With more than a decade of training experience, a demanding career as a registered nurse, and a successful debut in professional bodybuilding, Franz Arevalo is a powerful example of what discipline, faith, and perseverance can achieve.
Franz’s journey into fitness did not begin with universal support. When he first started training and going to the gym, he faced criticism and doubt from people around him—including some family members and friends. Many questioned his commitment and intentions. Despite it all, Franz remained focused on his vision. Over time, that dedication would lead him to compete in bodybuilding competitions, launch his own fitness coaching platform, and earn his place as a WBFF Pro athlete.
While building his fitness career, Franz has continued working full-time in healthcare as a registered nurse. His ability to balance both worlds reflects the discipline and work ethic that have become central to his identity.
Serving on the Frontlines During the Pandemic
During the Covid-19 pandemic, Franz served on the frontlines as a clinical lead at a Covid-19 testing station in West Auckland. Like many healthcare workers during that time, he faced intense pressure and long working hours while helping the community navigate an unprecedented health crisis.
Balancing the emotional and physical demands of frontline healthcare while maintaining his own health and fitness was a constant challenge. Yet Franz remained committed to both his profession and his personal wellbeing. He often credits the strength he finds in his faith as the foundation that helped him cope with the stress and responsibility of that period.
Turning Lockdown Into Opportunity
The Covid lockdown in 2020 became a turning point in Franz’s fitness journey. With gyms closed and normal routines disrupted, many people paused their fitness goals. Franz chose a different approach.
Using creativity and resourcefulness, he continued to train at home. Everyday household items became training equipment. Water jugs were used for resistance training, and even his microwave became part of his workout routine for weighted squat exercises. Rather than allowing the restrictions to slow his progress, Franz saw an opportunity to grow and help others do the same.
Inspiring Others Through Social Media
Drawing on more than ten years of training experience, Franz began sharing his knowledge online during lockdown. What started as a way to stay active and accountable quickly evolved into a growing platform where he encouraged others to improve their health and confidence.

Through his posts and training insights, he began reaching people who struggled with self-esteem, fitness uncertainty, and fear of stepping into the gym. Many individuals believed their past failures meant they would never succeed in fitness. Franz worked to challenge that mindset.
He firmly believes that transformation is always possible with the right guidance, discipline, and belief.
Helping Beginners Build Confidence
One of the most common fears Franz sees among beginners is weight training. Many people feel intimidated because they have never been taught how to lift properly or safely.
Through his coaching, Franz focuses on teaching individuals correct training techniques so they can lift weights confidently and injury-free. His approach emphasizes heavy but controlled eccentric movements designed to build natural muscle, long-term strength, and overall resilience.
Beyond physical training, he also helps clients develop discipline, set clear priorities, and create urgency toward their goals—skills that extend far beyond the gym.

In his first appearance in the professional division, Franz placed in the Top 3, an achievement that reflected years of discipline, sacrifice, and unwavering belief in his vision.
As a natural athlete, he continues to emphasize the importance of proper nutrition, supplementation, recovery, and structured training as the foundation of long-term performance and health.
Fast forward to 2025 and Franz would take his place in the biggest bodybuilding Pro Show in Australia. Finishing in third place and winning “Overall Best Dressed Male”.
Faith, Purpose, and Perseverance
Franz’s journey has never been solely about trophies or recognition. For him, success is measured by endurance, purpose, and the ability to positively impact the lives of others.
He often reflects on the early criticism he faced when beginning his journey. Rather than allowing those voices to discourage him, he stayed focused on the purpose he believed God had placed in his heart.
Today, Franz continues to balance his career in healthcare with his passion for fitness coaching and competition. His story serves as a reminder that even in the most demanding professions, it is possible to pursue personal growth and inspire others along the way. As Franz often reminds those he coaches: not everyone will appreciate the good in you, but if you stay committed to the process and the vision, the results will eventually speak for themselves.
His journey stands as a testament to faith, resilience, and the courage to pursue one’s God-given purpose.
