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 am the oldest client at JKC at 79 years, soon to be 80. I started training at JKC July 2021. I started at JKC because two of my three sons Justin and Michael and their partners Andrea and Keir and one of my doctors recommended JKC. They all train at JKC Now my wife Linda trains at JKC too. My third son Jonathan lives in Kingston. There is a congenial community atmosphere at JKC. People are introduced to each other. There is effective personal training at JKC.

I’m 35 and I started at JKC in November of 2019. I was coming off the win of the Royal St. John’s Regatta in 2019, and our crew was chomping at the bit to be stronger and faster for 2020. The reputation of JKC leached into our group and away we went! Unfortunately the regatta was cancelled due to COVID-19, but I just loved JKC so much I stuck around. JKC is different from other gyms because the level of experience the team has is unparalleled. Jon, Thomas and Craig all mesh well together and mentor me in a way that I know they love what they do and are genuinely excited to guide me towards my goals (and beyond). I really enjoy the atmosphere, the sense of community and all the positive vibes that I experience in every session. There’s never a time I don’t want to go because I’m motivated by the team’s coaching style and I get results.

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.

A few of my wonderful friends and colleagues recommended JKC. I was told by one colleague that “It’ll be the best thing you ever do for yourself” and she was right! To be honest, I didn’t have much experience in any gym setting. And NO prior weight training experience. It was always so overwhelming! But from the first day, nothing was intimidating about JKC. Each workout is set up just for me, and with my specific skills and goals in mind. There are no stupid questions, you learn as you go, and what I really love, I always feel included and important, regardless of my skills/experience.

I originally joined JKC because I was anxious about passing out and embarrassing myself since I hadn’t weight trained in a while and I’d hoped to find somewhere sympathetic. My husband @terry_hussey had been training at JKC and his success there made me miss the achievement you feel from a good workout. I went to meet Jon and immediately knew it was going to be a safe space for me. I was never judged for the fears I had and where I was starting from. Jon and Thomas made sure to check on me often, and found a way to challenge me but make me feel secure at the same time, and Terry and I were able to book sessions together, so working out became a shared win for us!

JKC is different from other gyms because of the personal growth you have outside JKC (the sessions inside JKC creates a great positive feedback loop!). You gain self confidence, learn how to show up for yourself, meet a community of newfound friends, and get the support of your trainers who are behind you 100%. I’ve left a scattered workout so proud of myself I’ve honestly shed a tear in the car on the drive home. JKC is the mental health relief valve I need to stay positive, and keep my anxiety and health related fears at bay.
