Alex Barrett is a 9-year NFL veteran, spending the majority of his career with the San Francisco 49ers, with prior stops with the Detroit Lions, Oakland Raiders, and the San Diego Fleet (AAF). His path to the NFL was built through discipline, resilience, and a relentless investment in himself—especially in the weight room. For Alex, training wasn’t optional; it was his competitive edge.
As an undrafted free agent fighting every season to earn or protect a roster spot, Alex learned early that the work you put in when nobody is watching determines the player you become when everyone is. His longevity in the league wasn’t luck—it was process. It was preparation. It was a training system built on world-class strength methodologies.
“What you do in the weight room has a direct impact on the season you have. It’s just as important—if not more important—than the season itself.”
This philosophy—the foundation of Alex’s entire career—is now the foundation of Barrett Performance. Today, Alex brings these elite systems to athletes and clients of all ages. Whether you’re a high school athlete chasing college opportunities, a collegiate athlete preparing for a professional future, or an adult who wants to reclaim their strength, energy, and confidence, Alex teaches the exact blueprint that carried him through nine seasons in the NFL.
