I would challenge anyone to find a better experience.

Fantastic experience: Smart, professional, and flexible hours for guided workout sessions. Friendly and fun coaches. Their knowledge about how to maximize your efforts is excellent!

Fantastic experience: Great coaching, great workouts, great gym. Coaching takes its time to work with each individual on areas they need to improve. The workouts are only 50 Minutes, but you feel like you Adequately targeted a muscle group after every class. The gym is small, but has everything you need with the coaching and structure to provide a great workout while also giving it an individual hands-on experience

Fantastic experience: This is the best gym! I joined JKSF about 3 years ago (at this point). I really did not know what I was doing in the gym -especially with weight training. Weight training was a whole new concept to me. I felt welcomed the moment I walked in the door. The owner, Jon is a very personable person, was able to answer all my questions and made me less apprehensive about trying something new. Jon is very encouraging, knowledgeable and is an amazing trainer/teacher. He teaches you proper form first and always encourages you to do your best. Since joining JKSF there have been some new additions in coaches who are also knowledgeable and encouraging. No matter if you’re just starting out in this journey or experienced, I highly recommend JKSF. Knowledgeable, friendly staff who are always willing to assist. JKSF has become my gym family!

Fantastic experience: Friendly, highly-knowledgeable coaches who will help you achieve your goals no matter your fitness level. You’ll get a good workout every session and train alongside a diverse group of fun people.

Fantastic experience: Having lifelong spinal issues and other pain because of that - JKSF has been the only gym I’ve encountered that knows how to not only help me work with the issues I have but, to also help me do it pain free.

Fantastic experience: This gym has far exceeded my expectations. I am part of a true community here and look forward to working out now! The trainers are absolutely awesome, everyone knows you by name and your level and actively watch and tweak your form so you know you are doing the exercises correctly and they help push you to the next level. I have also received diet guidance and that paired with these workouts have been incredibly effective for me. It is small group classes which is helpful and you get that personalized trainer experience. So glad I found JK Strength and Fitness!

Fantastic experience: Jon and staff have been amazing helping my athlete on his journey to becoming the best he can be. They take the time to make sure you are doing it correctly as well as push and motivate you to give it your all. Keep up the good work.

Fantastic experience: This is by far the best gym I’ve been apart of. The sense of community starts at the top with the owner, Jon. He has created such a unique and enjoyable environment, one I’ve never experienced in other gyms. He is a fantastic trainer and truly knows how to get the most out of people. He will challenge you and push you further than you thought you could go. I cannot recommend this place enough and tell everyone about it whenever I have the chance.

Fantastic experience: I am 51 years old and post bariatric bypass surgery . The next step in my journey was strength training. I needed to find the right place, the right atmosphere and most importantly the right people! And I found all of that at JK Strength and Fitness!! They took the time to understand my situation and have worked with me closely to work thru my limitations. The team at JK , Heaven, Noah and the big dog himself, Jon are simply the best at what they do. I can’t tell you enough the impact they have made on my attitude, my confidence and overall health.

Fantastic experience: I was in Villa Park visiting my in-laws and needed a place to work out. I'm glad I found JK Strength and they allowed a drop in. I haven't been working out for long and just followed the plan from my trainer back home. Jon gave me some pointers to try out on my squat which have helped a lot. I really enjoyed the 'vibe' of the place. It has a nice blend of fun and seriousness.

I love being pushed and told to keep going when I want to quit! I truly appreciate this past month and I can’t wait to keep coming!

Fantastic experience: I have been a member of JK Strength and Fitness for 3 months now and could not recommend this gym more. Jon truly is able to bring personal training to group classes and cares about each and every one of his members. He first hand knows every members lifting ability, their maximum weights on each exercise and the correct recommendations for each skill level. You can tell that Jon is very knowledgable at what he does and cares about each and every member. 

I have felt welcome every single time I step into the gym, especially by his fiancé who greets everyone and always has positive energy. I love coming to come to a place where I am excited to work out, don’t feel judged and have developed friendships.

Fantastic experience: While I may live out of state, Jon has been an incredible help in my fitness journey! His plans are made for whatever you have to use while still getting the full affect -- whether it be home workouts with little access to equipment or full on gym activity. Jon is easy to communicate with, always there to answer questions, make recommendations, and talk through specific exercise needs. I highly recommend checking out his gym or reaching out for a plan, you won't regret it!

Fantastic experience: I joined in the summer during my summer break and it was honestly the best three months ever. I signed up for multiple different gyms in my life and never really knew what I was doing. When I signed up for JK Strength and Fitness I learned so much about myself and my body.

Fantastic experience: I joined JKSF about 6 weeks ago. I decided on this gym, even though I have never done anything like this before. I am older and didn't think it was for me. I'd drive past on my way home from work and thought it was some He-man weightlifting club. Then I saw a whole variety of people working out here and they looked like they were having fun! Well, that got me curious, so I stopped in and arranged for a trial workout day. First, the people here are so great to work out with and so encouraging. I have been to other gyms, clubs, classes, etc and there was this underlying completive feel. None of that here! I have to believe this whole attitude comes from Jon, the owner. This guy knows his stuff when it comes to fitness and nutrition. But then add on the fact that he is one of the nicest people I have ever met in this industry, and you get this fantastic coach! I look forward to going and working out. That bears repeating... I look forward to going here! I can't wait to see what happens to my body in a year!

Fantastic experience: Jon has been the best coach I’ve ever had. He is highly educated and extremely knowledgeable in fitness, nutrition, and overall body mechanics. He motivates you to be your best self everyday and ignore that little voice in your head that wants you to quit. Since joining JK, I have gotten stronger, seen improvements in my form, and have made awesome friends. JK has created a supportive community where all levels are welcomed.

Fantastic experience: JKSF is such a fun and safe place to workout! Jon has done a great job with the space and tailors the workouts for a very personalized experience every time. I love coming here!

Fantastic experience: JK Strength and Fitness is an awesome gym! Jon has a ton of experience & individualizes workouts based on your needs. He is very professional & a great communicator. The gym and equipment is in great shape, very clean, and up to date. I would definitely recommend visiting JKSF & working with Jon!

Fantastic experience: Ask for Jon... He will setup the right training for you.
