About the Training at Boca Ju Jutsu

Training at Boca Ju Jutsu… We offer a variety of training methods. Scenario (mock or walk through training), Sparring (practice), and Kumite (competition), to insure proficiency, and maintain a high level of safety.

Differences in the training occur depending on the experience level, and desires or motivations of the student(s) ie. their ranks (Kyu or Dan ranks), their goals (Avoidance ie. bullying or muggings, lifestyle change ie. weight loss, competition or career ie. Corrections, Bouncer, Police), and physical prowess of the students.

Scenario based training is used in every martial art for many reasons. First to ensure safe practice. Second, it allows the instructor (Sensei) to access the health and condition of the students health and physical prowess. Third, it promotes unity of the students, enhancing the empathy for one another. ¬†Safety is paramount…even though Boca Medical Center is nearby. ūüėÄ

All beginners, people with disabilities, youngsters, and Female self defense enthusiasts, Senario instruction is mostly used, but not exclusively.  It insures the highest quality of teaching, maintaining safety, and builds up the confidence level of the practitioner.  Repetitive actions done without the full application, aka practice drills (Uchi Komi or walk through of the particular technique) ensures the quality of the techniques being taught, and the safety of the students.

Classes begin with physical training. Core exercises, calisthenics, and breathing techniques to improve stamina, and focus one’s energy (Ki, or Chi). Forceful breathing techniques (Kiah) are taught when striking (Atemi), kicking (Geri Waza), and throwing (Nage Waza). ¬†Break falls (Ukemi Waza), and rolling techniques (Kaiten Waza) promote self preservation. Body movement (Tai Sabaki, Kata) teach students to avoid or minimize getting hit, kicked, or thrown, as well as entry to various techniques. ¬†Blocking and avoidance of punches and kicks ie. “checking” and or ‚Äútrapping‚ÄĚ is of paramount importance in the Sparring, and Kumite phases of training.

Sparring and Kumite training is widely varied. We make the rules, and thus can control the level of training to insure safety during these activities.

We can Box western style (punching and blocking w the arms or body movement)…or we can add kicks as in Kickboxing, Savate, Taekwondo or Tang Soo Do…add knee and elbow strikes as in Thai Boxing or Kumite…or add throws and Grappling as in MMA, NHB (No Holds Barred), Cage fighting, Pankration, Jeet kune do, Kenpo karate, Shidokan style karate (3 rounds, 1st boxing, 2nd Kickboxing and sweeping, 3rd Top to bottom)… We can practice ground work only, as in Brazilian Jiu Jitsu (Rolling), Judo (Ne Waza), or Wrestling (from floor), or add leg locking as in Sambo …We can Practice Stand up take down techniques, with or without striking or kicking, as in Stand up Brazilian Jiu Jitsu, Judo (Ashi Waza), or Wrestling top to bottom‚Ķ.We can practice fighting and/or defense from an armed opponent, or multiple attackers. This is similar to Street fighting, Dirty boxing judo and Sambo, Systema, Krav Maga, Military Special Forces, Aikido or Hapkido or Samurai Ju Jutsu. Use of weapons and multiple attackers makes this style of Kumite one of the ¬†most challenging to train in. ¬†We desire to practice it all, because you never know what can happen in real life.

About San Yama Bushi Ryu


Shinan Hector Negron

The San Yama Bushi Ryu and San Yama Bushi School of Judo and Ju-Jutsu was formally introduced in 1985 by Shihan Hector Negron. Shihan Negron began his martial arts training in Puerto Rico at the age of 12, studying Kempo Karate. In 1971, at the age of 19, he moved from Puerto Rico to the Bronx, New York.

After visiting a number of schools, he encountered Shinan Antonio Pereira and the Tremont School of Judo and Ju-Jutsu. There he began studying Judo and Ju-Jutsu under the tutelage of Shinan Pereira, while also continuing to train in Karate.

After diligent and dedicated study, he obtained his black belt in Ju-Jutsu and began teaching at the school, soon after becoming head Ju-Jutsu instructor. Soon after, he earned his black belt in Judo and became an active judo competitor. In 1981 he obtained the rank of Kaiden, and became Head Instructor of the Ryu (equivalent to 9th/10th Dan) in Miyama Ryu Ju-Jutsu.

In 1986, Shihan Negron parted from the hombu dojo in the Bronx and founded his own dojo in Mt. Vernon, New York where he began teaching a more expansive version of the combat Ju-Jutsu he learned and taught in the Bronx. He named this new Ryu, San Yama Bushi, meaning “Three Mountain Warrior.” As founder of this new Ryu, the Board of Directors unanimously bestowed upon Shihan Negron the title of Shinan, meaning “Founder.” By 1999, Shinan Negron’s following became such that the need for a new dojo was clearly at hand. Shinan Negron moved his dojo to New Rochelle, New York where members of the Ryu now train in a 6,000 square foot dojo.

Today, Shinan Negron continues to train individuals from every walk of life, from active police officers whose duties place them in peril, to college students looking to maintain physical and mental edge over those they may encounter in hostile situations.
