Born with the brittle bone disease known as Osteogenesis-Imperfecta, Jeff Black has defied the odds and believed in himself to accomplish impossible. As a fitness coach both online and at Iron House Strength and Conditioning, he believes that you can be your own hero.

Osteogenesis Imperfecta (O.I.) is a rare genetic disorder characterized by bones that break easily, often from little or no apparent cause. The disease affects roughly 25,000 people in the U.S. Depending on the severity of the disease, and those afflicted may have just a few or as many as several hundred fractures in a lifetime.


By the time he was fourteen years old, Jeff had endured eighteen surgeries on his legs to allow him to walk. His journey into health and fitness began the moment a physical therapist handed him a weight to help make his upper body stronger to utilize his wheelchair and crutches better. From that moment, he was hooked on the empowerment working out gave him, and he knew his life would never be the same. He knew at a young age that if he gave his all, he could accomplish anything. Walking, without any aids, would be his first accomplishment.


Since then, Jeff has continued to defy the odds by competing in bodybuilding since 2006. Each year, he steadily improves his physique and conditioning, having placed in the top 5 in all his local and regional shows with his highest placing nationally in 2017 Junior Nationals, having earned 2nd in his weight class. In 2013, Jeff linked up with Jason Theobald, who has remained Jeff's coach and developed into mentoring Jeff.


 Jeff understands that when a person has belief, passion, and grit, anything can be realized and accomplished. When those three collide,  great things happen, and Jeff tries to create this for each of his clients. Passion for their goals. Belief in themselves. Grit to accomplish anything. Jeff prides himself on his top-notch customer communication and care. These two are critical to accomplishing and achieving the best you, no matter your goal.


Currently, Jeff is a personal trainer and fitness coach with clients both online and in personal training sessions. With over 15 years of experience, he has enjoyed working with his clients on their journey to improve their well-being with healthy dieting, nutrition, and fitness training.

Jeff owns a gym in Hermitage, TN, called Iron House Strength and Conditioning where his goal is to create a facility that is a "fitness factory" appealing to everyone. Diversity is the cornerstone of this facility, a place where all are welcomed and encouraged.


Jeff believes that health and fitness are the most important things people should strive to control to live fulfilling lives. As Jeff always tells his clients, "To make a healthy change not only physically, but mentally as well, you must be relentless to making this happen for you. Empower yourself and become you unapologetically. It is time to look at yourself in the mirror and be your hero.”


Jeff has a student heart and a real passion for pursuing continued knowledge, education, and wisdom through various and opposing points to understand key concepts to create an impact in his community and with the community at large.
