Feedback and testimonials shared by our students regarding their training experiences.
Charles Grayson
Rating: 5/5 Stars "After being introduced to Ninja Bob by another student, I had the privilege of training with Bobby Calvert for several years. I was continually amazed by his exceptional skills, depth of knowledge, and dedication. From completing numerous indoor and outdoor classes to attending multiple Black Scorpion Ninjutsu Society training camps, every session truly pushed my limits. Bobby is a phenomenal instructor, martial artist, and mentor!"
Shannon McKinney
Rating: 5/5 Stars "Ninja Bob’s park sessions are top-tier. Training outdoors in the elements tests your grit and forces you to focus on practical application in real-world settings. The Black Scorpion Ninjutsu Society outdoor workouts are challenging, highly functional, and a great way to train."
Charles Porter
Rating: 5/5 Stars "Training outdoors in the park with Bobby Calvert adds a whole new level of realism to martial arts. Ninja Bob teaches how to adapt your footwork and self-defense techniques to uneven ground and real-world environments. The open-air sessions at the park are tough, refreshing, and entirely practical."
Brandon Williams
Rating: 5/5 Stars "I started training with Bobby Calvert at 18. Through years of indoor and outdoor classes, Ninja Bob's expert coaching helped me earn my 3rd-degree black belt, win tournament trophies, and compete in full-contact fights. I've also proudly served as an assistant instructor. A world-class mentor and friend!"
Amy Parks
Rating: 5/5 Stars "I first met Bobby Calvert at the Margaret Maddox Family YMCA, and working with Ninja Bob has completely transformed my fitness and self-defense journey. Through a combination of fitness boxing and weight training across the YMCA and Planet Fitness in Madison, he has helped me get in shape, lose weight, and build real confidence. An exceptional instructor!"

Honoring the Past, Uniting the Present: Everyone Is Welcome!
Traditional Martial Arts were born outdoors, not on smooth vinyl mats. Train natural movement, silent footwork, spatial awareness, and practical striking across the rocks, dirt, and timber of Middle Tennessee.
Our training is grounded in the traditional roots of Bujinkan and enriched by the modern, practical approach of To-Shin Do.
