Client Reviews

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

JKC was recommended to me by my good friend Casidhe Dyke. Cas had been training with JKC for a while, and both he and his father had seen great results from the personal training that Jon and Thomas were giving them. I was and still am primarily a triathlete and I’ve always struggled with injuries. I was talking to Cas about incorporating more strength training in my program to try and prevent injuries going forward and Cas suggested that I give JKC a try. I reached out to Jon not long after, and the rest is history! After working with Jon and Thomas for a few months, I was getting stronger, faster, and most importantly, I was staying injury-free. I ended up being able to train the whole season without significant injury and posted a personal best at Ironman Copenhagen in 2018. A big part of that was due to the strength training and coaching I received 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.

I’m 30 — started at JKC Aug 2016. I moved to NL to open lululemon and we chose Jon as one of our store’s ambassadors, did one workout and have raved about it ever since! The JKC team can adapt a workout no matter what the situation — injuries, new goals, you name it! The trust and expertise can’t be matched!

I joined JKC because I wanted to better care for my physical health, but didn’t really know how, or where, to begin.  Seeking help from a trainer seemed like a wise choice, and I had heard great things about the staff at JKC. Anyone who knows me knows that I hate exercising.  So, I’ve only ever tried sticking with a gym routine twice in my life.  Each experience consisted of me wandering around, not knowing what to do, and settling for an elliptical machine or something else that seemed comfortable and non-threatening.  Each session was the same, and I felt like I was wasting my time.

Each session at JKC, however, is specifically crafted for me.  I don’t have to think about what to do, because I’m told what to do.  I don’t have to worry about how to do things properly, because I’m shown (sometimes multiple times!) how to accomplish each task.  I don’t have to be concerned about slipping into a comfortable routine, because Jon and Thomas won’t let that happen.

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.
