Primary Ground Positions:

Side control

In side control, the practitioner pins their opponent to the ground from the side of their body. The dominant grappler lays across the opponent with weight applied to the opponent’s chest. The opponent may be further controlled by pressure on either side of their shoulders and hips from the practitioner’s elbows, shoulders, and knees. A wide variety of submissions are initiated from side control.

Full mount

In the mount position the practitioner sits astride the opponent’s chest, controlling the opponent with their bodyweight and hips. In the strongest form of this position the practitioner works their knees up under into the arm pits to reduce arm movements, limiting their ability to move or counter the submission attempts. Full Mount can be used to apply armlocks or strangles

Back mount

When utilizing the back mount (often known in Brazilian Jiu-Jitsu as the back grab or rear mount), the practitioner attaches to the back of the opponent by wrapping their legs around and hooking the opponent’s thighs with their heels.[21] Simultaneously, the upper body is controlled by wrapping the arms around the chest or neck of the opponent. This position is often used to apply chokeholds, and counters much of the benefit an opponent may have from greater size or strength.

Guard

In the Guard, the practitioner is on their back controlling an opponent with their legs. The practitioner pushes and pulls with the legs or feet to upset the balance and limit the movements of their opponent. This position comes into play often when an opponent manages to place the practitioner upon his or her back and the practitioner seeks the best position possible to launch counter-attacks. This is a very versatile position from which the BJJ practitioner can attempt to sweep (reverse) the opponent, get back to the feet, or apply a variety of joint-locks as well as various chokes.

The three main types of guard are Open, Closed, and Half. In closed guard, the bottom grappler has their legs around the opponent’s trunk and has their ankles closed together to provide control and a barrier to escaping the position. In the open guard, the legs are not hooked together and the bottom grappler uses their legs or feet to push or pull in a more dynamic fashion. In the half guard, one of the top grappler’s legs is being controlled by the bottom grappler’s legs.

Submissions:

The majority of submission holds can be grouped into two broad categories: joint locks and chokes. Joint locks typically involve isolating an opponent’s limb and creating a lever with the body position which will force the joint to move past its normal range of motion. Pressure is increased in a controlled manner and released if the opponent cannot escape the hold and signals defeat by submitting. Opponents can indicate submission verbally or they can tap out (i.e. tap the opponent, the mat several times. Tapping one’s own body is dangerous because the opponent may not be able to tell if his or her opponent is tapping.) A choke hold, disrupting the blood supply to the brain, can cause unconsciousness if the opponent does not submit soon enough.

A less common type of submission hold is a compression lock, where the muscle of an opponent is compressed against a hard, large bone (commonly the shin or wrist), causing significant pain to the opponent. These types of locks are not usually allowed in competition due to the high risk of tearing muscle tissue. This type of lock often also hyper-extends the joint in the opposite direction, pulling it apart.

Chokes and Strangles

Chokes and strangles (commonly referred to as “air chokes” and “blood chokes”) are common forms of submission. In BJJ, the chokes that are used put pressure on the carotid arteries, and may also apply pressure to the nerve baroreceptors in the neck. This kind of choke is very fast acting (if done properly) with victims typically losing consciousness in around 3–5 seconds. In contrast, an air choke (involving constriction of the windpipe) can take up to two minutes, depending on how long the person can hold their breath, and may cause serious damage to the throat.

Joint Locks

While many joint locks are permitted, most competitions ban or restrict some or all joint locks involving the knees, ankles, and spine. The reason for this is that the angles of manipulation required to cause pain are nearly the same as those that would cause serious injury. Joint locks that require a twisting motion of the knee (called twisting knee locks or twisting knee bars, or techniques such as heel hooks, and toe holds) are usually banned in competitions because successfully completing the move nearly always results in permanent damage that requires surgery. Similarly, joint manipulations of the spine are typically barred due to the inherent danger of crushing or mis-aligning cervical vertebrae. Leglocks are allowed in varying degrees depending on skill level, with straight ankle locks being the only leglocks allowed in the beginner division, or white belt level, straight kneebars being allowed in the intermediate division, or blue belt level and toeholds with the pressure applied inwards are allowed in the advanced division (purple, brown, black). Some competitions also ban submissions involving the crushing or compression of muscle tissue.

However, most joint locks involving the wrist, elbow, shoulder or ankle are permitted as there is a great deal more flexibility in those joints and those locks are safe to use under tournament conditions. Also, some fighters practice moves whose sole purpose is to inflict pain upon their opponent, in the hope that they will tap out. This includes driving knuckles into pressure points, holding their opponent’s head in order to tire out the neck (called the “can opener” or kubi-hishigi) and putting body weight on top of the sternum, floating ribs, or similarly sensitive bones. These moves are not true submission moves; they are generally only used as distractions mostly in lower levels of competition. They are avoided or aggressively countered in middle to upper levels of competition.

Grading:

The Brazilian Jiu-Jitsu ranking system awards a practitioner different coloured belts to signify increasing levels of technical knowledge and practical skill. While the system’s structure shares its origins with the judo ranking system and the origins of all coloured belts, it now contains many of its own unique aspects and themes. Some of these differences are relatively minor, such as the division between youth and adult belts and the stripe/degree system. Others are quite distinct and have become synonymous with the art, such as a marked informality in promotional criteria, including as a focus on a competitive demonstration of skill, and a conservative approach to promotion in general. Traditionally, the concept of competitive skill demonstration as a quickened and earned route of promotion holds true. Some schools have placed a green belt for adults between the white and blue belt ranks due to the long periods between advancement. In addition, the use of a grey belt has been instituted for many children’s programs to signal progress between the white and yellow belt rankings. The amount of time it takes to achieve the rank of black belt varies between the individual but the average time frame is between 8 and 10 years  with a consistent training schedule of 3 to 4 times per week.

Uniform:

The Brazilian Jiu-Jitsu practitioner’s uniform is similar to a judogi, but often with tighter cuffs on the pants and jacket. This allows the practitioner to benefit from a closer fit, providing less material for an opponent to manipulate, although there is a significant overlap in the standards that allows for a carefully selected gi to be legal for competition in both styles. Traditionally, to be promoted in Brazilian Jiu-Jitsu the wearing of the gi while training is a requirement. Recently with the growing popularity of “no gi” Brazilian Jiu-Jitsu, the practice of giving out belts to no gi practitioners (e.g., Rolles Gracie awarding Rashad Evans a black belt) has become more common.

The term kimono is sometimes used to describe the outfit, especially in Brazil.
