tight fit at all. And I have bunions. Indeed I find them very comfortable. I have used them in water and as advertised they drain dry pretty quickly. In short I am delighted with the shoes. So much so that I ordered a second pair. Different colour of course. They just arrived and I am wearing them now. Same size and just as comfortable. Thank you.

One day of use, then it rubbed against my toes and caused cuts
Size: 9-9.5, Color: Black Denim Blue, Size: 9-9.5, Color: Black Denim Blue
I got these right before a trip to Costa Rica where we would be doing a lot of hiking, some tubing, and be in and out of water. They felt great when I first tried them on and I was optimistic. Our first day, we hiked a total of about 5 miles in the forest and along a river, with some swimming in pools throughout the hike. These weren't difficult trails, but a mix of gravel, rock, dirt, etc. The shoes felt fantastic and were comfortable all day. Later that evening, after they had mostly dried out, we did another mile or so to some other pools and I had no problem. During that hike I was so happy I was actually talking to my kids about what great things I was going to say in a review. The following day however, as soon as I put on the sandals, just walking to the hotel pool, the top of the shoe, just above my big toes, was bending and rubbing against my toes. It was very noticeable and I took them off and made sure there was no sand or anything else causing the irritation. I had no other choice that day and we ended up back on a similar trail, hiking a total of about 1.5 miles, with it rubbing against my toes the entire time. I tried both tightening and loosening the shoes and changing my stride to step more flat footed so they wouldn't bend at the back of my step, but that didn't help. Neither did getting them wet again, hoping to soften something up. By the time we were half way through that hike, there were visible raw spots on top of both my big toes. By the time we were done, they had become sores and very painful. The following day, we walked on the sidewalk to breakfast about three blocks away and it hurt bad enough that I found a store and bought a pair of flip-flops instead. I haven't worn the sandals since. I can't tell exactly what's going on inside the shoe, but I think the leathery part of the shoe is pushing down at the natural break in the toe area when I step, and the mesh is rubbing. Since I've worn them outside and been swimming in them, I can't return them, but they're basically useless after one good day.

Great headphones!
Color: Black
Great headphone! They work well and sound quality was pretty good. Definitely worth the money. I love that they’re not inserted into the ear. It allows me to hear things going on around me but not so much that I can’t hear my music. They’re pretty comfortable too! I have smaller ears and the earbuds that you put into your ear tend to hurt after some time. These typically don’t.

If you’re curious about open ear earphones give these a try
Color: Black, Color: Black
I don’t normally review but these are genuinely great quality, especially for the price! I was skeptical about open ear for sound quality/comfort to be honest and the first couple days I used them they were a but uncomfortable and my ears hurt after a while, but once you figure out how to fit them properly and get used to it they’re actually incredibly comfortable, so much that I often forget I have them on lol. The part that hooks on your ear is a soft bendy plastic, silicone-like so it’s pretty forgiving for different ear shapes. I love the dual connecting Bluetooth as well, super useful for switching between tasks on different devices. The sound quality is pretty on par with higher end options and it doesn’t really leak sound much either, even though it’s open ear which is great, also allows you to still hear your surroundings really well so good for commuting/out and about/office work. Great battery life and they charge quickly in the case, I work in video editing so use them pretty much all day and with the case they last several days before needing a recharge. I’ve had them for a couple months now I think and I’m really glad I went with this option. Absolutely the best option I’ve tried around this price point, anker products as a whole I’ve found are really great quality at a very reasonable price.

COMFORT KING 👑✨
Color: White
I struggle finding headsets that don't bother my ears OR cause headsets 🙈 others will just fall right out which gets super annoying... These on the other hand, are like air!! I genuinely cannot even tell I'm wearing them! The ear piece is adjustable for all (or most) ears! The sound quality is amazing while still being able to hear what's going on around me. They don't fall out, the adjustments help with that too! Even on the tightest setting, it's not uncomfortable, the silicone really feels like butter. My only semi-complaint is that the battery doesn't seem to last very long, but I've only used them out of the box 🙈 I'm gonna charge a full day and see how they do! Honestly not a major problem anyway because I only wear one for work, when one dies I just swap to the other. Connectivity is quick and easy! If you are picky about ear comfort, I promise you, these will not let you down!! ABSOLUTELY WORTH THE MONEY
