TransliterationTranslation: Inside defence — the deflecting hand works from the inside line (between the attacker's arm and the defender's centreline), redirecting the straight punch outward past the face
Overview
The Inside Defence Against Straight Punch is a core Krav Maga defensive technique where the defender uses the palm of the hand to deflect an incoming straight punch from the inside line — the hand moves from the defender's centreline outward, contacting the inside of the attacker's forearm or wrist and redirecting the punch past the face. [1] The critical principle that separates the Inside Defence from traditional martial arts blocking is SIMULTANEITY: the deflecting hand redirects the punch while the opposite hand delivers a counter-strike to the attacker's face at the same instant — the defender does not block first and then counter, but performs both actions in a single moment. [1],[2] This simultaneous defence-and-attack principle is the defining characteristic of Krav Maga and reflects its development as a military combatives system where the first priority is immediate counter-attack rather than sustained defence. [1],[2] The Inside Defence is the first technique taught in Krav Maga for defending against straight punches (the most common street attack) and is practised at every training session from white belt through expert levels. [1] Imi Lichtenfeld designed the technique to be as simple as possible: the deflecting hand performs a natural sweeping motion outward (similar to brushing a fly off your face), requiring no special skill or training to execute at a basic level. [1],[2] At advanced levels, the Inside Defence is refined to include precise body movement (stepping offline at 15-30°), weight transfer into the counter-strike, and immediate follow-up combinations. [1] Yaron Lichtenstein (9th Dan) documented the technique in The Book of Krav-Maga: The Bible as the foundational defence against the most common unarmed attack. [1]

History & Origin
The Inside Defence was developed by Imi Lichtenfeld (1910-1998) as part of the foundational Krav Maga curriculum, first for the pre-state Israeli paramilitary (Haganah) and later for the Israel Defence Forces (IDF) after Israeli independence in 1948. [1],[2] Lichtenfeld, who had practical experience defending against anti-Semitic attacks in 1930s Bratislava, designed the Inside Defence to be the simplest possible response to the most common attack (a straight punch to the face). [2] The simultaneous defence-and-attack principle was a deliberate departure from traditional martial arts (where students typically learn to block first, then counter in a separate movement) — Lichtenfeld recognised that in real combat, a passive defender who only blocks will eventually be overwhelmed, while a defender who attacks simultaneously disrupts the attacker's initiative. [1],[2] Yaron Lichtenstein (9th Dan), one of the highest-ranked Krav Maga practitioners in the world, documented the technique in The Book of Krav-Maga: The Bible (2007), standardising its instruction for international audiences. [1]
Effectiveness
The Inside Defence is effective because it addresses the most common real-world attack (a straight punch or push to the face/chest) with the simplest possible response (a natural sweeping motion with simultaneous counter-strike). [1],[2] The technique has been validated through decades of use by Israeli military and security forces in actual combat and self-defence situations. [2] Its primary advantage over traditional blocking systems is the simultaneous counter-attack: instead of a block-then-counter sequence (which gives the attacker time to recover between the block and the counter), the Inside Defence delivers the counter at the same moment as the deflection, catching the attacker during their maximum commitment. [1] The technique's simplicity means it can be performed under extreme adrenal stress — the sweeping palm motion does not require fine motor control (which degrades under stress), only gross motor movement. [1],[2]

Biomechanical Mechanism
Primary Action — The palm of the defending hand contacts the inside of the attacker's punching arm (forearm or wrist) and sweeps it laterally outward, redirecting the punch's trajectory past the defender's face — simultaneously, the opposite hand fires a straight counter-strike to the attacker's face
Joints Involved — Defending arm: shoulder (abduction to sweep outward), elbow (slight flexion, arm moves as a unit), wrist (neutral, palm open for maximum contact area); Counter-striking arm: shoulder (protraction for the straight punch), elbow (extension), wrist (aligned for impact); Feet (step offline at 15-30° during the defence); Hips (rotation toward the counter-strike for power)
Force Vector — The deflection travels laterally outward (from centreline to the defender's outside), meeting the incoming punch at approximately 45-60° — this angle redirects the punch past the face without stopping it completely (deflection, not blocking). The counter-strike travels straight forward along the attacker's centreline.
Leverage Principle — The deflection exploits a mechanical vulnerability: a straight punch is powerful along its forward vector but weak laterally — a relatively small lateral force applied to the inside of the punching arm can redirect the entire punch off-target. The palm contact surface provides broad coverage, meaning the deflection works even if the timing is slightly early or late (unlike a precise parry that requires exact blade-on-blade contact).
Position & Entry
Against a right straight punch (standard) — As the attacker throws a right straight, the defender's left hand sweeps outward from the centreline, contacting the inside of the attacker's right forearm — simultaneously, the defender's right hand fires a straight punch or palm strike to the attacker's face
Against a jab — Against a faster, lighter jab, the Inside Defence must be quicker — the deflection is smaller and sharper, and the counter-strike fires as a palm strike rather than a full punch
From passive stance — From a non-fighting posture (hands down, body language non-aggressive — typical self-defence starting position), the Inside Defence can be executed as a sudden explosive reaction when the attack is perceived
With body movement — Advanced version: step the lead foot at 15-30° off the punch's line while performing the Inside Defence — this takes the body completely out of the punch's path while the deflection ensures the fist passes harmlessly
Against a push — The Inside Defence works against shoving pushes to the chest as well as punches — the deflecting motion sweeps the pushing hands aside
Variants
Standard Inside Defence — palm deflection outward with simultaneous straight counter
Inside Defence with palm strike — the counter-strike is a palm heel to the nose or chin
Inside Defence with eye strike — the counter targets the eyes (extreme self-defence situation)
Inside Defence with simultaneous knee — deflecting the punch while delivering a simultaneous knee to the groin or body (when the attacker is close)
Inside Defence stepping offline — adding a 15-30° step to take the body completely off the attack line
Inside Defence from seated — adapted for defending while seated (in a car, at a desk, on a bus)

7 videosWhat Instructors Say
The inside defence against straight punch, known in karate as uchi uke (chudan ude uchi uke), is a fundamental defensive technique taught across multiple martial arts disciplines. Fitness Karate Academy and KRMAmartialarts emphasize the traditional karate execution: the defending arm sweeps from the inside outward across the body, with the forearm meeting the incoming strike at eye level, creating a protective frame for the face. The movement travels in a straight line rather than a circular arc, with proper hand positioning ensuring the blocking arm ends in line with the opposite shoulder while maintaining a firm wrist. Krav Maga Worldwide—Fort Lauderdale introduces a practical sparring perspective, noting that while inside defences are theoretically superior due to better counter-striking position, they become unreliable when an opponent is too close, moving quickly, or when beginners struggle to read which hand is attacking. In such scenarios, Krav Maga instructors recommend switching to covering defences—tucking the chin, placing the palm against the forehead, rotating the body, and using the arm as a shield—which function effectively even when executed with the wrong arm. Fighting Arts Lab frames the inside block as a redirection principle using the opponent's momentum rather than stopping force, emphasizing efficiency and protection of the body's centre line. All instructors agree on the importance of wrist firmness, proper stance, and decisive execution.

Low2/10
The Inside Defence itself causes no injury — it is a deflection. However, the simultaneous counter-strike (palm strike to the nose, punch to the jaw, eye strike) can cause significant injury depending on the target and force. The combined defence-and-counter is designed to end the confrontation immediately.

✓The simultaneous counter-strike is NON-NEGOTIABLE — every Inside Defence must include a counter-strike from the opposite hand. If the student deflects without countering, the drill is repeated. This trains the instinct to always counter-attack, never just defend (Lichtenstein, 2007). [1] Begin with slow, controlled partner drills: the attacker throws a slow straight punch, the defender performs the Inside Defence with simultaneous counter (to a pad held by the attacker's free hand). Increase speed progressively over weeks. [1],[2] The deflecting hand uses the PALM, not the forearm — the open palm provides a broader contact surface than the forearm edge, making the deflection more forgiving of timing errors. [1] Body movement (stepping offline) should be added AFTER the hand defence is solid — students who try to move their feet before they can reliably deflect with their hands develop the habit of running from the punch rather than defending against it. [1] Stress inoculation: perform the Inside Defence drill under physical exhaustion (after sprints, burpees), with surprise attacks (the defender closes their eyes, the instructor attacks at random intervals), and with multiple attackers (deflecting one attacker while being aware of others). [1],[2] Train in street clothes — real attacks do not happen in training gear. The Inside Defence must work while wearing a jacket, carrying a bag, or standing in a confined space. [1] The attacker should progressively increase the realism of their attacks: slow straight → fast straight → committed straight with follow-up combination → surprise attack from conversation distance. [1]
Common Mistakes
!Deflecting without counter-striking — this is the cardinal error in Krav Maga defence; a block without a counter gives the attacker a free second attack. ALWAYS counter simultaneously.
!Deflecting too early — sweeping the hand out before the punch has committed allows the attacker to redirect or feint; wait until the punch is committed before deflecting
!Deflecting too far — sweeping the hand far to the outside opens the centreline for the attacker's other hand; the deflection needs only 4-6 inches of lateral displacement to redirect the punch past the face
!Using the forearm instead of the palm — the forearm provides a narrow contact surface that requires precise timing; the open palm provides a broad surface that is more forgiving
!Not stepping offline — while the hand defence alone can redirect the punch, adding a 15-30° step takes the entire body off the attack line, providing double insurance
!Freezing after the defence — the Inside Defence is the OPENING move, not the entire response; after the deflection and counter-strike, the defender must continue with additional combatives (punches, knees, elbows) until the threat is neutralised

Frequently Asked Questions
Why should I maintain distance when using inside defense against a straight punch?
According to Krav Maga Worldwide, maintaining greater distance forces your opponent to take a big step forward, making the punch easier to see coming. Inside defenses also provide better counter-striking ability, but only work effectively at range; if your opponent gets too close, you won't have time to react.
What's the most common mistake beginners make with covering defenses?
Krav Maga Worldwide instructors emphasize that beginners often hold their hands too far away from their head, causing the punch to bounce back into their own face, or position them too low to protect against the strike. Your palm and arm must be glued close to your head or forehead to create an effective shield.
Do I need to identify which hand is punching to defend against a straight punch?
With covering defenses, you don't necessarily need to read which hand is attacking—even if you use the wrong arm, the defense will often still work because the cover creates a protective shield that can deflect punches regardless of which side they come from.
How should the inside block come around when executing uchi uke?
According to Seamus O'Dowd, the inside block must always come around to the front—never come straight in from the side. The pulling hand comes from the hip, and the blocking arm circles around while your weight stays forward, not pulled back.
