If you are new to the fitness industry or have been around the block a few times like I have, I’m sure you’ve heard the Japanese name “Tabata” being used just as often as the words “set”, “rep” or “interval.” This Japanese last name has become famous (almost legendary) and is commonly used as a verb in the fitness industry to describe a form of high intensity interval training (HIIT) – 20-seconds of work with 10-seconds rest performed for 8 rounds. This is a form of interval training with a work to rest ratio of 2:1 (the work interval is 2 x the length of the rest interval) and is quite short in duration (only 8 rounds worth for a total of 4-minutes…just 4-minutes!). Now, you can perform more rounds if you wish, but the authentic Tabata protocol only called for 6-8 rounds.

You see, WAY back in 1996 & 1997, Dr. Izumi Tabata and his research team published two academic articles in the Medicine & Science in Sports & Exercise titled Effects of moderate-intensity endurance and high-intensity intermittent training on anaerobic capacity and VO2max and Metabolic profile of high intensity intermittent exercises. Since Dr. Tabata was the lead author of these papers, the protocol is given his name (how cool would it have been if his last name was Kawamoto?!?). Anyways, trainers and trainees have taken this 20-10 HIIT protocol and have sub’d in their own exercises thinking they’re doing the Tabata protocol, where in fact, there is only one exercise that resembles the actual Tabata protocol: a mechanically braked cycle ergometer, which was the exercise chosen for these two studies. Let’s have a quick look at the studies just to get a better understanding of this now legendary protocol.

A Closer Look at the “Tabata” Studies

 
Subjects were young male students (physical education majors) volunteered for both of these studies – most were “physically active” and were members of varsity sports teams (table tennis, baseball, basketball, soccer and swimming).

All protocols were performed on a cycle ergometer (Monark bike) and were preceded with a 10-minute warmup at 50% VO2 max. Notice that common Tabata exercises such as Thrusters or running sprints were not used in the actual studies.

Without getting too deep in to the science, I’ll just bring up the important facts. During the 20-sec exercise period, the intensity (on the bike) was equal to 170% (yes, 170%) of the subject’s VO2 max. This is an all out effort where oxygen is not the only source of fuel. The body has to resort to other energy producing methods to sustain a crazy high intensity like this. Makes you think twice about alternating front planks for 20-sec and body weight squats for the other 20-sec – the intensity is just not high enough with these exercises.

Also, something else important to mention, is that these studies were not designed to assess fat loss. The high intensity intermittent exercise protocols used were utilized to examine the affects on aerobic and anaerobic metabolism, NOT fat loss. In the 1996 study, Tabata and his team found significant increases in subject’s maximum oxygen uptake and anaerobic capacity following 6-weeks of implementing the “Tabata” protocol. In their 1997 paper, they state that the 20-10 protocol, “appears to stress both the aerobic and anaerobic energy releasing systems maximally.” What does this mean for you? If you can suffer 170% of your VO2 max for 6-8 rounds of 20-10, you’ll crank up your ability to utilize oxygen and ability to work anaerobically. You’ll also get a huge boost in your EPOC (excess post-exercise oxygen consumption) meaning that your metabolism will be in overdrive for hours after your workout finishes. This could potentially lead to more calories burned and more fat lost.

So You Wanna Tabata?

 
What’s the take home message here? Well, if you want to “Tabata” something, the only way you’re going to get the authentic Tabata experience is by doing 6-8 rounds of 20-sec work (on a cycle ergometer) at 170% of your VO2 max at 90 rpm with 10-sec rest periods. According to Tabata’s results, this will positively impact your aerobic and anaerobic capacities and ramp up your EPOC for days (okay, maybe not days, but for quite a while after the workout).

“If you can suffer 170% of your VO2 max for 6-8 rounds of 20-10, you’ll crank up your ability to utilize oxygen and ability to work anaerobically. You’ll also get a huge boost in your EPOC (excess post-exercise oxygen consumption) meaning that your metabolism will be in overdrive for hours after your workout finishes.”

“Tabata-ing” lunges and pushups will not give you the authentic Tabata experience. All you’re doing is lunges for 20-sec alternating with pushups for 20-sec with 10-sec rest periods between exercises. Will you still increase your heart rate? Yes. Will you benefit from it? Probably. Will you burn calories? Yup. But just understand, it’s interval training, but the results will not even be close to what Tabata and his team found in his two studies.

The Next Best Thing

 
So, you wanna Tabata stuff? Here’s the next best thing if you don’t want to die on the cycle ergometer – you’ll just die doing something else 🙂

Choose multi-joint exercises that use as many muscle groups as possible. Great exercise choices include:

  • Barbell, Dumbbell or Kettlebell Thrusters
  • Treadmill Hill Sprints (death!!)
  • Hard-syle Russian Kettlebell Swings
  • Concept 2 Rowing
  • Burpees
  • Air Dyne Sprints (also death!!)
  • Versa Climber Sprints (if you’re lucky enough to have access to one)
  • Cross Country Skiing

Perform these exercises as fast as humanly possible. Seriously. Crank it (without hurting yourself) for the entire 20-sec. Do you best to recover in 10-sec (good luck) and hit it again. Repeat 6-8 times or until you collapse on the floor in a heap (which ever comes first).

Just remember, the goal is work at an intensity far greater than your VO2 max (so, no, low intensity exercises don’t count). This will also boost your EPOC and your calorie expenditure post workout (and hopefully shed some fat).

Perform 1-3x/week at the end or beginning of your workouts. Make sure to warmup thoroughly. You wouldn’t want to pull a hammy (or a lung).

I came to JKC through recommendations from my peers from lululemon. As a current ambassador, I’ve been introduced to legacy ambassadors, like Jon, and I knew a bunch of other people from the store were working out here so I wanted to give it a go. I often dread lower body workouts so I started coming here to do legs. I’ve had such great progress that I now come twice a week— and, I no longer hate leg day!

I’ve never experienced this sort of hybrid between group workouts and personalized service. Many group strength training services offer a sort of one-size-fits-all workout for the general population, which has never been of interest to me, because I want my workout tailored to my needs! I LOVE that you can be in a group setting while doing your own personal program; I love the camaraderie and community at JKC, and, I’ve seen incredible results thus far! Jon is always so attuned to what I need.

I have never previously seen the passion and level of care that Jon and Thomas bring to everyone who works out at JKC. Their knowledge, insight and skills are extraordinary, and they work with everyone individually to ensure the best possible results. The attention to detail and to every person’s specific requirements and goals, and the incredible, constant encouragement they provide, is, in my opinion, what truly distinguishes JKC from any other program in which I’ve participated. I am extremely pleased with the progress I’ve achieved thus far, and it’s largely attributable to Jon and Thomas and the approach they take to training and working with people.

I had signed up for other gyms in the past and never went or rarely went. Something always got in the way or I was just too tired and lacked motivation to go. This way I’ve made a commitment to Jon or Thomas and I try very hard to keep my sessions once I’ve booked in. JKC is different from other gyms that I’ve tried in the past because no one is there to be “seen”. We are all there to get a good workout in and go on with our lives. And it’s a small gym so you get to know everyone and it’s like a big family. When I joined JKC, I couldn’t do a chin up with an elastic band, but I’ve slowly worked up to 10 free hanging chin ups. That was big because I hate chin ups.

I’m 34 and started at JKC in 2015. My wife joined while I was working away in 2015 and started making amazing progress while also completing exercises I’d never perform on my own. I felt I was missing out so I signed up. JKC helps in establishing goals while also having clear direction of what to do, and how, in each session. They also measure your progress which is another means of motivation! At other gyms I wouldn’t have a clear plan and would just use whatever equipment was free, it was hard to see any results. Between setting some personal bests and making good friends its hard to identify a favorite memory.  One that does come to mind was when I hit my target goal/PB in both bench and squats in the same session, big day.

I heard somewhere that achieving your health goals is determined largely by what you do in the kitchen. I am grateful to have found Julia who brought direction and accountability to this most important piece for me. Having Julia in my corner has brought me confidence and certainty that I am on my way to achieving my goals. I highly recommend her if you are serious about making a change and feeling better about your health.
