Client Reviews

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

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.

JKC was recommended by a previous trainer who followed Jon online. He thought Jon’s approach to training was excellent. JKC employs well educated trainers who are very particular about technique and form. I have never injured myself because the trainers know what they are doing. They can always answer any questions I ask about my training. As well the trainers are friendly contributing to a relaxed and friendly atmosphere at the gym.

JKC is different from other gyms/fitness regimes I have tried in the past because of my level of comfort with the facility and other JKC clients and the amount of knowledge both Jon and Thomas demonstrate through personal attention to form, core development and overall strength is outstanding. JKC is by far the best training hands on attention that I’ve experienced period and I have experienced many over a lifetime of activity and playing various sports. The facility has everything you require plus, as you will learn there are many ways to use every piece of equipment and Jon and Thomas are very creative! There are many age groups and professions who attend this gym from elite athlete’s to the rest of us and the casual but focused atmosphere in the gym makes each visit interesting, friendly and challenging at all levels.

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.

I chose JKC because I was looking for something different. I’ve seen and done the trendy workout programs before, I was looking for something that I knew I could see myself still doing a year from now! JKC has a lot of clients that have been going for years. That was a huge motivator for me! The small group coaching sessions are great and I really enjoy the format. It’s nice having 2-4 people working-out with you during your session. The camaraderie is great, everyone is very upbeat and positive – zero gym judgment!
