Reaping in BJJ is when a competitor’s leg crosses their opponent’s knee from the outside, applying inward pressure on the knee joint. This is considered dangerous because it can lead to serious knee injuries, which is why it’s illegal in most gi and lower-belt no-gi competitions.
Why Is Reaping Illegal?
Reaping puts the knee in a vulnerable position, increasing the risk of ligament damage. Many tournaments, like those under IBJJF rules, strictly prohibit it at white, blue, and purple belt levels to protect competitors. However, in advanced no-gi divisions and certain rule sets (like ADCC), leg reaping is allowed, often in combination with heel hooks.
How to Avoid Reaping
- Keep your outside leg away from your opponent’s knee line when attacking leg locks.
- If playing a leg entanglement game, be aware of your foot placement to avoid accidental reaping.
- Understand your gym or competition rules to ensure you’re training safely.
Where is Reaping Currently Not Legal?
Reaping is currently not legal under the following organizations and rule sets:
- IBJJF (International Brazilian Jiu-Jitsu Federation) – Illegal in gi and lower-belt no-gi divisions (white, blue, and purple belts). Allowed for brown and black belt no-gi with restrictions.
- JJWL (Jiu-Jitsu World League) – Follows IBJJF rules, making reaping illegal in most divisions.
- SJJIF (Sport Jiu-Jitsu International Federation) – Prohibits reaping in standard divisions.
- UAEJJF (United Arab Emirates Jiu-Jitsu Federation) – Follows IBJJF guidelines, so reaping is illegal in most cases.
Reaping is legal in some organizations like ADCC and certain invitational events, especially in advanced no-gi divisions.
