James Harris
Founder
James Harris opened Brentwood Barbell in 2016, driven by a desire to help people dramatically improve their quality of life through exercise and nutrition. Brentwood Barbell has always been about creating an atmosphere where Strength is for Everyone!
This inclusive idea has created a community of like-minded people centered around the elegance and simplicity of basic barbell training. James found barbell training in an attempt to rehabilitate is knees after his playing days (basketball) had long-since finished. When nothing else seemed to work, getting stronger did
All through physical therapy school, James knew his mission was going to be to provide a seamless transition between the fields of rehabilitation and strength and conditioning. To provide this transition in a way that made sense to people and got them the results they needed.
To James, performance and rehabilitation are the same, they simply represent different entry points. These days, Brentwood Barbell is THE place to go if you’re new to strength training, want a customized and guided approach, or want to finally see the results you’re looking for.
James has a Bachelor of Science degree from Southern Illinois University at Edwardsville. An additional Bachelor of Science degree in Exercise Science from Maryville University, and finally, James has his Master of Physical Therapy from Maryville University. In addition to building, owning, and operating Brentwood Barbell, James is a licensed physical therapist in the state of Missouri.
