ISSA Certified Fitness Instructor
Low Back Injury Prevention and Rehab Specialist

Hi, I'm Matt. My passion is working with people of all ages and abilities, but especially those who are ready for a lifestyle change. Getting fit, healthy and lean is a process that requires you to change your lifestyle so that those changes will stick with you for the rest of your life. In my own personal struggles, my weight ballooned up to 260 pounds! I can thoroughly sympathize with what you are going through; how out of control and in despair you may feel. Just like you, I coped with stress by overeating and could not see the damage I was doing to my own health. It took the intervention of a good friend to turn my life around. In 2008 I became certified by the ISSA as a personal trainer.

I want to show you how to build a body that is strong; that is functional and healthy enough to meet the demands of your day and still leave you feeling energized and ready to take life on.

Matt Lesley


Working out and having fun.

Certified Fitness Trainer

After a 23-year struggle with excess weight I was determined to change how I looked and felt and began my journey towards vibrant health in a YMCA in Washington. Often I felt discouraged, but I managed to stick with it and lost 60 pounds with power lifting and body building. That gave me the self-confidence to take up mountain bike racing, road cycling and my true passion: Trail running. In 2002 I obtained my certification from NASM (National Academy of Sports Medicine) and have been working as a personal trainer in Sonoma County since then.

I specialize in functional training methods, meaning that these methods can be applied to everyday movements and activities. In 2009 I expanded my love of health and healing by becoming a certified massage practitioner. I love working with people of all ages and abilities, boosting their self-confidence with compassion I gained though my own struggles. What are your issues and goals? Let's have a chat.
