In a busy world, efficiency is king. Everyone wants the most payoff for their efforts in the least amount of time—especially when it comes to fitness. That’s one of the reasons that high-intensity interval training, or HIIT, has become so popular. Workouts lasting just 20 or 30 minutes can deliver tremendous cardiovascular benefits, help you burn fat and lose weight, build stronger muscles and bones, lead to better blood sugar control and insulin sensitivity, and make you stronger. But what if you didn’t need to devote 30, 20, or even 10 minutes to your workout? What if you could achieve the same results, maybe even better results, in just 4 minutes? Enter Tabata.
Tabata is a specific type of very-high-intensity interval training. When done correctly, the entire workout takes just 4 minutes. The rub here is that doing it “correctly” means taking yourself to the limit in just 160 seconds of work. Tabata is tough. It’s also, according to research, incredibly effective.
If you’ve been hanging around the blog for a while, you probably know that I’m a big proponent of workouts that are short and sweet—or rather, short and intense. This former marathoner has seen the errors of his ways, and I’ve spent years trying to convince my readers that the typical fitness paradigm has people engaging in workouts that are too long and that exist in the so-called “black hole.” They’re too hard to be aerobic but not hard enough to yield max anaerobic benefits. In other words, workouts that break you down at least as much, if not more, than they build you up in the long run.
But Tabata isn’t your typical HIIT protocol. It’s not your typical sprint protocol (my preferred type of high-intensity exercise). It’s not your typical microworkout (despite being bite-sized). Tabata is its own beast altogether.
The questions at hand today are: Should you be incorporating Tabata into your workout routine? If yes, how? If no, why not?
The Tabata Workout Protocol
Tabata workouts are named after Dr. Izumi Tabata, researcher and former fitness coach for the Japanese National Speed Skating Team. Dr. Tabata was the first person to systematically measure and publish the results of the training protocol that now bears his name, although he, apparently, did not actually come up with the idea. (That was 1980s speed skating coach Kouichi Irisawa.) A true Tabata training protocol, according to Dr. Tabata himself, involves 7 to 8 “exhaustive sets” of exercise performed at 170 percent of VO2max for 20 seconds, with 10 seconds rest in between. If you quit after 6 reps, that’s not really Tabata. Nor is it Tabata if you can eke out a 9th round, if you do 30-second work intervals, or if you rest for more than 10 seconds.
Dr. Tabata conducted his studies using a stationary bike, which allows you to crank up the resistance and quickly get to that hard effort. Now I don’t know if you’ve ever pedaled a bike at 170 percent of VO2max (which equates to the intensity you are able to maintain for just 50 seconds of hard pedaling before you fall off the bike in a pool of sweat), but let me tell you, a 4-minute workout will feel like plenty. Even though you’re only going hard for 20 seconds at a time, the 10-second rest intervals aren’t enough for you to truly recover, so you start each new interval already in a deficit. After 8 rounds, you’ll be spent.
That’s what Tabata is. What is it not?
Tabata Versus HIIT
Tabata is not HIIT. Or HIIT is not Tabata? One of the two.
In any case, Tabata differs from HIIT in several key ways. HIIT workouts generally last 20 or 30 minutes, perhaps up to an hour. Tabata workouts last exactly 4. No more. With HIIT training, recovery periods last anywhere from 30 seconds to a few minutes, and they can involve either total rest or lower-intensity activity—pedaling at a lighter resistance, for example. Tabata workouts involve 10 seconds of total rest, period.
True Tabata, as described by the eponymous doctor, must be conducted at the prescribed intensity. HIIT workouts, though challenging when done correctly, aren’t nearly that intense. That last point is where a lot of people get confused. There’s simply no way to keep going for 20 minutes, much less an hour, at the intensity the Dr. Tabata prescribes. Even the world’s fittest elite athletes would struggle to complete multiple rounds with proper form and at the right intensity, much less your average bloke hitting an hour-long “Tabata class” at the local gym. To go for that long, you’ll be forced to decrease your output. These so-called Tabata workouts that stack together multiple rounds of 20-second on/10-second off exercises are not Tabata in the truest sense. Tabata-style, maybe. HIIT, definitely. Which is fine. There are plenty of demonstrated benefits to HIIT—but it’s not Tabata.
Tabata Versus Sprinting
Tabata and sprinting have a lot in common: Very brief, very intense work intervals. Relatively short. Leave you feeling more invigorated than wiped out for the rest of the day. But Tabata isn’t sprinting.
