Be super efficient with this 20-min bodyweight circuit you can do in the comfort of your living room.

By Jon-Erik Kawamoto, MSc, CSCS, CEP

This workout is surprisingly challenging for only being 20-minutes. I was sweating and panting by the end!

The St. John’s Board of Trade hired me to host a ZOOM workout this morning. It was very successful and I even was sweating and panting at the end!

I promised to share the workout on our blog, so here we go.

You might be wondering what a “Tabata” is? Tabata is common slang in the fitness industry these days to describe a workout method that involves 20-seconds work and 10-seconds rest. It’s actually the last name of a researcher from Japan. His full name was Izumi Tabata and he led a famous study that looked at cyclists performing supramaximal sprints on a stationary bike. I don’t need to get too deep into his research here, but I will send you to an article I wrote for Bodybuilding.com called The Real Tabata: A Brutal Circuit from the Protocol’s Inventor if you want to read more.

The full workout protocol is 20-sec hard, 10-sec easy for 8 rounds which equals 4 minutes.

In today’s Zoom workout, we did 20-minutes worth, so 5 rounds of 4 minutes. No rest was taken between sets.

I chose JKC originally to help prevent rowing injuries. I’m a rower and we won the St. John’s Regatta in 2019 but I rowed through a rib stress fracture and missed significant time in the boat during the racing season. Training at JKC consistently since the pandemic helped me stay injury free this year and made me the strongest I’ve ever felt, which helped me help my team win the 2021 St. John’s Regatta! Jon adds variety and mixes the exercises up well so that the workout goes by quickly and strength is gained. The gym is very personable and I like the eclectic mix of people that are there. JKC is much more intimate and personal than other gyms.

I recently visited Newfoundland for one month, and was looking for a good place to train while I was there. Jon and the team at JK conditioning really took the time to assess what I already knew, and set achievable goals for the time that I had with them. The gym was such a great place to push yourself. It had everything you needed, but more importantly it had a well organized, very knowledgeable, and really motivating group of trainers to push you at each workout. Not to mention a really nice group of other members who also motivated me to go that little bit further. I would highly recommend the gym to anyone who has a goal and wants to find a place to help them achieve it.

I heard really good things about it from my sister, and I could see the positive results she was getting.  I needed to do something.  I was overweight, depressed, and recovering from a back injury.  I had reached a point where simply getting up out of a chair was becoming difficult.  I knew that if I didn’t do something about it my senior years would be very burdensome to the people close to me.  I’m so glad I did!  After just a few weeks my day-to-day pain was drastically reduced, and my mobility increased. I had the confidence to try sea kayaking, and I now play ice hockey twice a week!

The key difference is the expertise.  The trainers know the gym equipment and the exercises, but they also have degrees in kinesiology, and can apply what they know to your workout.  As someone who was in poor physical condition starting out, I was worried about hurting myself.  Previously I tried an outdoor weekly bootcamp and injured my knee by pushing too hard.  The trainers at JKC constructed a program that started at the right level for me, evolving it as I grew stronger and more fit.  I feel well looked after.

I originally chose JKC to help me rehab following back surgery. JKC was the first gym where a trainer took the time to help me identify my goals and tailor my workouts to achieve them in a safe and doable manner. 🏋🏼 Jon & Thomas are both highly professional and knowledgeable. 👨🏼‍🎓 With their guidance and informative explanations 🗣 they have enabled me to reach my ever evolving goals. At JKC I’m guaranteed fun 😆, interesting 🙃 and diverse workouts, with Jon & Thomas forever supportive and encouraging. 👏🙌👍👊

I’ve always struggled with both my weight and anxiety throughout my life. As a writer you live a pretty sedentary lifestyle filled with both realistic and unrealistic deadlines, so I needed something to get me off my butt and to get me moving. JK has been a godsend during this past year and a half in particular. The pandemic has been tough, but workouts with both Thomas and Jon have really helped reduce the stress and strain of a global pandemic, and added an anchor of normalcy back into my life — which has been worth its weight in gold.

JKC has created an incredibly inclusive environment that’s filled with all kinds of supportive folks from all kinds of different backgrounds. For folks like myself, being surrounded by people with such athletic ability can be intimidating in most gyms. It can actually be a deterrent, and it sometimes has been for me. But, at JKC it’s far from that — it’s inspirational. Everyone supports one another. Which is something that’s not easily found in this day and age, inside of a gym or out. Not to sound like a total cheeseball here, but it really feels like a family.
