Brennan Fitness Academy was founded on the belief that fitness is more than a workout - it’s a lifestyle built on balance, education, and sustainable progress. Led by Southern California native Nathan Brennan, a certified online trainer and Glute Specialist, the academy combines evidence-based training and personalized nutrition guidance to help clients achieve lasting results. With a Bachelor of Science in Exercise and Wellness from Brigham Young University (BYU), Nathan brings a deep understanding of fitness science and real-world coaching experience to every client he mentors.

Nathan’s professional journey includes working alongside BYU’s Head Strength and Conditioning Coach, teaching TRX® and Bootcamp classes in Arizona, and assisting patients in physical therapy exercise rehab. These experiences have shaped his holistic coaching approach - one that emphasizes strength, mobility, and overall well-being. Outside the gym, Nathan enjoys hiking, exploring national parks, and traveling with his wife, Whitney, all while staying connected to his roots as an avid supporter of BYU athletics.
