Mr Josiah armstrong & Mrs Susan Michelson

I am the founder of Forerunner Fitness, School of Warrior Arts, and I serve on the senior leadership team of The Crossing Life Church in Windham, NH. I love the martial arts for many reasons, but I love people more.  My goal is to add value to your life and empower you through the martial arts.  I truly see our training and methodology as holistic education for life.  Everything you learn on the mats will be applicable for life, whether you're 4 years old or 60 years old.  We train the Body, but more than that we train the heart and the mind!

I am presently a 4th degree Black Belt in Uechi Ryu and proficient in various other arts that are incorporated into the school. I am also a Certified Personal Trainer, Holistic Wellness Coach, & John Maxwell Certified speaker, trainer, coach.
       I live in Derry, NH with my wife, Crystal, and three children, Jubilee, Asher, & Legacy.

I am Mr Armstrong's senior student and Assistant Instructor.  With a brief introduction to martial arts in early adulthood, I am very thankful to have found SOWA at this season of life as it's been a tool to push me forward in every way of my life.  Studying a martial art has facilitated many of my passions to work cohesively together: mentoring, equipping, and empowering students of all ages unto health in body, soul, and spirit.  I wholly believe in and carry the vision our school.  I feel very privileged and thankful for the opportunities given, for relationships discovered, and for the shoulders upon which I stand in my journey.


I am presently a Shodan (1st Degree Black Belt), a local business owner with my husband, a homeschooling Mama, and part of the Crossing Life Church community leadership teams.  My family and I reside in Windham, NH.
