Styles that Contribute to SGMA

Brazilian Jiu-Jitsu
Brazilian
Jiu-Jitsu is a rapidly growing, combat oriented style of martial art,
recently popularised by the UFC (Ultimate Fighting Championships).
Brazilian
Jiu-Jitsu has its roots in 1914, when a Japanese Jiu Jitsu champion by
the name of Mitsuyo Maeda spent time in Brazil demonstrating and
teaching the art. Maeda met an influential businessman named Gastão
Gracie who helped him get established.
In 1917, his son Carlos
Gracie, still a 14 year-old boy, watched a demonstration by Maeda at
the Teatro da Paz and decided to learn jiu-jitsu. Maeda accepted Carlos
as a student, and Carlos went on to become a great exponent of the art
and ultimately, with his younger brother Hélio Gracie became the
founder of Gracie Jiu-Jitsu, modern Brazilian Jiu-Jitsu.
Brazilian
Jiu-Jitsu came to international prominence in the martial arts
community in the 1990s, when Brazilian Jiu-Jitsu expert Royce Gracie
won the first, second and fourth Ultimate Fighting Championships.
Royce fought against often much-larger opponents who were practicing
other styles, including boxing, shoot-fighting, karate, judo, tae kwon
do and wrestling. It has since become a staple art for many MMA
fighters and is largely credited for bringing wide-spread attention to
the importance of ground fighting.
Brazilian Jiu-Jitsu (BJJ) is
widely recognised as one of the world’s most effective ground fighting
(grappling) arts. SGMA utilises BJJ techniques, teaching students how
to safely take down an opponent, and apply joint manipulations and
chokes to gain control of the situation.
Karate

Karate is a martial art developed from Chinese kenpo (in particular, Southern Chinese kung fu) and indigenous fighting methods from the Ryukyu Islands. It is primarily a striking art, featuring punching, kicking, knee and elbow strikes, and open-handed techniques, but grappling, joint manipulations, locks, restraints, throws, and vital point striking are also taught, depending on the style.
Modern karate training is commonly divided into kihon (basics or fundamentals), kata (forms), and kumite (sparring). Another popular division is between art, sport, and self-defense training.
Aikido

Aikido is a Japanese martial art developed by Morihei Ueshiba as a synthesis of his martial studies, philosophy, and religious beliefs. Aikido is often translated as "the Way of unifying (with) life energy" or as "the Way of harmonious spirit." Ueshiba's goal was to create an art that practitioners could use to defend themselves while also protecting their attacker from injury.
Aikido techniques are normally performed by "blending" with the motion of the attacker, rather than directly opposing the attack. The aikidoka (aikido practitioner) redirects the attacker's momentum, using minimum effort, with various types of throws or joint locks. Aikido can be categorized under the general umbrella of grappling arts.
Judo

Judo, meaning "gentle way", is a modern Japanese martial art (gendai budo) and combat sport, that originated in Japan in the late nineteenth century. Its most prominent feature is its competitive element, where the object is to either throw one's opponent to the ground, immobilize or otherwise subdue one's opponent with a grappling maneuver, or force an opponent to submit by joint locking the elbow or by applying a choke. Strikes and thrusts (by hands and feet) - as well as weapons defenses - are a part of judo, but only in pre-arranged forms (kata) and are not allowed in judo competition or free practice (randori).
