Crotch Ripper

SAFETY: Crotch Ripper targets the Hip flexors, groin muscles, and inner thigh adductors. Risk: Groin strain or muscle tear. Release immediately upon tap.

Position Variants

Lockdown	42%	Groin strain or muscle tear

The Crotch Ripper is a compression-based leg lock submission originating from the 10th Planet Jiu-Jitsu system, specifically designed to be executed from the lockdown position in half guard. This technique applies intense pressure to the opponent’s groin, hip flexors, and inner thigh muscles through a combination of lockdown control and strategic knee positioning. Unlike traditional joint locks that target specific joints, the Crotch Ripper creates a painful compression that forces the opponent to tap due to muscular strain rather than joint damage. The submission is particularly effective in no-gi grappling where the lockdown can be secured without gi grips interfering with leg positioning.

The Crotch Ripper represents the offensive potential of the lockdown system, transforming a traditionally defensive half guard position into a legitimate finishing threat. When combined with the Electric Chair sweep, it creates a powerful dilemma where defending the compression opens the sweep and vice versa. This technique requires excellent flexibility, hip control, and precise timing to execute effectively, making it a hallmark of the 10th Planet methodology’s emphasis on unconventional attacks from bottom positions. The submission’s effectiveness depends entirely on the attacker’s ability to maintain lockdown integrity while creating the correct body angle through underhook control.

Category: Compression Type: Groin Compression Target Area: Hip flexors, groin muscles, and inner thigh adductors Success Rate: 42% (average across variants)

Safety Guide

Injury Risks:

Injury	Severity	Recovery Time
Groin strain or muscle tear	Medium	2-4 weeks with proper rest
Hip flexor strain	Medium	2-3 weeks
Adductor muscle damage	Medium	3-6 weeks depending on severity
Lower back strain from excessive arching	Low	1-2 weeks

Application Speed: SLOW and progressive - 4-6 seconds minimum to allow partner to recognize pressure and tap

Tap Signals:

• Verbal tap (most common due to leg entanglement)
• Physical hand tap on mat or opponent’s body
• Physical foot tap with free leg
• Any distress signal or vocalization

Release Protocol:

1. Immediately release lockdown figure-four grip
2. Remove knee pressure from groin area
3. Straighten attacking leg to remove compression
4. Allow opponent’s leg to naturally extend and decompress
5. Do not suddenly jerk or twist during release

Training Restrictions:

• Never spike or jerk the submission - apply gradually
• Never practice at competition intensity during training
• Always communicate with partner about pressure level
• Stop immediately if partner shows any sign of discomfort
• Avoid practicing on partners with known groin or hip injuries
• Never combine with sudden sweeping motions that could increase injury risk

Variation Details

Crotch Ripper to Electric Chair combination: Set up Crotch Ripper compression, and when opponent defends by grabbing your attacking leg or sprawling hips back, immediately transition to Electric Chair sweep by loading their weight onto your hip and rolling them over. This creates a powerful submission/sweep dilemma. (When to use: When opponent is defensive and attempts to prevent knee pressure by controlling your attacking leg)

Crotch Ripper from quarter guard: If opponent begins to extract their leg from half guard but you maintain partial control (quarter guard), you can still establish lockdown on their ankle and attempt modified Crotch Ripper with different angle. Your knee pressure comes from different vector but still targets groin area. (When to use: When transitioning between half guard and opponent’s attempted pass, creating offensive opportunity from defensive scramble)

Double attack with Twister hook threat: From lockdown with underhook, threaten Crotch Ripper while simultaneously working Twister side control entry by getting your outside leg over opponent’s shoulder. This forces opponent to defend multiple attacks, often leaving one open. (When to use: Against experienced opponents who defend Crotch Ripper well - the double threat creates openings)
