Over-Under

The default clinch

The over-under is the most common clinch position in MMA. Each fighter has one underhook (an arm under the opponent's arm, hand on the upper back) and one overhook (an arm over the opponent's arm, hand on the shoulder or upper arm). The position is mirrored — if you have an underhook on the left side, the opponent has an underhook on the right side, and so on.

Because both fighters have one underhook each, the over-under is a neutral position. It can break to either fighter's advantage depending on who wins the immediate scramble: attacking a takedown, pummeling to double underhooks, striking from the position, or disengaging.

Mechanics

• Underhook: arm runs under the opponent's arm. The hand is on the upper back, the forearm is along the opponent's rib cage, and the elbow is high to prevent the opponent from pummeling out.
• Overhook: arm runs over the opponent's arm. The hand can grip the shoulder, the back of the elbow, or stay on the upper back. The overhook is generally less dominant than the underhook because it can be turned into a head-and-arm choke or an Americana.
• Head position: head into the opponent's chest or shoulder. Heads turned outward expose the neck.
• Hip position: hips engaged with the opponent's hips, weight distributed forward.
• Stance: low and wide, ready to pummel for the second underhook or to defend an attack.

Options from over-under

• Pummel to double underhooks: swim the overhook arm inside to convert the position to double underhooks. The dominant clinch position.
• Takedown attempt: drop levels through the underhook and shoot for a knee tap, outside trip, or body lock.
• Knee strikes: short knees to the body or thighs from the close range. Used by Anderson Silva and Wanderlei Silva.
• Dirty boxing: short hook punches with the overhook arm while controlling with the underhook. Randy Couture pioneered this in MMA.
• Throws: judo and wrestling throws like the harai goshi (outside hip throw) or the uchi mata (inside thigh throw) from the over-under position.
• Break and reset: a frame on the chest or a step backward to disengage and return to striking range.

Pummeling

Pummeling is the constant work of trying to convert the overhook arm into an underhook. The mechanics:

• Swim: the overhook arm dips down and inside, sliding under the opponent's arm to establish a new underhook.
• Counter-pummel: the opponent simultaneously tries to swim their overhook inside. Both fighters fight for the inside position at the same time.
• Result: whoever wins the swim ends with double underhooks; whoever loses ends with double overhooks. Pummeling exchanges in MMA last only a few seconds before resolution.

Common errors

• Hand low on the underhook: the underhook hand needs to be high on the upper back to control the opponent's posture. A low underhook (around the rib cage) gives the opponent space to hip out and circle.
• Elbow low on the underhook: a low underhook elbow lets the opponent pummel inside easily. Keep the elbow high and tight.
• Head outside the opponent's shoulder: exposes the neck to a guillotine or a collar tie.
• Static clinch: holding the position without working an attack gives the referee reason to break for inactivity. Always pummel, knee, or attempt a takedown.

Defending the over-under

• Pummel for double unders: the fundamental defense to losing the position is winning the pummel. Constant swimming for the inside position.
• Frame and circle: post a forearm across the opponent's neck or chest to create space, then circle out.
• Disengage: step backward while shoving the opponent away by the chest or shoulders.
• Knee strike on entry: a knee to the body as the opponent enters the clinch can disrupt the position before it's fully established.

Exemplified by

• Randy Couture — pioneered dirty boxing from the over-under, finishing Vitor Belfort and Chuck Liddell with the position.
• Anderson Silva — used the over-under as a setup for knee strikes in the Thai plum, with the underhook controlling posture before transitioning to the double collar tie.
• Wanderlei Silva — Chute Boxe-style knee strikes and dirty boxing from the over-under in PRIDE.
• Daniel Cormier — heavy-pressure over-under work that wore down opponents in five-round heavyweight and light heavyweight title fights.
• Henry Cejudo — used the over-under as a wrestling chain entry, converting to body lock and takedown.

Drills

• Pummel drill: 3 × 3 min rounds of constant pummeling, with both partners working for double underhooks.
• Over-under to takedown chain: from the position, drill the knee tap, outside trip, and body-lock conversion.
• Dirty boxing pad work: pad holder simulates an over-under clinch; you fire short hooks and uppercuts with the overhook hand while the underhook controls.
• Live clinch sparring: 3 × 3 min of clinch-only sparring starting from over-under. No takedowns or strikes initially; build up to full integration.
• Knee strike from clinch: pad holder simulates the position; you fire short knees to the body and inside thigh, focusing on hip drive.
