Client Reviews

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

I had virtually no real experience using weights and felt intimidated going gyms. I avoided gym-goers using free weights, especially when hearing that loud crash, as they would drop weights to the floor. I thought this was to show everyone around them that they owned that area and that I shouldn’t go anywhere near! So I guess I just wanted to learn how to lift weights safely in a gym environment.

I spent over 18 years in the British Military, so I got to use some nice gyms. 99% of my time and experiences in those gyms was spent doing cardiovascular workouts, because I could just jump on a treadmill, plug in my head phones and do my own thing! JKC is different, because they have given me the confidence to use free weights and equipment that I had feared for years. Their demonstrations and knowledge is impeccable and I thank them for their continuous belief and support they show me at every session.

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.

I started strength training at JKC in the Spring of 2021. I am in my 60’s but happy to say I feel much younger since joining this gym. I joined JKC upon the advice of a doctor. I went through some difficult medical issues last year, that’s when one of my doctors recommended strength training at JKC. I have been physically active most of my adult life but mainly running and completed many road races as I am a distance runner. Strength training has definitely benefited me by increasing my stamina and energy. It sure has enhanced my recovery over the past year. I have the added benefit of becoming a stronger runner as well.

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. 👏🙌👍👊

I heard really good things about it from my sister, and I could see the positive results she was getting.  I needed to do something.  I was overweight, depressed, and recovering from a back injury.  I had reached a point where simply getting up out of a chair was becoming difficult.  I knew that if I didn’t do something about it my senior years would be very burdensome to the people close to me.  I’m so glad I did!  After just a few weeks my day-to-day pain was drastically reduced, and my mobility increased. I had the confidence to try sea kayaking, and I now play ice hockey twice a week!

The key difference is the expertise.  The trainers know the gym equipment and the exercises, but they also have degrees in kinesiology, and can apply what they know to your workout.  As someone who was in poor physical condition starting out, I was worried about hurting myself.  Previously I tried an outdoor weekly bootcamp and injured my knee by pushing too hard.  The trainers at JKC constructed a program that started at the right level for me, evolving it as I grew stronger and more fit.  I feel well looked after.
