Brennon Pamplin
ACSM Certified Personal Trainer
CPR/First-Aid Certified

When Brennon Pamplin was eleven years old, he was diagnosed with a severe case of scoliosis and spondylolisthesis. At the time, he was very active in martial arts, wrestling, and track and field. He was told that he would have to undergo spinal fusion surgery, risking paralysis or death, by the time his body was fully mature. He refused the operation, deciding instead to devote himself to acquiring the knowledge base necessary to not only save himself but also to continue developing his athletic abilities. During this time, Brennon got involved in competitive swimming with Baylor’s swim team in Chattanooga, Tennessee, to complement his rigorous gymnastics strength training, martial arts, and weightlifting. The lower impact exercise developed his muscles without further compressing his spine.

Brennon competed in swimming all through middle school and high school and decided that he wanted to be a movement specialist and coach after graduation. This decision forced him to shift gears in his studies from rehabilitation specific strengthening to more sport specific and performance development. Five years later, he instructs young athletes in a variety of disciplines. He integrates what he has learned from various sports, athletic endeavors, and therapeutic modalities into the coaching he provides for his students, drawing parallels that help facilitate and foster the technical understanding that separates those who are good from those who are great.

Having never deviated from my foundation, and having a black belt in Tae Kwon Do, I teach practical self defense and martial arts to those who seek the capacity to handle an altercation should the need arise.

Brennon is certified through the National Academy of Sports Medicine
