What is Ninja?

Our definition of Ninja is simply understanding how to use your body in order to overcome obstacles. Every BODY is unique and every MIND creates new possibilities. As a community, we continually learn from each other and push each other to become more versatile than we were yesterday.

At the end of each month, all NOM qualifiers will be discussed by KNF Instructors and Staff until we have a distinctive winner. That winner will be notified so we can take a picture and present them with their award.

2) How to Become a NOM:

Progression- Must successfully complete half of “KNF Wall Challenges”

Helpfulness- Must show kindness in helping other ninjas during that month

Attendance- Must have participated in 1 KNF class each week of that month

Quiz- Must pass the 15 question written Seminar Quiz about movement.

3) When Can I Begin?

Each instructional class at Keystone Ninja Factory will involve some type of NOM qualification. Participants each have a chart to follow this progress.

Good luck to everyone during their ninja journey.
