Sweep Single Leg

SubFamily

スイープシングル(Suīpu Shinguru)

Transliteration

Translation: sweep single (katakana)

Overview

The Sweep Single Leg subfamily attacks the opponent's lead leg with a sweeping motion at knee height, combining a reach for the leg with a lateral sweeping force to collapse the opponent's base. [1] Unlike direct-drive single legs that attack in a straight line, the sweep single uses an arcing, crescent-shaped attack path that approaches the leg from the outside and sweeps it inward. [1],[2] Sweep singles include knee taps and standard sweep singles, both of which use the sweeping mechanic to off-balance the opponent. [2] The lateral force vector makes sweep singles effective from angles where direct shots would be telegraphed. [2],[3]

Training Notes

Attack laterally across the opponent's body, sweeping the lead leg at knee height
Use the opposite hand on a collar tie or post to control their upper body direction
The sweep single is faster than a standard single because you don't need a deep penetration step
Combine the sweeping reach with a lateral push to off-balance before contact
Keep your level low during the sweep to stay under their center of gravity
The sweep single works especially well against an opponent in an open (opposite lead) stance

Common Mistakes

!Reaching for the leg without controlling the upper body first — easy to stuff
!Sweeping too high (mid-thigh) or too low (ankle) — knee height is the sweet spot
!Staying upright during the sweep, telegraphing the attack and losing leverage
!Not driving laterally as you sweep, relying only on the arm pull
!Targeting the rear leg when the front leg is closer and more vulnerable to the sweep
!Over-reaching and crossing your feet, destroying your own base

Frequently Asked Questions

How do I set up the sweep single leg with an underhook?

Coach Brian from TeachMeGrappling recommends getting an underhook by moving your elbow outside, then pulling to get your partner's leg to step forward and square up their stance defensively.

What's the most important detail to keep the sweep working when my opponent has a strong base?

According to BIG OSS Jiu-Jitsu Channel, keeping your heel pointed correctly and maintaining hip elevation behind the opponent's knee is critical—if your foot becomes loose, your hip will drop and the sweep fails. Pinching your knees tight and keeping your elbows tight on your thighs helps maintain the connection.

What do I do if my opponent bounces on their far leg when I attempt the sweep?

BIG OSS Jiu-Jitsu Channel emphasizes not letting go when they bounce—keep your hands on the knee, take their far leg out, and bring them back with your bottom foot to elevate your hip and complete the sweep.
