Our highly-certified and knowledgable staff are hand-selected and go through comprehensive training.
Hamoon Hosseinpour
With a background in civil engineering and over 15 years of hands-on experience in personal training, Hamoon brings a unique, structural approach to human performance. As a certified NASM-CPT, CES, and PES coach — and a biomechanics specialist — he focuses deeply on how the body moves, compensates, and ultimately improves.
Hamoon’s training philosophy is rooted in the principles of the Postural Restoration Institute, combining corrective movement with strength and performance training to help clients move better and live pain-free.
A lifelong athlete, Hamoon has competed at a high level in both soccer and beach volleyball. His firsthand experience in sports drives his passion for optimizing movement and performance in others.
He founded Pure Function Fitness after recognizing the power of truly individualized programming — and how it can transform not only fitness, but lives.
