Its a great class thats more strength oriented than cardio, though it did get my heart rate up. The emphasis is on form and quality reps- the instructor is great about answering questions and giving you guidance. Its a great way to start a Friday morning!

I have been going to Core Strong for a couple of months now. The classes are challenging and never routine. The coaches will suggest modifications if needed and push you when you need that too! Going to a new gym can be intimidating, but I can honestly say that I have felt welcome from day one. I really enjoy the comradery of the coaches and members. It may sound cliche but this is a gym family, they truly care about one another, not only at the gym but outside the gym as well. Everyone is encouraging and the accountability keeps me going back. My original goals were to get stronger and improve my balance and I’m proud of the progress I’m making.

I've used ClassPass to visit CORE Strong Fitness and I've loved them. It's a great facility, offers challenging workouts, and motivational coaches. If you are in the KC area I would recommend checking them out!

Adding to my review to share how great the new facility is - I've been attending in person classes for the past year. Walking into the atmosphere at Core Strong KC is unlike any other. It's super clean, organized, and designed so you can get right to business with your workout.

I went from attending classes once weekly via ClassPass to becoming a full member and working out with CORE Strong KC daily. The new gym space really puts them over the edge.

Hands down best gym in KC. The variety of classes throughout the day give you all kinds of options to come in and get your workout. Coaches are all amazing and do a great job not only pushing you but also making sure you are correctly doing the exercise to prevent injury. I’ve been coming here for three years and I have never felt burnt out, always something new you can do to challenge your ability.
Facility is clean and very well maintained. Great lighting and a fun filled atmosphere. You come in as an individual and you leave feeling like part of a family.

They will notice you struggling and stop their circuit to assist you. The class instructor is also walking around to assist anyone having trouble or needing some extra guidance.

CORE Strong Fitness has been THE most encouraging and goals-based gym I have ever been a part of. Mark and Stephanie are simply two of the finest individuals around. Not only does their physical strength and endurance show that they practice what they preach, but they are so good at passing the excitement of achievement on to others. All of their classes and programs are mixed with their positive outlook and encouragement.

I have worked-out with trainers in the past and believe that Mark is one of the finest among them I have never been pushed so far, believed in myself so much, felt so strong, nor achieved such a high level of strength before. Because of these things, I will be a life-long supporter of CORE Strong!

CORE Strong fitness has completely changed the way I workout and I'm so much better for it! If you are looking for something that will strengthen your whole body, this place has got it! Mark Campbell is an incredible and well educated trainer and classes are so much fun! I was introduced to TRX suspension training when I set a goal to run my first half marathon. Within the first few sessions I could already tell a difference in my strength and my running. Injuries stopped holding me back and I started enjoying training again. I completed my race and continue to set new PRs for myself as I get stronger. I have done personal training as well as classes with Mark and both have been an amazing experience. No matter what goal you are trying to reach, CORE Strong Fitness will challenge you and encourage you to keep going while you learn new ways to get there! I seriously suggest trying it out!

I can't say enough wonderful things about Mark (Core Strong Fitness) and his TRX training! As someone who's been altletic my whole life I can honestly say this is the most fun, team spirit, complete body, insane results type of work out I've ever done. Don't get me wrong, you EARN IT, but it's a very encouraging atmosphere and Mark's extensive knowledge of the body, muscle groups and even diet (my husband and I do his 90 challenge/diet and have seen INSANE results, all while still eating great foods!) is worth so much more than you could ever pay. Knowing him and being a part of the core strong family has been life changing. The least you can do is check out a class and I encourage you to comit to one month and see how your life changes!
