Personal trainer
Level Up Fitness
Training is about more than just the physical. When you talk to someone, you are training your mind to realize that you aren't alone. As a trainer, when a client trusts me with their story, it makes the job worthwhile. It isn’t just a career or a financial path; it’s a journey that fulfills me both mentally and physically.

Biography
Defterios is an HRD Corp-certified trainer and a senior personal trainer at LevelUp Fitness in Kuching, Sarawak, where he has spent over eight years helping clients transform their lives. Holding a Bachelor’s degree in Sports Science, Deft combines deep academic knowledge with practical experience to provide more than just workout routines; he specializes in rehab, posture correction, and strength and conditioning (Level 2).
His path to fitness was unconventional—originally a dedicated student who avoided sports to focus on academics, he chose Sports Science primarily to escape mathematics. Inspired by the resilience and storytelling of professional wrestling figures like John Cena, he developed a passion for "teaching through fitness."
Deft is particularly noted for his work with senior citizens—his oldest client is 82—and his firm stance on "health-first" training. He is a vocal advocate against the use of performance-enhancing drugs (steroids) in commercial gyms, believing that fitness should be a "circle of positivity" that enhances longevity and mental well-being rather than just chasing a shortcut to a specific look. Beyond the gym, he is also qualified to lead corporate team-building and leadership programs, bridging the gap between physical vitality and professional performance.
