The Core Concepts of Throwing Techniques
December 30, 2019
The purpose of a successful throwing technique in sambo is to get an opponent to the mat or ground as effectively as possible with control. A sambo grappler can win a match outright by a total victory by throwing his opponent to the mat with control (largely on the back or backside, or if the opponent lands in a bridge) with the thrower remaining standing at the conclusion of the throw.

Juji Gatame: The World’s Most Popular Armlock - April 29, 2019

The Three Building Blocks Of Learning And Training In Judo - April 1, 2019
In any field of study, there has to be some kind of structure so that the contents of that particular area of study can be logically understood, taught and learned, and ultimately passed on to others. This structure or framework must have a firm theoretical and philosophical foundation based on practical application and, just an important, allow for innovation to take place. It must be fixed, yet flexible so that the activity (in this case judo) has room to grow.
How Biomechanical Principles Apply to Judo - March 11, 2019
Judo is based on sound biomechanical principles. The more efficiently a person applies these principles, the more effectively that person will do judo. To do judo well, a person must know not only how to control his own body but also his opponent's. The Japanese phrases, terms, and names—in use since judo's inception and familiar to all judo practitioners—explain much of what judo is and does.
Judo Isn't Gentle - February 18, 2019
Is judo really the "gentle way?" In the popular meaning of the word, judo certainly isn't anything close to being gentle. To paraphrase the great martial arts writer Donn Draeger; "Judo isn't gentle." And while judo isn't gentle in the more common use of the word, it's certainly efficient; and because it's efficient, it's effective
The Donkey - March 7, 2016
I am not, nor have I ever been, the most physically competent martial artist. It takes me inordinately more classes to attain technical proficiency in many areas than it does others. I am tall and fairly agile, but I do not have much muscle mass. And then, over the past few years, two significant medical challenges have crossed my desk. Couple all this with the fact that I am now in my 60s, and a potentially bleak image begins to materialize.
Dukkha Hungry Ghosts - December 28, 2015
As Mai and the crowd watch in frozen horror, the Lexus slowly rolls again until it's on its top; the front-end still nose down into the water. After a moment, only the rear back tires are still above the surface. Then they too slip beneath the bay.

Dukkha: Hungry Ghosts - A Sam Reeves Martial Arts Thriller - October 26, 2015
Prologue from the book: His legless torso swings back and forth between his arms, as he hand-walks along the dim but ornately lit cobblestone path that meanders about the lavish yard through tall bamboo, past large stone Asian lanterns, around half a dozen towering palm trees, and encircles a large pond. Twelve-foot high brick walls border the large yard on three sides.
Political Turmoil in Taekwondo - August 18, 2014
On December 31, 2013, Grandmaster Kyu Hyung Lee, taekwondoist extraordinaire, formally resigned his post as president of the esteemed Kukkiwon after holding the position for a mere matter of months. Quickly replaced by Man Soon Jang, Lee claimed his startling decision was founded on irreconcilable differences between two leading factions; one consisting of officials whose behavior is largely motivated by politics, and a second group of martial artists, spearheaded by Lee, with the purity of taekwondo at heart.
The Heart of Taekwondo - July 7, 2014
When the heart of taekwondo beats, it gives life to the advancement of supreme discipline, the achievement of noble character, and the cultivation of an enlightened worldview. It breaks the bonds that bind us to the Earth and again, as adults, allows us to feel the wind beneath our feet rather than merely around them.
Dukkha Unloaded-A Sam Reeves Martial Arts Thriller - June 26, 2014
A rush of wind sent debris skittering along the empty sidewalks, filthy gutters, and streets long in need of repair. Though few vehicles passed through the darkened skid row intersection of Northwest Third and Couch at three a.m., its lone traffic signal, swaying in the wind, continued to cycle its colors, casting hues off the sides of old buildings and the cracked windshield of a decaying station wagon propped up on four rusted wheels.
A Few Fighting Techniques Found in the Dukkha Series - June 16, 2014
Many kind reviewers for Dukkha: The Suffering, Dukkha: Reverb, and Dukkha: Unloaded have commented on the realistic violence, in particular the fight scenes. This is always nice to hear because I work hard to infuse the scenes with authenticity and truth. After spending 30 years around man's inhumanity to man, first as a Military Policeman in Vietnam and then as a street cop for 25 years in Portland, Oregon, I find many authors' and movie directors' depiction of violence to be sadly lacking or simply off base.
