Single Leg Takedown

Quick Introduction​

The single leg is the highest-percentage takedown in BJJ competition. It works because you only need to control one leg, you can attack it from multiple angles, and it chains naturally from failed double legs, arm drags, and snap downs. Unlike the double leg, which requires you to penetrate between the opponent's legs, the single leg attacks from the outside — keeping you safer from guillotines and sprawls.

Every serious competitor needs a single leg. It rewards timing over raw athleticism, offers three distinct finishes depending on your position, and is the backbone of chained wrestling sequences at every level.

Position Overview​

From: Grip Fighting, open stance, failed double leg, arm drag, snap down | Leads to: Side Control, top Guard, opponent in Turtle

Run the Pipe Finish (Primary)​

The classic single leg finish. You drive forward with the captured leg between yours, running your opponent backward until they fall.

  1. Secure the single leg — both arms wrapped around the thigh, head on the outside
  2. Pull the captured leg tight between your legs (their foot between your feet)
  3. Posture up — don't stay bent over. Chest up, hips underneath you
  4. Drive forward with short, choppy steps (like running through them)
  5. Keep constant forward pressure — they're hopping backward on one leg
  6. As they fall, follow them to the mat and establish top position

Key detail: Short, choppy steps with relentless forward drive. Don't take big steps — that gives them time to hop and recover balance. Think of running them through a pipe. Your forehead drives into their shoulder or chest the entire time.

Dump/Trip Finish (High Leg)​

When the opponent manages to stay upright or starts hopping effectively, lift the leg high and take their base out from the other side.

  1. Secure the single leg with both arms wrapped around the thigh
  2. Lift the captured leg high — up to your chest or higher
  3. Step your outside foot behind their supporting leg (the one still on the mat)
  4. Pull the captured leg across your body while tripping their base leg
  5. They fall sideways over your blocking leg
  6. Follow to top position — typically land in side control

Key detail: The higher you lift the captured leg, the more unstable they become on one foot. Your outside leg blocking behind their base leg is what makes this work — without it, they just hop and recover.

Inside Trip Finish (Ouchi Gari)​

A judo-influenced finish that works when you have inside head position or when the opponent is defending the run-the-pipe by squaring their hips.

  1. Secure the single leg — head on the inside (between you and the captured leg)
  2. Step your inside foot behind their supporting leg, hooking it at the ankle or calf
  3. Drive your chest and shoulder into their chest — forward and slightly downward
  4. Reap their supporting leg backward with your hooking foot
  5. They fall backward as their base is swept out and your weight drives them down
  6. Follow through to top position — side control or mount

Key detail: This finish requires commitment. Your chest must drive into them while your foot reaps. Half-hearted attempts let them base out and counter. The reaping leg sweeps through, not just touches — think pendulum.

Entries and Setups​

The single leg rarely works as a cold shot. These setups create the opening.

Snap Down to Single Leg: Pull their head down with a collar tie, forcing them to post their hands on the mat. As they posture back up, their weight shifts — shoot the single leg on the side they're light.

Arm Drag to Single Leg: From a 2-on-1 or sleeve grip, drag their arm across your body. This clears the path to their lead leg and turns their shoulders, killing their ability to sprawl.

2-on-1 to Single Leg: Control one arm with both hands. Push-pull to create movement, then release and shoot on the controlled side. They can't frame or post with a dead arm.

Collar Drag to Single Leg: Pull their collar sharply across your body. Their momentum carries them forward and sideways — attack the leg on the side they step toward.

From Failed Double Leg: When a double leg gets sprawled or stuffed, switch to the nearest leg. This is the most natural chain in wrestling — the double-to-single transition is automatic at higher levels.

Core Principles​

  1. Level change creates the takedown — Your shot lives or dies with the initial drop. Explosive hips-down, knees-bent level change is the engine that powers everything.
  2. Penetration must be deep — Your hips need to be close to their hips. A shallow shot with arms reaching means an easy sprawl and front headlock for them.
  3. Head position determines the finish — Outside head: run the pipe (safest). Inside head: trip or dump (more finishes available, more guillotine risk).
  4. Stay tight to the leg — Once you have the leg, it stays glued to your chest. Space between your body and their thigh means they can pummel free or kick out.
  5. Chain attacks — A single finish rarely works at higher levels. Be ready to switch between run the pipe, dump, and inside trip based on their defense. If they sprawl hard, switch to an ankle pick or duck under.

Common Mistakes​

MistakeFix
Reaching for the leg without level changeDrop your hips first, then step and grab. The level change creates the shot.
Shallow penetration stepStep deep — your lead foot should land past their lead foot. Hips close to hips.
Head down, eyes on the groundHead up, drive your forehead into their hip or shoulder. Head down = guillotine.
Stopping after grabbing the legThe grab is just the start. Immediately transition to your finish — don't hold and rest.
Standing straight up with the legPosture up but keep forward pressure. Standing tall and static lets them balance and counter.
Not chaining to other attacksIf run the pipe stalls, switch to dump. If dump stalls, switch to inside trip. Keep moving.

Next Steps​

  1. Double Leg - Chain naturally from single leg; the single-to-double and double-to-single sequence is fundamental
  2. Takedowns Overview - Strategic context for all takedown options
  3. Side Control - Consolidate position after landing the takedown
  • Grip Fighting - Essential setup for creating single leg opportunities
  • Guillotine - The primary risk when head position is wrong; know this to defend it
  • Turtle - Common opponent response when they're taken down but not flattened
  • Guard System - Where you may land if the finish is contested
