Arthrokinetics is the study of how the bodily joints function and dysfunction during a fight. Arthrokinetics enhances YOUR unique style regardless of venue, whether sport fighting, civilian self-defense, military close-quarters combat,or law enforcement subject control.

Drawing upon Scott Sonnon’s experience as a Sambo and Catch-Wrestling background, he carefully breaks down how to “create submissions” in grappling styles and mixed martial arts competitions.

Demonstrating volumes of examples, this veritable encyclopedia teaches the science of submission fighting with Scottt Sonnon’s signature attention to meticulous detail. When you use an understanding of Arthrokinetics, you will accelerate your development and shorten the time required to become an innovator of your own personalized strategy of submission fighting.

Meet Scott Sonnon

Proclaimed by Men’s Health magazine as the creator of “The World’s Smartest Workout,” Tand named in Men’s Fitness magazine as “one of the Top 25 Trainers in the World,” and by Belt Magazine as “one of the 7 most influential instructors of this century, Scott Sonnon changed the world’s view of fitness nearly 30 years ago with the creation of TACFIT.

Scott Sonnon was forced into a life of seeking alternative exercise options due to early childhood joint disease and motor challenges. Institutionalized for his learning difficulties in a psychiatric hospital, teachers and doctors advised that he set low-bar realistic expectations on his potential. Through tremendous persistence, he rose to become an adjunct professor of physical education at Penn State University, a US National Team Coach, and a 5-time international martial arts champion.

What’s Different About Arthrokinetics?


Grappling and ground-fighting styles indoctrinate you with a context-specific skill set, based upon the premise that Stimulus A will produce Reaction B.

However, WHEN the subject does not react as “planned” one is forced to improvise and innovate – attributes not directly taught in grappling & ground-fighting, IF AT ALL. Why is it that instructors of styles tell you that you must “create a variation that meets your needs and abilities” and cannot tell you how to do so? What good are they to you without the vocabulary, understanding and systematic education of the CRUCIAL ATTRIBUTES OF ON-SITE IMPROVISATION AND INNOVATION?


The ability to tactically improvise and innovate joint manipulations is PARAMOUNT to both effectiveness AND survivability in subject control. Through Arthrokinetics you reclaim autonomy over your own mastery, for the System is not some “master’s” prefabricated style to be imposed your unique reality.

Arthrokinetics teaches you how to INNOVATE and IMPROVISE on-site tactical control applications… so that you not only maximize your survivability and effectiveness, but also your courtroom defensibility, for it actually provides you with a concrete, physiological Conflict Response Spectrum. As Scott Sonnon says, “Becoming more Response-Able, necessarily increases the ability to respond to all situations.”

“Arthrokinetics is the true map to orient conflict resolution, and YOU are the landscape. It is the bridge between biomechanics and subject control, creating scientific order out of combat’s chaos.”

“Hey Coach, I just wanted to send you a thank you for putting all your teaching out there. I’ve watched the entire Arthrokinetics tape set literally about 30 times. (I watch it while I jump rope every night.) It’s amazing!! It really works. I tapped out a bjj purple belt (with a “knee bar”) and the best thing was that he placed his leg into the position where I could lock it. I didn’t force anything. I now have more mobility (more consistently) than I can remember…. ever… thanks to GTB and WW. The reason I’m writing this is because I spent two years learning tai-chi. Although interesting, it never lived up to my expectations. Some days I could flow and other days it was gone. With your stuff I can flow (almost) at will.”
