Dr. Michael Yessis
6/16/32-9/15/23
Born in NY to immigrant parents, Dr. Yessis was a pioneer in the fields of biomechanics and kinesiology. He was the first to bring Soviet sports training to the United States and then build upon those theories in his own work with athletes. He taught at CSUF for many years, training many students in biomechanics and kinesiology. He authored a longtime journal, the Fitness and Sports Review along with 17 books and over 2500 articles.

Dr. Yessis developed many unique sports-specific exercises and specialized training programs to improve technique, strength, flexibility, power, speed and quickness. His training program, now known as the Yessis System of improving performance, consists of biomechanical analyses and the creation of specialized exercises that duplicate what the athlete must do in ex*****on of his sports skills.

He is survived by his wife of 44 years, Edie, his daughter Marissa Yessis Prough and grandson, Declan Prough.
