Client Reviews

Read what clients have to say about their experience at JKC.

I’ve always struggled with both my weight and anxiety throughout my life. As a writer you live a pretty sedentary lifestyle filled with both realistic and unrealistic deadlines, so I needed something to get me off my butt and to get me moving. JK has been a godsend during this past year and a half in particular. The pandemic has been tough, but workouts with both Thomas and Jon have really helped reduce the stress and strain of a global pandemic, and added an anchor of normalcy back into my life — which has been worth its weight in gold.

JKC has created an incredibly inclusive environment that’s filled with all kinds of supportive folks from all kinds of different backgrounds. For folks like myself, being surrounded by people with such athletic ability can be intimidating in most gyms. It can actually be a deterrent, and it sometimes has been for me. But, at JKC it’s far from that — it’s inspirational. Everyone supports one another. Which is something that’s not easily found in this day and age, inside of a gym or out. Not to sound like a total cheeseball here, but it really feels like a family.

I started strength training at JKC in the Spring of 2021. I am in my 60’s but happy to say I feel much younger since joining this gym. I joined JKC upon the advice of a doctor. I went through some difficult medical issues last year, that’s when one of my doctors recommended strength training at JKC. I have been physically active most of my adult life but mainly running and completed many road races as I am a distance runner. Strength training has definitely benefited me by increasing my stamina and energy. It sure has enhanced my recovery over the past year. I have the added benefit of becoming a stronger runner as well.

I had spent a fair bit of time in gyms in my teens and twenties but I turned away from the gym to focus on activities that I enjoyed more. What keeps me at JKC is that I do really enjoy it. I always feel that I’ve accomplished something when I leave at the end of my workout. The environment is really positive and focused on challenging yourself whatever your level of comfort and fitness. I’ve also seen results that I’m really happy with; having someone who really knows what they’re talking about to guide your workouts makes them way more effective and focused than just “going to the gym”.

Shortly after I started at JKC, I sustained a fairly major injury that took me off my feet for several months. When I started to get back to activity, it was very difficult. Jon and Thomas worked hard to tailor my workouts to my goals and what I could do. With their help, I’ve been steadily building back strength and function.

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. 👏🙌👍👊

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.
