Interested in an LCMS-owned & developed self-defense curriculum that is entirely online? The Great Flip is based on Brazilian jiu-jitsu, a grappling sport (much like wrestling). The Great Flip Curriculum is a non-combative approach to self-defense. The student will not be taught to strike, kick or use aggression or force. Rather, they explore movements in a safe and positive, explicitly Christian environment for a fun, powerful, and empowering experience. See product details for a discount code.
