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. 👏🙌👍👊

Nutritional Coaching by Julia Howard

For the past two months I have worked with the JKC team and have never felt better! In addition to a personal fitness plan, JKC’s holistic nutritionist, Julia, worked with me and around my busy schedule to educate me on healthier food options and meal planning. I maintain a daily food log which Julia reviews and provides feedback on and we also have weekly chats to discuss my nutritional goals and potential improvement areas. Julia also helped me to identify and work around dietary constraints which have caused digestion issues for years!

Julia and the rest of the JKC family have helped me get my confidence back! I love starting my days with a good sweat and a healthy breakfast. I understand what foods make me feel my best and my body is well on its way to becoming more lean, fit and happy! I would totally recommend Julia and the entire JKC team!

I had signed up for other gyms in the past and never went or rarely went. Something always got in the way or I was just too tired and lacked motivation to go. This way I’ve made a commitment to Jon or Thomas and I try very hard to keep my sessions once I’ve booked in. JKC is different from other gyms that I’ve tried in the past because no one is there to be “seen”. We are all there to get a good workout in and go on with our lives. And it’s a small gym so you get to know everyone and it’s like a big family. When I joined JKC, I couldn’t do a chin up with an elastic band, but I’ve slowly worked up to 10 free hanging chin ups. That was big because I hate chin ups.

I am 62 years young and I started training with Jon in 2013. I originally came to join JKC as a recommendation from other family members that were onboard with Jon. Their enthusiasm for the gym experience was quite evident.  I was not to be outdone, so I decided to join as well. JKC, in my mind, certainly stands out from the crowd. I feel it’s a combination of the skill and passion the coaches have for their job and their clients. Each client is treated with the upmost respect and given time to explore their fitness journey without any pressure. JKC is certainly not a cookie cutter gym.The coaches customize your fitness program to suit your needs and your fitness level. This certainly makes sense because no two clients are alike.  This is where JKC excels! Jon, Thomas, and Craig keep the atmosphere at the gym light, but productive. A great combination that obviously works and makes the clients want to come back. Lastly, the camaraderie at the gym is everything. Meeting likeminded people who make you feel you are not alone in your fitness journey is everything.

I was referred to JKC by my sister-in-law and had heard good things about it from many people in the running community. I also saw Jon’s picture on the wall at lululemon years ago! I really like the personalized training and the variety the guys provide. I started for strength training for running. I love cardio and do tons of it but wasn’t motivated to do much strength work on my own. Jon mixes up my strength work week to week so I don’t get bored but also lets me work in a hard circuit for the last 20 minutes of most sessions to get my cardio fix
