Brazilian Jiu-Jitsu (BJJ) is a dynamic martial art. It emphasizes ground fighting, submission grappling, and leverage-based control over brute strength. With its rapid growth in popularity across the globe, practitioners are constantly exploring the depth of BJJ techniques. BJJ has achieved tremendous fame both in training in BJJ Gi or No-Gi. But amidst the countless BJJ moves, it is crucial to understand what’s legal and illegal. It is more important when competing under the International Brazilian Jiu-Jitsu Federation (IBJJF) rule set.

The IBJJF has established a detailed list of rules. These rules ensure fairness, athlete safety and standardized competition formats. Knowing which BJJ techniques are prohibited is not just about avoiding disqualification. It is more about respecting your training partners and avoiding serious injuries.

Understanding the IBJJF Rule Set

Before exploring the list of banned techniques, it is important to understand how IBJJF determines legality based on belt ranks and age divisions. Certain techniques that are illegal for white belts may be legal for blue belts and above. Similarly, rules differ for juvenile versus adult competitors. Moreover, the rules vary slightly between Gi BJJ and No-Gi BJJ formats.

• Gi BJJ involves wearing a traditional kimono. Thus, allowing grips on sleeves, lapels, and pants.
• No-Gi BJJ does not involve the Gi. Hence, it focuses more on body control, underhooks, overhooks, and speed.

Let’s now explore the Top 10 Banned IBJJF Techniques that every practitioner and competitor must be aware of.

Top 10 Banned IBJJF Techniques (Across Various Divisions)

Following are the techniques that are banned as per IBJJF rule sets:

1- Heel Hooks (In Gi Divisions and Lower Belts)

Heel hooks are among the most dangerous BJJ moves due to the rotational force applied to the knee. Under IBJJF rules, heel hooks are:

• Banned in all Gi divisions, regardless of belt level.
• Illegal for all belts below brown belt in No-Gi.
• Allowed in adult No-Gi brown and black belt divisions (introduced only recently with rule changes).

Why it’s banned: The torque on the knee joint can cause severe ligament damage almost instantly, even without pain as a warning signal.

2- Knee Reaping (Outside of Legal Situations)

Knee reaping involves crossing your outside leg across your opponent’s hip during leg entanglements. It’s illegal in most Gi and No-Gi divisions unless certain criteria are met (e.g., brown/black belt No-Gi with heel hooks allowed).

Why it’s banned: The position places excessive pressure on the opponent’s knee and can lead to ACL or MCL injuries.

3- Neck Cranks

Neck cranks apply force to the cervical spine, often without a choke, by pulling or twisting the head. IBJJF prohibits neck cranks across all belt levels and age groups.

Why it’s banned: High risk of spinal injury and little room for safe tapping.

4- Slamming from Guard or Submission

Slamming to escape submissions or lifts from guard is illegal in all divisions.

Why it’s banned: Can cause head, neck, and spine trauma. Especially when trying to counter submissions like triangle chokes or armbars.

5- Bicep and Calf Slicers (Lower Belt Levels)

Bicep slicers apply pressure to the bicep with the shin or forearm. Calf slicers do the same to the calf muscles.

IBJJF Legality:

• Illegal for white and blue belts.
• Allowed at brown and black belt levels.

Why it’s banned: These BJJ techniques can crush nerves and muscles. Thus, causing long-term damage.

6- Twisting Toe Holds (Lower Belts)

Toe holds are foot locks that twist the ankle. They are:

• Illegal for white and blue belts.
• Allowed for brown and black belts in Gi and No-Gi.

Why it’s banned: The twisting motion can injure the ankle and ligaments quickly, often before the practitioner feels any pain.

7- Spinal Locks Without Choke

Spinal locks such as the can opener (pulling the head toward the chest) are banned when not combined with a choke.

Why it’s banned: Can hyperextend the neck and cause spinal damage.

8- Wrist Locks (For Juvenile and White Belts)

Wrist locks, while effective, are considered dangerous for those still developing basic control.

• Banned for white belts and all juvenile categories.
• Legal for blue belt adults and above.

Why it’s banned: Smaller joints like the wrist are more susceptible to injury from sudden force.

9- Grabbing Inside the Sleeves or Pant Legs (Gi Only)

While BJJ Gi techniques rely heavily on grips, certain grip placements are illegal. Such as inserting fingers inside sleeves or pant legs is prohibited.

Why it’s banned: Can lead to dislocated fingers or small joint manipulation.

10- Covering the Mouth or Nose (Smothering)

Using your hand to cover your opponent’s nose and mouth to prevent breathing is strictly illegal.

Why it’s banned: It is unsportsmanlike and can lead to panic, suffocation, or worse in extreme cases.

Legal Techniques in BJJ Competitions

Understanding what's legal in BJJ is just as important. Here’s a quick breakdown of popular legal BJJ techniques commonly seen in competition across all belt levels:

• Closed guard, open guard, and guard retention strategies
• Sweeps from guard
• Submissions like armbars, triangles, rear naked chokes, and kimuras (depending on belt rank)
• Takedowns such as single-leg, double-leg, and hip throws
• Mount, side control, back control, and other dominant positions
• Always refer to the IBJJF rulebook to stay updated on what is allowed at your specific rank and division.

Why Knowing Legal vs. Illegal BJJ Moves Matters

It does not matter whether you are a competitor or a recreational grappler. Understanding what BJJ techniques are legal or banned is essential for:

• Safety: Avoiding techniques that can lead to injuries for you or your training partners.
• Competition Readiness: Preventing disqualification due to ignorance of rules.
• Progression: Training correctly at each belt level to master techniques appropriate for your skill set.

Respecting the Sport: Upholding the values of Brazilian Jiu-Jitsu. As BJJ emphasizes control, discipline, and respect.
