I had always wanted to start lifting weights and get stronger, but didn’t know where to start. I was looking not just for a gym, but for training on proper technique to prevent injury and a program designed for my specific goals. I also wanted a fun and supportive atmosphere to keep me coming back. JKC delivered on all of this and more.

Jon and Thomas have a wealth of knowledge that help their clients get the most out of their time in the gym. Programs are continuously modified to keep the workouts challenging. Even through everyone’s program is unique, you always have the coaches and other clients cheering you on and pushing you to achieve new bests.

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.

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 turning 67 next month and I started my journey with JKC in 2018. Seven years ago I experienced significant foot pain which had a negative impact on my day to day activities. I learned that issues in other parts of the body need to be addressed to achieve a positive result. My doctor (Dr. Jessica Wade) suggested, along with some other therapies, that I could  benefit from the conditioning JKC had to offer. I previously had not trained in any gym. I observed how many gyms operated and had a sense that JKC would be more my style: training in a small group setting, having such personal attention, and a program meeting my specific needs is fantastic! I love the atmosphere at the gym. Everyone is accepted and you feel supported and comfortable.

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.
