Client Reviews

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

I was looking for something to augment my 20+ year yoga practice with a focus on strength conditioning. I am friend’s with Jon’s sister in-law and over the years always heard great things about JKC, especially with respect to the top quality trainers they have and programs they run. After talking to Jon about my goals, and hearing his thoughts on a training plan, I knew that this was going to be an awesome experience … and it sure has been. JKC stands out from other gyms because of the attention to detail, the high quality of the staff and the facilities. Also, the amazing people that train there. And no one posing and taking selfies. I’m 41 years old and I started in Dec 2021.

I started at JKC in January of 2014 and I’m 67 years old. When I had my Initial Assessment, I knew – almost immediately – that Jon knew what he was doing and what he was talking about. I was overweight, out of shape, and in serious need of someone, like Jon, who could get me back on a fitness/conditioning routine that suited me, my age, my less than acceptable physical condition, my sometimes intermittent RA, and my need for a structured, consistent and yet flexible training and conditioning program that would work for me.

Fundamentally, if I made a choice at all with respect to JKC – it was to continue to come back each week. I have not been in a lot of gyms. To be honest, they used to intimidate me. What makes JKC different is their approach to each and every one of their clients. Jon and Thomas – and now Craig – tailor each training regime to the particular needs of each client. That ensures that the training regime will suit each client upon the start of training and changes as the client improves. It adjusts for any physical setbacks such as injuries and it adjusts for success. It is just that simple.

It is also the consistent encouragement that comes from Jon, Thomas and Craig. That voice that comes to you while you are in the middle of a particularly difficult set – rear-foot elevated split squats comes to mind immediately – that says “good job” or “keep it up” or “just a couple more reps.” To know, in that moment, that you are not alone and the trainer is paying attention to what you are doing. That is priceless for me.

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!

JKC is different from other gyms/fitness regimes I have tried in the past because of my level of comfort with the facility and other JKC clients and the amount of knowledge both Jon and Thomas demonstrate through personal attention to form, core development and overall strength is outstanding. JKC is by far the best training hands on attention that I’ve experienced period and I have experienced many over a lifetime of activity and playing various sports. The facility has everything you require plus, as you will learn there are many ways to use every piece of equipment and Jon and Thomas are very creative! There are many age groups and professions who attend this gym from elite athlete’s to the rest of us and the casual but focused atmosphere in the gym makes each visit interesting, friendly and challenging at all levels.

A few of my wonderful friends and colleagues recommended JKC. I was told by one colleague that “It’ll be the best thing you ever do for yourself” and she was right! To be honest, I didn’t have much experience in any gym setting. And NO prior weight training experience. It was always so overwhelming! But from the first day, nothing was intimidating about JKC. Each workout is set up just for me, and with my specific skills and goals in mind. There are no stupid questions, you learn as you go, and what I really love, I always feel included and important, regardless of my skills/experience.
