It is 8:47 am, and I’ve simply gotten again house from daycare drop-off. Meaning I’ve 13 gloriously free minutes earlier than I am alleged to log in to work. What to do? I may go wild and Swiffer the flooring (god is aware of they want it). I may open up my laptop computer early like I usually do. Or I may hop on the CAROL Bike in my front room and get in my full cardio exercise for the day—with sufficient time afterward to brew a recent cup of espresso.
Sure, it is potential: This high-tech stationary bike provides super-short-but-intense, scientifically-validated exercises that allow you to knock out your cardio train wants earlier than you actually have a probability to get sweaty.

Quick “train snacks” have turn out to be a preferred technique to squeeze power coaching or mobility work into spare moments of our work-from-home days. However most cardio exercises nonetheless require a good chunk of time to get the complete endurance-building, heart-healthy advantages (suppose: at the very least 20 to half-hour). Even if you happen to go for a excessive depth interval coaching (HIIT) exercise—which train scientists say is much extra environment friendly than moderate-intensity cardio—between your warm-up, settle down, the intervals, and restoration time, you are still often taking a look at an excellent half hour or so.
That is why, over the past decade, researchers have pushed to see simply how low we will go. The reply? “Only a couple 10- to 20-second all-out sprints is enough,” says Lance Dalleck, PhD, a professor of train and sports activities science at Western Colorado College who researches the affect of train on our well being.
The trick, nevertheless, is that these sprints should be dialed as much as max depth to make them really efficient.
How does the CAROL Bike work?
CAROL stands for “Cardiovascular Optimization Logic,” which sounds very fancy, and, effectively, it kinda is.
Here is the Cliff Notes model of the science: Analysis has discovered that if you happen to go laborious sufficient for 20 seconds, you employ up enough muscle glycogen to set off a cascade of favorable metabolic adjustments as your physique works to revive that glycogen. “You activate these pathways that make extra mitochondria (which results in improved cardiorespiratory health),” says Dr. Dalleck
That is why CAROL’s signature exercise lasts simply eight minutes with two all-out 20-second sprints, plus very low-intensity warmup, restoration, and cooldown intervals.
This technique has been coined “REHIT,” or diminished exertion excessive depth coaching. At first, it was solely obtainable in labs with tools that helped you hit these all-out sprints on the best depth. However the CAROL Bike ($2595) brings this science proper inside of individuals’s properties.
Dr. Dalleck has been sponsored by the American Council on Train to run a number of research on the CAROL bike over the previous 4 years, wanting into its results on issues like cardiorespiratory health, blood glucose regulation, and blood strain.
“The explanation why the CAROL bike is efficient is that it is in a position to make use of, I name it a ‘low-grade type of synthetic intelligence’ the place it is capable of detect your energy output with every dash, and the way a lot you are fatiguing, and keep in mind that for the subsequent session,” explains Dr. Dalleck. “So it is personalizing that dash for you.” That means that each time you employ the bike, it measures how laborious you are biking all through these 20-second sprints, and the way your coronary heart charge reacts, then recalibrates the resistance for subsequent time in order that it by no means will get simpler—whilst you get fitter.
By doing simply three of those eight-minute exercises for eight weeks, analysis exhibits that you may improve your VO2 max (a benchmark for cardio health) by greater than 12 p.c, lower your blood strain by 5 p.c, and cut back your threat of creating kind 2 diabetes by 62 p.c.
Such excessive outcomes from such a small time dedication would possibly sound like science fiction, however Dr. Dalleck factors out that the design of the exercise is predicated on a pair many years’ price of train science. “You’ll count on to see most of these advantages,” he says.

What the CAROL Bike is wish to trip
The CAROL Bike’s touchscreen offers you entry to 18 exercises. Throughout the two months I’ve acquired with my loaner, I concentrate on the one which issues (or, at the very least the one with all of the scientific hype): The 8-minute session with two 20-second sprints. Becoming it within the advisable 3 times every week sounds easy-peasy. I am a health editor, in any case, and run marathons for enjoyable.
After a few rides ramping me up (beginning with 10-, then 15-second sprints to get the grasp of them), I am prepared for the true factor. I can select between a handful of various genres of background muzak, or hear to a woman telling me a narrative a few tiger attempting to eat me. After one go-around with the tiger, I persist with the muzak.
Every trip begins off two minutes of tremendous gradual pedaling. As somebody with a nasty behavior of pushing the tempo in any cardio exercise, it takes me a number of tries to get the grasp of simply how straightforward I have to take it to maintain my coronary heart charge in the precise zone. (A coronary heart charge monitor strapped to my chest offers me away any time I get overzealous.) The bike manages the resistance for me, and at this level there’s barely any. In the meantime, prompts on the display screen cue my best respiratory sample.
Then, the display screen goes pink, the resistance turns method up, and I am supposed to offer it every little thing I’ve acquired so I do not turn out to be that tiger’s lunch. Let me inform you: Though 20 seconds sounds brief, the depth of those sprints makes them significantly no joke.
Ultimately, although, they’re over, and I’ve three minutes of restoration again at that gradual, resistance-free tempo. It is adopted by only one extra 20-second push, then a three-minute cooldown to progressively deliver my blood strain, coronary heart charge, and respiratory again to regular, for optimum restoration.
So technically, it is an eight-minute-and-40-second–lengthy exercise, however who’s counting?
Effectively, I’m. Each single time. As brief because the exercise is, it does not really feel prefer it goes by shortly. I discover the gradual pedaling so gradual that it is frankly boring. I am simply ready round for the dash, and infrequently find yourself scrolling my telephone till it is go-time.
To be truthful, I am not somebody who loves indoor biking to start with, and I usually want a fairly pumped-up teacher or deafeningly loud Taylor Swift tunes to maintain me engaged. However earlier than I attempted CAROL, I figured eight minutes was too brief to get bored.
A couple of weeks in, one thing on the motorboard of my bike breaks, and I’ve to confess I am just a little disenchanted when customer support solutions my electronic mail inside an hour, then FaceTimes me proper after, and sends a alternative half and a tech out to put in it only a few days later. Cannot a lady get an excuse to skip her 8-minute exercises round right here?
Who CAROL could be finest for
In our dialog, I point out to Dr. Dalleck that I really feel like, as environment friendly because the machine is, I personally discover it takes the enjoyment out of exercising for me. He chuckles and explains that though that is confirmed to be probably the most environment friendly type of cardio, it isn’t meant to be the one magic bullet that you just use solely all 12 months lengthy (until, hey, that is what you get pleasure from).
“Individuals’s seasons and availability to work out ebbs and flows,” Dr. Dalleck factors out. “So, if I’ve a month the place it is like, wow, I am gonna be actually strapped for time, or if it is the winter and it is chilly and it is snowing, throughout these instances of the 12 months, CAROL may be actually interesting.”
Which is smart to me: This may be one device in a periodized strategy to coaching. Nobody’s telling you it has to take the place of heading out on a leisurely path run on a ravishing day.
And there are occasions when this machine is actually best. One of many research Dr. Dalleck performed concerned placing one CAROL Bike in a publicly accessible place at his college, and one other in a shared widespread room at a neighborhood hospital. “Our individuals had been college staff and hospital staff who had been actually busy,” he says. “And so the thought is, you understand, they wanted a tiny, environment friendly exercise.” The CAROL Bike was the proper method for them to get in train with out even having to vary into gymnasium garments, for the reason that exercise is designed to maintain you from getting sweaty. (And, provides Dr. Dalleck, many of the individuals even reported having fun with it!)
I undoubtedly perceive that “tiny, environment friendly” enchantment. As a working mother who’s at present marathon coaching, there are some days when squeezing in a 30- or 40-minute run simply is not gonna occur. Hopping on the bike to get related cardio advantages within the time it takes for my pasta to prepare dinner can maintain me on monitor with out feeling like a burden on my schedule. Positive, it will not be my favourite mode of motion, personally. However the period of time it might save in my day makes it an extremely highly effective device to have the ability to use.
