How We Work

Most fitness professionals promise “6 pack abs in 6 weeks,” or a similar message. We don’t do before and afters because there is no “after.” There is only continuous improvement. Also, our group training creates a community. When you join JKC, you are joining something bigger than yourself.

Custom Workouts in a Group Environment

Get the best of both worlds: a custom plan tailored to your needs and current ability along with the support from the JKC fitness community.

We Offer Flexible Scheduling

No locked-in days or times here. Train when’s convenient for you so you don’t have to miss workouts.

Pay As You Go

Enjoy a different fitness experience. Pay for training on your terms with no long-term membership fees. Out of town? No worries. Only pay when you workout.

Personal Strength Training by Thomas King

I wanted to add strength training to my cardio, but have always felt gyms to be a bit intimidating, and was worried I would hurt myself without some supervision and help. JKC was highly recommended by several work colleagues. Thomas and Jon are both fantastic, making sure that everyone gets a highly personalized work out in a very supportive environment. The attention to detail and professionalism are second to none. The groups are very small, but very supportive and make the workouts even more fun. Since getting pregnant (36 weeks as I write this) I’m so happy that they continue to help me get stronger while always being safe.

Nutritional Coaching by Julia Howard

From my initial consult with Julia, she was professional and knowledgeable as both a Registered Holistic Nutritionist and athlete. She was interested in my nutrition and fitness goals and the development of a plan that would set me up for success.

Julia designed weekly meal plans that were complete with recipes and shopping lists. The food choices were nutritious, easy to prepare, and ensured that I felt well nourished and energized throughout my training and non-training days. Not only do I feel leaner and more fit, but I have more energy and I feel much more in tune with my body and food choices. Julia really helped me put everything in place so I can continue this process going forward- I cannot thank her enough!

I started training at JKC in 2016 because I had built up a number of muscle imbalances from old injuries and activities like rock climbing which had led to some really bad posture and mobility issues. On top of that some friends had convinced me to sign up for a half-ironman. Working with Jon and Thomas was a way to pull my body back into alignment and make sure it wouldn’t fall apart during my race. The staff at JKC pride themselves on continuously advancing their knowledge, which leads to new and inventive way to address problems, old and new. I got my Dad to start training here and recommended JKC to all looking to improve their strength and fitness.

I’ve always been a gym rat, but was getting tired of the same ol’ routine. My better half was attending JKC and encouraged me to try it out. My favourite part of JKC is that is isn’t a gym – it’s a community. Jon and Thomas are awesome, and I love that every time I go I know who’s working out with me and we can socialize while working on our health. Everyone is supportive, encouraging and genuinely looks out for one another. It’s an upbeat and positive experience and I can honestly say that I look forward to each and every workout.

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!
