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.

Personal Strength Training by Thomas King

I started at JKC after a good friend recommended it to me. She had been coming for about a year and I was envious of her great results. I felt sluggish after failing to motivate myself with various home workout routines. I love the fun and relaxed atmosphere at JKC. It’s such a comfortable gym space and I enjoy knowing so many of the people I work out with. Jon and Thomas make an effort to introduce everyone to each other and with all the joking around,  it starts to feel like a family. Not to mention the awesome results. I’ve always liked to run on a treadmill but I’ve never had the drive to lift weights on my own. Going to JKC makes me accountable which was what I really needed. I feel so much stronger and healthier than I did 4 years ago when I started.

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. 👏🙌👍👊

My original reason for joining JKC was to get some sage advice to help with my running. I had been looking for awhile, came across Jon, met for an assessment, and was quite happy with how that all went. Apart from the running specific strengthening and conditioning approaches, JKC is different from other gyms as I am a fan of the small group sessions where everyone has their own goals and individualized programs. As well, the run coaching is super. All the coaches go the extra mile to make sure you get the best out each training session. They are fantastic motivators! My favourite memory is deadlifting 330lbs. Making a lot of great friends and meeting some really cool people is pretty high up on that list, too.

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.
