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

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 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. 👏🙌👍👊

My initial goal was to find qualified personal training services in a personalized small gym setting. I have never been a fan of large gyms. JKC offers a friendly, happy gym experience that motivates me to strive for bigger and better results every week. Jon, Thomas and Craig are genuinely talented and always excited to celebrate everyone’s success.

I have a passion for challenging myself to achieve or beat goals. My favourite memories take me back to greater wins than I ever imagined with deadlifts and after a lot of determination and hard work, being able to do multiple chin-ups. Training at JKC has been one of the best experiences of my life – thank you for your commitment to helping me stay fit!!💪🏼😅

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.

I originally joined JKC because I was anxious about passing out and embarrassing myself since I hadn’t weight trained in a while and I’d hoped to find somewhere sympathetic. My husband @terry_hussey had been training at JKC and his success there made me miss the achievement you feel from a good workout. I went to meet Jon and immediately knew it was going to be a safe space for me. I was never judged for the fears I had and where I was starting from. Jon and Thomas made sure to check on me often, and found a way to challenge me but make me feel secure at the same time, and Terry and I were able to book sessions together, so working out became a shared win for us!

JKC is different from other gyms because of the personal growth you have outside JKC (the sessions inside JKC creates a great positive feedback loop!). You gain self confidence, learn how to show up for yourself, meet a community of newfound friends, and get the support of your trainers who are behind you 100%. I’ve left a scattered workout so proud of myself I’ve honestly shed a tear in the car on the drive home. JKC is the mental health relief valve I need to stay positive, and keep my anxiety and health related fears at bay.
