About Fitz Fitness

Fitz Fitness was founded on a simple principle: training should be personal, purposeful, and proven to work. Since launching over five years ago, we’ve helped hundreds of clients across Charleston gain strength, improve mobility, and unlock their full potential through expert-led, results-driven programming.

We’ve never been about fads. We’re about building real, sustainable success—one session at a time. Now, with the opening of our new location on Johns Island, we’re taking things further. More space. More services. Same commitment to excellence.

MEET OUR FOUNDER, TJ

Built by Experience, Backed by Results

With over 12 years in the industry and a certification from the National Academy of Sports Medicine, founder TJ Fitzmaurice has trained clients in major markets including New York, Los Angeles, and San Francisco before putting down roots in Charleston.

His passion and the experience of every coach at Fitz Fitness shape a culture that values education, integrity, and long-term progress. From strength training and weight loss to rehab support and performance coaching, wherever you’re beginning, we’re here to help you move forward.

Jessie Schramm

Personal Trainer & Nutrition Coach

Jessie is a personal trainer and nutrition coach who is passionate about helping people build strength, confidence, and sustainable habits. Her approach focuses on progressive training, proper nutrition, and lifestyle balance—because real results happen outside the gym just as much as inside it. She believes fitness should enhance your life, not restrict it. Whether your goal is fat loss, muscle gain, or simply feeling stronger and more energized, she is here to guide, educate, and support you every step of the way. Outside of personal training, you’ll find Jessie spending time outside, finding new hobbies, and traveling to new countries.

Ryan Summers

Personal Trainer & Nutrition Coach

Ryan’s path to fitness started long before he ever stepped into a training role. At eleven years old, he survived a lightning strike that stopped his heart for twelve minutes. The recovery process required him to relearn basic skills such as walking and speaking — an experience that shaped his resilience, discipline, and mindset for life.

During that recovery, fitness became more than exercise. It became a way to rebuild strength, confidence, and control. That foundation still drives his approach today.

Ryan has completed 18 half marathons and 3 full marathons and is currently training for his first 50-mile race. His endurance background gives him a deep understanding of mental toughness, progressive training, and long-term performance development.

In every session, Ryan focuses on helping clients move better, build sustainable strength, and push past perceived limits — physically and mentally. His coaching style blends encouragement, accountability, and real-world perspective to help clients become stronger in every sense of the word.
