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.

Client Reviews

Read what clients have to say about their experience 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.

I’m 36 Years Old and started with JKC in 2013. In the past I’d often have motivated spurts of a gym routine but they would usually only last a month or so. It’s pretty easy to press the snooze button at 530 am when there’s no one waiting for you. The fact that the guys are always on time/prepared and motivated for your session adds a level of accountability to your shoulders to “get out of bed” and bring your best effort each time. From the pressure free trainers to the camaraderie that you create over time with the individuals you’re working out with, JKC is able to offer an experience many other gyms cannot.

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’m 30 — started at JKC Aug 2016. I moved to NL to open lululemon and we chose Jon as one of our store’s ambassadors, did one workout and have raved about it ever since! The JKC team can adapt a workout no matter what the situation — injuries, new goals, you name it! The trust and expertise can’t be matched!

I had been struggling with work-life balance resulting in not exercising or playing hockey as much as I had been doing in the past. In addition to being out of shape, I was starting to experience some back/shoulder issues and realized I needed to make some changes. Around this time, a friend (who was also a client) recommended JKC and that’s when I started!

You really feel part of a community where everyone is welcoming and supportive. You get a program that is designed specifically to achieve your goals, with the ongoing coaching, progress tracking and support required to achieve them. The JKC team are very knowledgeable about fitness and conditioning, and very engaging with everyone to answer questions or discuss anything and everything training related. I also like the flexible scheduling and gym times that work for my schedule (I like early mornings and evenings).
