Mitchell Fischer

Mitchell Fischer, known to many as “Coach Fisch,” is the owner and head coach of OPEX San Antonio. With over 8 years of personal training experience and a Bachelor of Science in Kinesiology from UTSA, Mitchell brings both deep expertise and a passion for lifelong learning to his clients.

His journey in fitness began long before his professional career — he grew up training in martial arts across various styles and continues to practice Brazilian Jiu Jitsu at OHANA Academy in San Antonio, where he holds a black belt.

Throughout his career, Mitchell has earned multiple certifications, with his most impactful being the OPEX CCP, a comprehensive coaching certification focused on individualized fitness. Prior to opening OPEX San Antonio, Mitchell served as a Fitness Manager and Master Coach at Gold’s Gym, where he led the national programming for Gold’sFIT and certified coaches across the country.

Mitchell’s coaching philosophy is simple: fitness should fit into your life — not the other way around. He believes fitness is one of the most powerful forms of preventative healthcare and works closely with each client to design training and lifestyle solutions that support long-term health and personal goals.

When he’s not coaching, Mitchell stays active in his own training and enjoys leading by example for his family and community.
