I have been working out at CORE Strong Fitness for over a month now. Within the first month I have seen changes in my body and motivation. Mark is not only there to coach you through the workouts, but also there to help motivate you to change your body and mentality towards working out. He truly cares about each client and is there for anything you need. I look forward to going to the gym everyday. You will work hard but you WILL have fun!

This is the absolute best place to be. Not only did I do the 90 day challenge and lose 27 pounds, but I also learned how to do it the right way. Which means.. I’m still losing weight 3 months later, and I am continuing to feel good, healthy, and STRONG. Mark is amazing, he’s the best fitness coach I’ve ever had (and I’ve had quite a few). As a former athlete, I truly appreciate his balance between motivating and supportive. He knows his stuff which is awesome because you never have to question the process. I highly recommend trying this amazing facility. Love my CORE Strong family!

Mark helped me get strong and fit for a climb to Mt Rainier in the state of Washington. Mark will motivate you and push you to become stronger and will give you the BEST advice on form and posture. The CORE strong family is also very awesome and welcoming!

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!

After being a runner all my life, I found recovering from knee surgery to be one of my biggest challenges. Mark helped my progress with his careful modifications and TRX strength training. As he observes your ability, he knows how to challenge you without regression.It feels great to be strong again!

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!

The Ultimate full body workout. I was so nervous at first..I was certain I would look like a fool. I didn't!! Mark who is the coach is so passionate about what he teaches. You feed off of that and can't wait to get to another class. If you do get nervous with classes he does private sessions..however I have a feeling once you get the basics down you'll be excited about joining the Core Strong family. Earn Your Better!!

Tried TRX after an injury to regain strength. I've gained it back and then some! Mark is great. The workouts will always test new muscle groups. You WILL find muscles you never knew existed!

Having gone 4 times now I feel like every time has made me want to go even more. Mark has been a blessing, he gives personal attention and is always there with an encouraging word. TRX is a great full body workout. I am coming from no exercise at all to enjoying myself doing TRX with Mark and anyone else who shows up. It's been a great experience. Give it a try, you won't be disappointed!

I went to improve my upper body strength and got so much more. I've been going for 8 months and continue to look forward to it every week. Our trainer, Mark, goes above and beyond to ensure a great workout. His knowledge and experience allows him to give each individual the best workout for their fitness level. Class is like getting together with family.
