Client Reviews

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

I started training at JKC in 2016 because I’ve always had upper back issues that became aggravated through work. I sought out other training and physio, but experienced little to no results. A client of mine happened to be coming to JKC for a similar issue and highly recommended it. I have had great success and haven’t looked back! I always feel like I’m getting programs tailored to my needs and I’m never bored. I’m 30 weeks pregnant now with my second child and have been able to workout through both pregnancies here at JKC. Even on my least mobile days, I felt safe to workout because my programs were specifically modified for my needs.

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’m 40 years old & started training at JKC in 2015. The gym I was working out at closed and my husband recommended JKC. JKC meets you where you are in your fitness journey and tailors the work to help achieve your goals. I’ve trained with Jon & Thomas pre pregnancy, while pregnant and now post baby and they have helped me enormously to stay fit through all life phases.

I joke with the guys often that I’ve seen no change in my fitness level since joining the gym, but the reality is I’m in far better shape at 40 than I ever was at 30 thanks to them.

Personal Strength Training by Thomas King

I started at JKC after a good friend recommended it to me. She had been coming for about a year and I was envious of her great results. I felt sluggish after failing to motivate myself with various home workout routines. I love the fun and relaxed atmosphere at JKC. It’s such a comfortable gym space and I enjoy knowing so many of the people I work out with. Jon and Thomas make an effort to introduce everyone to each other and with all the joking around,  it starts to feel like a family. Not to mention the awesome results. I’ve always liked to run on a treadmill but I’ve never had the drive to lift weights on my own. Going to JKC makes me accountable which was what I really needed. I feel so much stronger and healthier than I did 4 years ago when I started.

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.
