Meet Justin Gaynor – Owner & Head Coach, Gainor’s Gains

The founder and head coach of Gainor’s Gains. With over a decade of hands-on experience in fitness, I’ve dedicated my life to mastering and applying a wide range of training methods—including resistance training, bodybuilding, dynamic stretching, and nutrition—to help people unlock their full potential.

My passion for coaching is driven by an ongoing pursuit of knowledge across all training styles, ensuring my clients benefit from the most effective, evidence-based techniques available. I hold an NCCPT Personal Trainer Certification and Nutrition Coach Certification, and I’m currently completing my Bodybuilding Specialist Certification to further enhance my expertise.

In recent years, I’ve built a strong social media presence and a growing community, all centered on teaching the importance of resistance training and proper nutrition as the foundation for a longer, stronger, and healthier life.

Before launching Gainor’s Gains, I lived abroad in Tokyo teaching English—a role that taught me how much I love connecting with people and guiding them toward personal growth. That experience inspired me to combine my love for fitness with my passion for teaching, creating a coaching approach that’s both results-driven and highly educational.

My Coaching Philosophy:

Fitness is more than just lifting weights—it’s about building confidence, improving overall well-being, and developing habits that last a lifetime. My mission is to empower every client with the knowledge, tools, and motivation they need to succeed inside and outside the gym.
