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.

I chose JKC because I was looking for something different. I’ve seen and done the trendy workout programs before, I was looking for something that I knew I could see myself still doing a year from now! JKC has a lot of clients that have been going for years. That was a huge motivator for me! The small group coaching sessions are great and I really enjoy the format. It’s nice having 2-4 people working-out with you during your session. The camaraderie is great, everyone is very upbeat and positive – zero gym judgment!

I came to JKC through recommendations from my peers from lululemon. As a current ambassador, I’ve been introduced to legacy ambassadors, like Jon, and I knew a bunch of other people from the store were working out here so I wanted to give it a go. I often dread lower body workouts so I started coming here to do legs. I’ve had such great progress that I now come twice a week— and, I no longer hate leg day!

I’ve never experienced this sort of hybrid between group workouts and personalized service. Many group strength training services offer a sort of one-size-fits-all workout for the general population, which has never been of interest to me, because I want my workout tailored to my needs! I LOVE that you can be in a group setting while doing your own personal program; I love the camaraderie and community at JKC, and, I’ve seen incredible results thus far! Jon is always so attuned to what I need.

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’ve been weight training on and off for years but never really had a specific goal or target in mind so routinely stalled out, plateaued or stopped training all together. Before I joined JKC I was definitely in a fitness slump and needed something to motivate me and get me back on track. I did a bit of digging online, looking at various personal training options and gyms around town but JKC seemed like the best option by far. I’ve tried big box gyms and other personal trainers in the past but none of them have had the perfect combination of goal specific fitness programming, welcoming and supportive environment, and the knowledge and passion to back it all up that you’ll find at JKC. Jon and Thomas are great to work with, they know how to motivate you if you’re having an off day and are well versed in all the different ways to make your muscles burn! I also have noticed some major improvements in my deadlifts since I started with JKC and was really happy with the result.

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.
