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.

Client Reviews

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

A few years ago, I pinched a nerve in my neck which led me to be stationary as any form of movement would cause extreme pain. During this time, my fiancé (Sean) started at JKC and loved it!! Once I overcame the nerve issue, Sean spent a long time trying to convince me that JKC is exactly what I needed to safely start working out again (I’m slightly stubborn and was super scared of re-pinching the nerve). Long story short, Sean was right… as much as I hate to admit it!

I never had luck at gyms, if it started to hurt I would call it a day. At JKC that is not an option, as Jon & Thomas will push you to finish the workout, whether you want to or not! Working out in a group setting is also a big benefit of working out at JKC, if you’re not feeling motivated you can simply feed off of someone else’s energetic vibes.

JKC was recommended to me by a fellow runner. I was experiencing injuries, and feeling weak and fragile. When I started with JKC, Jon asked me about my goals and my focus. I wanted to concentrate specifically on running, and preventing injury. Jon developed a program for me that has enabled me to focus on my form and strength and has been flexible enough to enable me to train for many different races. I have been training with JKC for six years, and during that time I have enjoyed Jon and Thomas’s expertise in a very warm and supportive atmosphere.

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.

My initial goal was to find qualified personal training services in a personalized small gym setting. I have never been a fan of large gyms. JKC offers a friendly, happy gym experience that motivates me to strive for bigger and better results every week. Jon, Thomas and Craig are genuinely talented and always excited to celebrate everyone’s success.

I have a passion for challenging myself to achieve or beat goals. My favourite memories take me back to greater wins than I ever imagined with deadlifts and after a lot of determination and hard work, being able to do multiple chin-ups. Training at JKC has been one of the best experiences of my life – thank you for your commitment to helping me stay fit!!💪🏼😅
