Scott McWilliam

Co-founder of Lateral Fitness and founder of Muscular System Solutions.  Scott has been involved in the fitness industry since 2004, but has been involved in sports and exercise his entire life. He made a life changing decision his sophomore year of high school to loose 75 pounds. Scott realized his love of weight lifting in his senior year of high school after his baseball and swimming career ended cause he needed something to keep his weight in control. 

This was the beginning of his life calling. He dove head first into working out and competed in his first bodybuilding competition in 2003, winning his weight class. What goes up must come down. Scott's bodybuilding career came to a screeching halt with a back injury. After his back was "healed", he decided to make his career official and attend NPTI in 2004 and obtained his first personal training position at Fitness Formula Club (FFC) in the Gold Coast. As his hours and the demand on his body increased he was continually plagued with a constant back issue, which interfered with his workouts. He was introduced to massage therapy shortly after his hire to FFC. Scott had good results allowing him to get back to lifting, so he decided to become a licensed massage therapist to understand the muscular system more to help his clients. Massage was the tip of the iceberg in his education. Scott then learned about Greg Roskopf’s Muscle Activation Techniques™ which focused on improving muscular function, between 2009 and 2013 he not only became a MAT Specialist, but he received his MATm and Mastery as a Resistance Training Specialist™. 

Scott's back problem was finally resolved from getting regular Muscle Activation Techniques treatments and adopted a new mindset on exercise. By learning how to slowly improve muscular tolerance and realizing workout is a marathon not a sprint. His back is stronger than ever. Scott's passion to understand the muscular system is endless. He is continually striving for excellence.
