Welcome to McGuirt Strength!

If we haven’t already had the opportunity to train together, welcome to Athletic Endeavors!

I am a Master Level Muscle Activation Techniques (MAT®) Specialist and have been a local Charleston personal trainer for over 25 years. With an extensive background in fitness, I have had the opportunity and pleasure of training top athletes in tennis, golf, baseball, and more.

Prior to earning my Associates Degree in Physical Therapy from Trident Technical College located here in Charleston, South Carolina, I received my Bachelor’s degree in Physical Education with an emphasis in Sports Medicine at The College of Charleston.

Being a fitness trainer, I like to walk the walk. I have been working for the past few months to continue to strengthen my platform for helping you get in your best shape, and am thrilled to finally bring you the new Athletic Endeavors site. Here, you’ll find everything you need to know about my gym, techniques, workouts, and the cutting-edge technology I use to help athletes reach peak performance.

I have worked in the fitness industry for 27 years, I founded Athletic Endeavors back in 2000 so that I could better help my customers achieve real, mind-blowing results by turning their health and wellness into a lifestyle. That being said, I push my clients, no matter the goal, to find athletic greatness with safe, injury-free, and effective training programs.

Whether it be safely losing weight, building and optimizing muscle, or improving hand-eye coordination to perfect your golf swing, I focus on comprehensively exercising and balancing both the mind and body. My routines are designed to integrate industry-leading fitness technology to attain peak physical performance, in addition to mental acuity, clarity, and grit.

No matter your age or fitness background, whether as a professional athlete or an aspiring one, a local team player, or an occasional gym-goer, I am ready to help you achieve proven life-altering results. All you have to do is show up.

So, get ready, get motivated, and I’ll do the rest.

To Achieving Greatness,

Mark McGuirt
MAT® Specialist & Personal Trainer, Charleston SC
