Austin S.

I lost 30.5 lbs, and in the last 90 days, I lost 32.5lbs and 7.9% body fat. 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. Thank you Mark for changing my life and all my friends and family for the support and encouragement! If you want to make a change in your health, I recommend you see Mark at CORE Strong Fitness!

TRX quickly became my favorite way to exercise because Mark is an excellent coach and encourager. He helps you get the correct form so you can get the most benefit from your time at Corestrong. I love being a part of the CORE Strong family! I can't believe the change in me, not just on the outside, but on the inside as well! Getting to this point and continuing on is something I have desired for myself my entire lifetime and I am incredibly grateful to be a part of CORE Strong Fitness!

Mark is my hero! He’s a great trainer and is helping me become a bit less heavy! If you are looking for a great trainer who makes working out fun and effective you need to connect with him! Also, he helped me to get my core strength much stronger and my golf game proves it!

At the end of the day, he's my friend first, which makes this success even sweeter. His wife Stephanie Campbell was with me every step of the way. She shares in my success. I hit the Trx classes usually four to five times a week, before work at my 5am, learned to know when I was full by eating correct portions, and learning to eat without emotion. My entire life improved starting with my self-confidence. My marriage improved. My relationships with others improved. I was honestly just happier. People noticed. Week by week I was getting results and falling in love with my life again. I lost four inches off my waist, about 2.5 inches off my thigh, half an inch off my arm, about 11 pounds and dropped my BMI by 2.2. Here's to you and your 90 day bad ass program. Cheers to you Mark Campbell for improving my life and my waistline

I worked out HARD for a year but wouldn't REALLY change my diet the way I should have. I lost 15 pounds during this time and despite an old back injury resurfacing, I gained quite a bit of muscle, strength and stability. In ninety days, I lost another 26 pounds, bringing myself back down to 144 pounds of super lean muscle, as well as extreme fascia(look it up) and muscular strength. In a year, I lost 15 pounds on my own. Then, in NINETY days, I lost 26 pounds with the CORE90 program at CORE Strong Fitness! Diet is EVERYTHING. I am not even kidding.
