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

Get the best of both worlds: a custom plan tailored to your needs and current ability along with the support from the JKC fitness community.

We Offer Flexible Scheduling

No locked-in days or times here. Train when’s convenient for you so you don’t have to miss workouts.

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’m 43 and started at JKC just over a year ago. I started at JKC because of multiple recommendations from existing clients. There are 2 main elements that distinguish JKC for me. Firstly the sense of community. I’ve been to multiple gyms in multiple cities/countries, you just  can not manufacture the sense of community and support you get from other gym goers and the team. It’s very motivating and happy to say I’ve made some friends at JKC.

The other major distinguishing factor for JKC is the expertise and passion of the team. Jon, Thomas and Craig craft highly personalized programs based on my fitness goals and know how to push me best without being pushy. They pay close attention to ensuring my form is solid before encouraging me to take on more weight for the exercise. Plain and simple they love what they do and it shows.

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 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 chose JKC because I row/coach teams in the St. John’s Regatta and was looking to add strength training to our program. My wife is also running friends with Julia, so I got to meet Jon a few times and heard lots of good things. I like JKC over other gyms because of the level coaching I receive and the gym atmosphere. The energy in the gym helps me through the tough workouts.

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.
