My name is Johnathan Sexton, founder of OneChristianMan and Flesh Tamers Fitness. I’m passionate about faith, family, fitness, and technology—and I’m blessed to live in the U.S. with my wife, two incredible kids, a few backyard chickens, and a love for college football Saturdays.
Professionally, I bring over 22 years of experience in Information Technology, having served as a programmer, project manager, senior manager, principal technical program manager, and now director. I’m a certified Project Management Professional (PMP) and Certified Scrum Master (CSM), with deep experience leading large-scale programs in one of the world’s most complex corporate environments.
Outside the tech world, I’m a certified NASM personal trainer, with additional certifications in Performance Enhancement, Sports Nutrition, and Behavior Change. Fitness isn’t just a hobby—it’s a discipline I pursue to strengthen my calling and serve others with energy and endurance. Additionally, I am a certified member of the Maxwell Leadership Certified Team.
Whether it’s weightlifting, running, coaching others, or hosting fitness challenges, I see physical health as a way to extend and amplify the mission God has given me: to share the Gospel, lead with excellence, and help others grow in faith, strength, and purpose—for as long as He gives me breath in this flesh tent.
I’m a follower of Jesus Christ, and everything I do starts with that foundation.
I created the Flesh Tamers Fitness program to help men and women not only lose weight but also become heart-healthy, build lean muscle, grow in confidence, and strengthen their bodies so they can fully pursue the mission God has placed on their lives.
This isn’t just about physical transformation.
It’s about stewardship.
It’s about discipline.
And it’s about using our strength for God’s glory, not our own.
My purpose:
“To lead with excellence, integrity, and faith — empowering individuals to grow spiritually, mentally, and physically through Christ-centered coaching, impactful writing, and transformational leadership. I strive to steward my God-given gifts in technology, fitness, and communication to build strong men, resilient teams, and enduring legacies for the glory of God.”
