“The biggest change was the diet. If you truly want to become healthier and get in better shape, you must have a combination of diet and exercise, not one or the other…I went from a size XXL/XL shirt at the beginning of the year to a sie M!”

Hi, I'm Mark!

I’m the owner and lead coach at CORE Strong Fitness. We’re a small gym, with personalized attention that gets results. I’m in the gym every day. You’ll see me teaching classes, coaching clients and throwing out a dance move or two.

I have more than a decade of personal training experience, and expert certifications that few trainers have in the Midwest. Couple that with my passion for fitness and health, and you have the ingredients for success.

If you give me 90 days, I’ll give you the tools that can transform your life forever! It’s more than just amazing before and after photos. The CORE90 Challenge is about reigniting that spark on the inside too! I know how it feels to be healthy and strong! That’s what I want for you too.

I enjoy rock climbing, hiking, learning, teaching and spending quiet time at home with my wife and dogs.

Mark is my hero! He's a great trainer and is helping me become a bit less heavy!

FAQs

Will I be able to do the workouts if I'm not in shape?

Yes! We provide modifications for every exercise, based on your fitness level. Most of CORE90 challengers haven’t worked out in awhile when they join our program.

Kristin joined us at age 40, and in her words “completely out of shape.” She couldn’t do many of the exercises. “Mark was fantastic and gave me a good heart to heart. I decided at that moment I was giving everything.” She lost 8 pounds in 90 days and gained a ton of confidence.

When you commit to making a change, you’ll get your body back!

What kind of workouts will I be doing?
