Physical Conditioning ~ Self Defense ~ Traditional Ethics
Martial Arts & Sports ~ Weapons Training ~ Life Skills

Via Potentia is a Latin phrase that means "Path (or way) of Hidden Strength." We provide practical, no-nonsense self-defense and fitness training in a friendly atmosphere. We emphasize the value and equality of human life, conflict and injury avoidance, fighting to escape, and techniques that are not based on size, strength or advanced skills. We do not require financial contracts, long term obligations, uniforms, foreign rituals, belt fees or the like.

Quick Facts

Adult, Youth and Family Classes (age 13 and up) meet on Monday and Wednesday from 6:30 to 8:00 PM. This is the complete Via Potentia conditioning and self defense curriculum.

Open Gym runs on Fridays of every week from 6:00 to 9:00 PM. The gym is open for personal practice, sparring, and personalized instructor assistance. Any currently enrolled student may participate for free, and may bring a guest. Other drop-ins are $5. Optional First Aid, CPR and Gun Safety topics are sometimes offered during the first hour.

The Free Public Seminar on physical conditioning and self defense is held during the open gym on the last Friday of each month (6-9 PM). Bring a friend or family member, wear comfortable clothes.

New terms start each January, April, July and October. It is best to start at the beginning of the month, but it is okay to start late; we'll help you catch up. Your first two weeks are a no-obligation "tryout" period.

Our techniques and exercises include comprehensive sparring and grappling, heavy bag striking, partner drills, dynamic stretching, static/isometric stretching, calisthenics, stick fighting, forms and board breaking. The fighting techniques are designed to address real assault situations, and the physical conditioning portion was developed over years of research and in consultation with various physical therapists.

Our atmosphere is challenging, but accomodating. We aren't your "masters," but work together as respectful friends. We will work with you, at your pace, to help you develop good conditioning and self defense skills.

Classes are taught by experienced, skilled instructors who also know First Aid, CPR and AED use. A full First Aid kit and AED are on site.

To get started call, email, or drop by the gym before class (wear clothes that will be comfortable for exercise). You may also want to go through our free public seminar first. It is up to you.

College credit (PE) is available if you sign up through Chemeketa Community College. Look for the "Personal Protection" class listing, PE185PA. Class syllabus.

Cost: We ask for $150 for a three-month training term. Additional family members get half off. Additional discounts and need-based scholarships are available. MMA and ongoing participants need to purchase their own sparring gear. There are no other belt/test fees, membership costs, uniform or gear purchasing requirements. Referrals and returning participants get an additional 10% off.
