Client Reviews

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

After my children were born, I was completely out of shape. I had been active before my first pregnancy in 2008. I saw a post on social media about a charity event that was hosted at the gym. It prompted me to check out the JKC website. I was immediately impressed by the professional content and decided to give it a try. The professionally crafted and uniquely tailored work outs, as well as the sense of accountability and commitment that they foster. I have not missed a workout since joining – contrary to other experiences I have had when purchasing gym memberships. The flexibility of booking and rescheduling workouts, made easy by an online app, also contributed to my success in meeting my fitness goals.

I enjoy every session, working out with Jon, Thomas and Craig, as well as the “JKC Community”. Anytime someone achieves a personal best, I enjoy the celebration and support everyone gives each other. For me, I fondly remember achieving personal bests on bench press, chin ups and the sled push, in particular.

I am turning 67 next month and I started my journey with JKC in 2018. Seven years ago I experienced significant foot pain which had a negative impact on my day to day activities. I learned that issues in other parts of the body need to be addressed to achieve a positive result. My doctor (Dr. Jessica Wade) suggested, along with some other therapies, that I could  benefit from the conditioning JKC had to offer. I previously had not trained in any gym. I observed how many gyms operated and had a sense that JKC would be more my style: training in a small group setting, having such personal attention, and a program meeting my specific needs is fantastic! I love the atmosphere at the gym. Everyone is accepted and you feel supported and comfortable.

I started at JKC because my colleagues that go to JKC all look and felt fit and healthy thanks to Jon and Thomas – if JKC helped them, I knew they could do the same for me! I think JKC stands out from other gyms because of their personal touch! They listen to you and help motivate and support. They always believe in my ability progress and learn new exercises. I’ve been training at JKC since January of 2019 and recommend them to anyone looking to learn how to lift weight properly, feel stronger, and improve their health.

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.
