Get to know the coaches who make our Community Strong. This month we’re catching up with Coach Sergio Valadez, who joined Defined in 2015 and our coaching team in 2021.
Fun fact: When Coach Sergio first walked into a CrossFit gym, he could not do a single-under with a jump rope. Some even say he cannot do one to this day! (His words, not ours. 😂)
Hear Coach Sergio talk about his joy for coaching and his passion for helping others on their fitness journeys—with a lot of fun along the way.
SERGIO VALADEZ | Coach
he/him
KNOWN FOR: his genuine motivational approach and randomly yelling "YEP YEP" throughout the day.
TRAINING GROUPS: Friday Nights
EXPERIENCE: 3+ years coaching at Defined (since 2021), 11+ years training CrossFit
CERTIFICATIONS: CF-L1, American Powerlifting Federation Member, Spartan Race Finisher, Double Master's in Electrical and Biomedical Engineering

LOVES: sharing CrossFit's physical, emotional, and social impacts, and helping athletes get comfortable being uncomfortable.
Sergio's CrossFit journey began in 2013 when he transitioned from an unorganized Charter Fitness routine of machines and treadmills. Despite being challenged and defeated by his first workout (Annie), he committed to following the process and trusting the results would come. His engineering background at IBM, where he helps clients manage data and cybersecurity threats, informs his systematic approach to coaching. Sergio's genuine enthusiasm stems from understanding CrossFit's transformative power, and he prioritizes seeing potential in every athlete while cheering them to the finish line.
