Coach Chung Sun

Chung Sun

Chung Sun grew up in San Diego and has always been an avid athlete. Raised in a household with three boys, he played every sport under the sun including basketball, hockey, football, wrestling and golf. His passion, however, was always towards mixed martial art and strength and conditioning training. In 2009, he was introduced to his first functional fitness workout, Cindy, by his cousin who is a Marine. Having always excelled in fitness and endurance, he was humbled after 4 minutes of work and was on the floor gasping for air. Not one to shy away from defeat or a challenge, he instantly noticed a huge deficit in his fitness and dedicated to learning more and training under the functional fitness method. His thirst for knowledge and his love for sharing quickly transformed this hobby into a life long passion. Chung is an avid student when it comes to everything health, and functional fitness related. Seeing the transformations with himself and many clients from all walks of life, he now dedicates his life to teaching people how to achieve their health and fitness goals.
