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.

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 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’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 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.

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.
