Our Manifesto

At JKC, we believe that talking about our goals is important to help us bring a clear vision into reality.

A manifesto, or a statement of intentions, reminds us to strive to be better everyday. Our manifesto is symbolized by the image of the dragon.

The dragon represents triumph over adversity, renewed fire within, and transformation through self-knowledge.

Not only do we build physical strength in the gym but the physical practice also builds strength of character. We can use this strength to help us create a vision for our lives and develop perseverance to achieve it.

As part of our community, we want to help you be better everyday. You’ll see the dragon image throughout our gym space as a reminder of why we’re all here.

Our Mission

Our mission is to help people become their strongest, fittest selves through expert coaching in a nonjudgmental, supportive gym environment.

Personal Strength Training by Thomas King

I started at JKC after a good friend recommended it to me. She had been coming for about a year and I was envious of her great results. I felt sluggish after failing to motivate myself with various home workout routines. I love the fun and relaxed atmosphere at JKC. It’s such a comfortable gym space and I enjoy knowing so many of the people I work out with. Jon and Thomas make an effort to introduce everyone to each other and with all the joking around,  it starts to feel like a family. Not to mention the awesome results. I’ve always liked to run on a treadmill but I’ve never had the drive to lift weights on my own. Going to JKC makes me accountable which was what I really needed. I feel so much stronger and healthier than I did 4 years ago when I started.

I had always wanted to start lifting weights and get stronger, but didn’t know where to start. I was looking not just for a gym, but for training on proper technique to prevent injury and a program designed for my specific goals. I also wanted a fun and supportive atmosphere to keep me coming back. JKC delivered on all of this and more.

Jon and Thomas have a wealth of knowledge that help their clients get the most out of their time in the gym. Programs are continuously modified to keep the workouts challenging. Even through everyone’s program is unique, you always have the coaches and other clients cheering you on and pushing you to achieve new bests.

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 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.

After my children were born, I was completely out of shape. I had been active before my first pregnancy in 2008. I saw a post on social media about a charity event that was hosted at the gym. It prompted me to check out the JKC website. I was immediately impressed by the professional content and decided to give it a try. The professionally crafted and uniquely tailored work outs, as well as the sense of accountability and commitment that they foster. I have not missed a workout since joining – contrary to other experiences I have had when purchasing gym memberships. The flexibility of booking and rescheduling workouts, made easy by an online app, also contributed to my success in meeting my fitness goals.

I enjoy every session, working out with Jon, Thomas and Craig, as well as the “JKC Community”. Anytime someone achieves a personal best, I enjoy the celebration and support everyone gives each other. For me, I fondly remember achieving personal bests on bench press, chin ups and the sled push, in particular.
