Matt Leu
M.S. Kinesiology
Owner & Lead Coach
Matt has been an endurance athlete since the age of eight, starting with junior triathlons and competing across multiple sports through high school. He has raced distances from 5K to Ironman, including: half-marathons, marathons, running a rim-to-rim crossing of the Grand Canyon, and a competitive Ironman personal best of 9:54.
After a brief stint as a business major, he found his way into exercise science when a faculty member invited him to work at the campus fitness facility, where he first learned to build training programs by coaching real people through them.
He holds an A.A. from Santa Barbara City College and a B.S. and M.S. in Kinesiology from Cal Poly San Luis Obispo.
A turning point in his career came while teaching human anatomy at San Diego City College. The cadaver lab reframed how he thought about education itself; not just what to teach, but how to make knowledge applicable. Kinesiology is a degree most people in the industry quietly consider a dead end. He built a gym that requires one.
Matt oversees every client's exercise programming at San Pedro Fit Works and personally mentors every trainer on staff. He develops the studio's endurance and event training methodology and maintains an active coaching role with complex and performance-level clients.
