The Reap

What This Is

The reap is a ground-level leg entanglement entry performed from a seated or guard position. The guard player threads their inside leg across and behind the opponent’s leg — the attacking foot passes behind the opponent’s near leg, creating an immediate entanglement geometry that provides access to ashi garami, outside ashi garami, or cross ashi depending on which direction the opponent moves and which configuration the bottom player commits to.

The reap is distinct from the false reap — the reap threads the leg to the inside of the opponent’s leg (between the legs), while the false reap threads to the outside. This geometry determines which submissions are most directly accessible. The reap provides the most direct path to cross ashi / inside heel hook because the leg position naturally creates inside access.

The position itself carries no elevated injury risk. The submissions it leads to — particularly the inside heel hook from cross ashi — are elevated risk. Practitioners entering the reap should understand the downstream risk profile before drilling entries with speed or resistance.

The Invariable in Action

The reap works because threading the leg disrupts the opponent’s base. The moment the inside leg crosses behind the opponent’s leg, their weight distribution shifts — they cannot easily step away or post on that side without stepping across or over the entering leg. This brief destabilisation is the window for entry. The leg entanglement captures the position created by the disruption.

The reap entry requires body connection before the leg can be threaded. Attempting to insert the leg from distance — without first establishing hip-to-hip or shin-to-shin contact — allows the opponent to simply step back and remove the leg from danger. The connection constrains their movement; the thread captures it.

The direction of the reap and the attacker’s subsequent hip positioning determine which submission family is accessible. Inside leg position with the hip driving through creates cross ashi access. Holding a wider position with the hip back creates outside ashi access. The hip movement in the first moment after threading sets the submission trajectory.

Entering This Position

From Seated Guard

The most common entry. The bottom player sits with one leg extended toward the standing opponent. As the opponent squares up or steps forward, the bottom player hip escapes to create the angle, plants the outside foot on the mat for base, and threads the inside leg across the opponent’s near leg from the inside. The foot passes behind the opponent’s knee — the leg is now in the reap configuration.

From Z-Guard / Knee Shield

From knee shield, when the opponent is attempting to pass over the shield, the bottom player can drop the shield and thread the inside leg into the reap. This is a defensive-to-offensive conversion: the knee shield was preventing the pass; the reap converts that defensive position into a leg entanglement entry.

From Reverse De la Riva

Reverse DLR naturally positions the bottom player’s leg behind the opponent’s near leg. Converting from reverse DLR to the reap is a positional adjustment rather than a complete reconfiguration — the leg is already in a partial reap position.

From This Position

The reap is a transitional entry, not a holding position. The next step is always a commitment to a specific entanglement.

Common Errors

• Threading from distance: attempting to insert the leg without first establishing contact. The opponent steps away and the entry fails before it begins.
• No commitment after threading: pausing in the reap position without committing to an entanglement. The position is unstable — the opponent can extract their leg if the bottom player does not immediately drive to a specific entanglement.
• Confusing the reap with the false reap: threading to the wrong side of the opponent’s leg. The reap goes to the inside; the false reap to the outside. The downstream submissions are different — committing to the wrong thread leads to an unfamiliar position.

Drilling Notes

Entry + commitment drilling: drill the reap entry as a two-part sequence — (1) thread and (2) immediately commit to ashi garami. The second part should be automatic. Practise the full sequence, not the entry alone.

Response drilling: have the partner step in three different ways (forward, back, lateral) and practise selecting the appropriate commitment based on the response. The reap sets up different entanglements depending on the opponent’s movement — training the decision is as important as training the entry.

Slow threading: practise the leg thread in isolation at slow speed before adding any commitment. The leg must travel cleanly behind the opponent’s knee — developing kinesthetic awareness of the correct path prevents threading errors under resistance.

Ability Level Guidance

Foundations

Understand what the reap is and what it leads to. Know the difference between inside (reap) and outside (false reap) threading. Do not study this position without also understanding the safety profile of the submissions it creates access to.

Developing

Build the reap to ashi garami entry as a single fluid movement. Once that sequence is consistent, add the outside ashi alternative. Study how the opponent’s response determines the correct commitment.

Proficient

Add the cross ashi entry from the reap. At this level the reap becomes a three-way threat — ashi, outside ashi, or cross ashi — based on reading the opponent’s reaction at the moment of threading.

Ruleset Context

The reap itself — the entry position — is legal in all formats. The submissions it provides access to carry their own ruleset restrictions. Inside heel hooks (via cross ashi) are restricted in IBJJF at lower belt levels. Outside heel hooks carry similar restrictions. Know the ruleset before committing to a specific entanglement.
