What Is Worm Guard?
Worm guard, developed by Keenan Cornelius, uses the opponent's lapel (gi jacket hem) threaded under the leg to create an extreme control position. The lapel wrap locks their arm and hip in a mechanical disadvantage that is extremely difficult to escape and creates powerful off-balancing force.
Establishing Worm Guard
From De La Riva guard or open guard: reach under your own leg and grab the opponent's lapel, thread it under your leg, and pass it to your other hand (now behind their knee). The lapel wraps around their leg and controls their arm through the jacket.
Entry Requirements
- Start from DLR or a collar-sleeve grip position
- The lapel must pass completely under your thigh
- Control the lapel tightly — slack creates escape routes
- Pair with a collar grip to complete the control system
Off-Balancing from Worm Guard
With the lapel and collar grip established, extend your legs to create forward-diagonal force. The opponent cannot base forward because the lapel restricts their arm. This creates a unique off-balance angle that most passers cannot counter.
Sweeps from Worm Guard
The back roll sweep: when they base backward, use both feet to elevate and roll them overhead. The lapel prevents their arm from posting. The diagonol sweep: elevate one side while pulling the other direction with the collar grip.
Back Take from Worm Guard
When the sweep is partially resisted, use the control to roll to the side and take the back. The lapel maintains an arm trap during the transition, making back retention easier than most other back take methods.

How do I prevent my opponent from passing my legs when I'm in worm guard?
Maintaining tight lapel control is crucial to prevent passes. Constantly adjust your grips and use your free leg to block hip escapes and maintain distance. If they try to stack you, use your lapel grip to pull them forward and create space.
What are the main sweep options from worm guard, and when should I use them?
Common sweeps include the 'worm sweep' (lifting their leg and sweeping), the 'technical stand-up sweep' (using the lapel to pull them down as you stand), and the 'spin under' sweep. Use the worm sweep when they are postured up, the technical stand-up when they are trying to pass low, and the spin under when they are trying to pressure forward.
How can I transition to a back take from worm guard effectively?
The most common back take involves using your lapel grip to pull your opponent's head and shoulder down, then stepping your leg over their back as you transition. Alternatively, you can use the lapel to create an opening for a 'sit-up' sweep that leads directly to the back.
Common BJJ Problems & FAQ
To prevent passes, maintain a tight grip on your opponent's lapel with one hand, anchoring it to your hip. Simultaneously, use your other leg's foot to hook their ankle or shin, creating a strong frame that prevents them from squaring their hips and driving forward.
As they posture, use your lapel grip to pull their upper body towards you, creating an angle. Simultaneously, unhook your bottom leg from their ankle and swing it around to secure their hip, driving your shoulder into their back to establish the dominant back control position.
Initiate the sweep when your opponent's weight is forward and they are committed to a forward pressure. To generate power, simultaneously drive your hips upwards and away from them while pulling their lapel towards your opposite hip, creating a lever action that lifts their base and allows you to invert.
