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.

How We Work

Most fitness professionals promise “6 pack abs in 6 weeks,” or a similar message. We don’t do before and afters because there is no “after.” There is only continuous improvement. Also, our group training creates a community. When you join JKC, you are joining something bigger than yourself.

Custom Workouts in a Group Environment

Pay As You Go

Enjoy a different fitness experience. Pay for training on your terms with no long-term membership fees. Out of town? No worries. Only pay when you workout.

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 started training at JKC in 2016 because I’ve always had upper back issues that became aggravated through work. I sought out other training and physio, but experienced little to no results. A client of mine happened to be coming to JKC for a similar issue and highly recommended it. I have had great success and haven’t looked back! I always feel like I’m getting programs tailored to my needs and I’m never bored. I’m 30 weeks pregnant now with my second child and have been able to workout through both pregnancies here at JKC. Even on my least mobile days, I felt safe to workout because my programs were specifically modified for my needs.

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. 👏🙌👍👊

JKC was recommended to me by a fellow runner. I was experiencing injuries, and feeling weak and fragile. When I started with JKC, Jon asked me about my goals and my focus. I wanted to concentrate specifically on running, and preventing injury. Jon developed a program for me that has enabled me to focus on my form and strength and has been flexible enough to enable me to train for many different races. I have been training with JKC for six years, and during that time I have enjoyed Jon and Thomas’s expertise in a very warm and supportive atmosphere.

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.
