Brandon Brigman

Brandon grew up in Snellville, Ga., where he played a variety of sports growing up. At Shiloh High School, he was a two-year varsity letterman in football and three-year letterman in wrestling.

Brandon played college football at the University of West Georgia where he was a member of the 2000 Gulf South Conference championship team and was a two-year letterman. Brandon earned his Bachelor’s degree in Mass Communications and a minor in Sociology.

After starting CrossFit in January 2010, Brandon received his CrossFit Level 1 certification a year later. He has experience coaching beginner athletes and high-level competitors. Brandon has been coaching at No Excuses since 2011 and was named the General Manager in March of 2014. Brandon took over ownership of No Excuses CrossFit in August 2018. Prior to working full-time at No Excuses, Brandon worked as a sports writer for the Gwinnett Daily Post, covering prep sports.

In Brandon’s own words: “Once I went through my first CrossFit workout, I knew that was the workout regimen for me. It combined all the workouts I was used to and added new, fun, exercises to it. CrossFit allows me to compete with myself, others in the gym and the clock.  I’ve lost more than 60 pounds from when I was a college offensive lineman. Many of my weightlifting numbers are similar to when I played football. The biggest difference is the addition of multiple pullups, pushups and situps to my workouts.”

“Make it the best hour of your day, stay safe, turn up the music, high five some people, and blow off some steam.”

Most of us are just looking to feel better, improve our quality of life, and have a good time doing it.  Crossfit allows all of those things, and without you realizing it you notice little things, your stress levels go down.  You sleep better.  Your mood improves.  The list goes on and on…if you’ve never been involved in the community, please don’t let someone’s opinion of Crossfit undermine what you can achieve here.  I look forward to working with you!

Yessica strongly believes that CrossFit is the best program for anyone wanting to improve their health and quality of life. Ever since she started she is not only stronger physically, but mentally. Yessica wanted to pass the same CrossFit passion to her teen daughters. They both began training at No Excuses in the Teens classes.
