Mason Martinez

I'm Mason Martinez, also known as The Nunchuck Guy (@stoikninja). I'm a fitness instructor and nunchaku enthusiast based in Scottsdale, Arizona. I am a USMC sergeant and former law enforcement officer. My channel is all about real-world strength: calisthenics, bar skills like the muscle-up, nunchaku training, and many other fitness related activities. Expect clear, no-fluff tutorials that break each skill down into the few things that actually matter, so you can train smarter and hit your first rep sooner. My books: Book 1, Nunchaku Freestyle Flows: www.amazon.com/dp/B0HM6P3LB3?tag=ninjamason-norep-20 Book 2, Nunchaku Laws: www.amazon.com /dp/B0HNGCMRB7?tag=ninjamason-norep-20 (As an Amazon Associate I earn from qualifying purchases.)
