Update on "Ground Rules: Simple Physics for the Grappling Arts"

We're excited to share progress on "Ground Rules: Simple Physics for the Grappling Arts", a book that explains introductory physics concepts like force, leverage, torque, friction, and pressure for grapplers. Designed to help BJJ practitioners understand the mechanics of grappling, it breaks down how these principles apply to highly effective positions, submissions, transitions, and strategies. The complete draft, including illustrations, is finished, and we're nearing publication on Amazon. Stay tuned!
