Overview

The Block family covers defensive techniques that physically stop incoming strikes by interposing a rigid body part — typically the forearm, shin, or elbow — in the path of the attack. [1] Blocks are the most direct form of striking defence, using hard surfaces of the body to meet the incoming strike and prevent it from reaching its target. [1],[2] Blocks are classified by the height and direction they defend — high blocks protect the head, middle blocks protect the torso, low blocks protect the legs, and elbow blocks use the elbow's hard surface to damage the attacker's striking limb. [2],[3]

History & Origin

Blocking techniques are found in every martial arts tradition worldwide, from karate's formal blocking katas to Muay Thai's shin checks. [1] The systematic classification of blocks by height (jodan, chudan, gedan) was formalised in Japanese karate traditions. [2],[3]

Effectiveness

Blocks use the arms, hands, or legs to intercept and absorb incoming strikes, preventing them from reaching the target. [1],[2]

Lineage

Blocking techniques are found in every striking art, from boxing and karate to Muay Thai and taekwondo. [1],[2]

Competition Record

Blocking is the most basic striking defence used in all combat sports competition. [1]

Biomechanical Mechanism

Primary ActionIntercepting an incoming strike using a rigid arm, forearm, or shin structure to absorb or redirect force
Joints InvolvedForearm and elbow (primary blocking surface), shoulder (positioning), core (absorbing residual force)
Force VectorPerpendicular to the incoming strike — meeting the attack at an angle dissipates force across the blocking surface
Defensive MechanicHard blocks absorb impact directly; soft blocks redirect the strike's trajectory away from the target

Position & Entry

From fighting stanceMaintain guard position, raise the forearm or shin to intercept the incoming strike before it reaches the target
As reactive defenceWhen the attack is detected, move the blocking limb into the strike's path to absorb or deflect the force

Training Notes

Blocks absorb incoming strikes on hard defensive surfaces — forearms, shins, and elbows — to prevent them from reaching vulnerable targets (Haislet, Boxing, 1940)
The four main block categories in striking are: high block (overhead), middle block (body-level), low block (leg-level), and forearm/elbow block (close range)
Blocks are the last line of defence — use footwork and evasion first, blocks when those fail
A good block redirects force rather than absorbing it head-on: angle the blocking surface so strikes glide off
In Muay Thai, the shin check (lifting the leg to block a kick with the shin) is the fundamental kick defence
Keep the guard tight during blocks: elbows close to the body, fists at chin level, chin tucked
Block and counter as one unit: the block stops the attack, the counter exploits the opening — never block without an immediate follow-up plan

Common Mistakes

!Blocking with the hands instead of the forearms — forearms provide a harder, wider blocking surface
!Reaching out to block — keep the blocks close to the body; reaching out creates openings
!Blocking every strike when evading would be more efficient — blocks absorb impact; evasion avoids it entirely
!Tensing the entire body during blocks — tense only the blocking limb; the rest stays relaxed for movement
!Dropping the guard after blocking — immediately return to full guard position
!Blocking without countering — every block should flow into a counter-strike
!Looking away while blocking — keep eyes on the opponent to anticipate the next strike

Sub-techniques

Elbow Block

SubFamily

The Elbow Block subfamily covers blocking techniques where the fighter uses the elbow — one of the hardest and most durable bones in the body — to intercept incoming strikes, both defending the target and potentially damaging the attacker's striking limb. [1] The elbow block is a double-purpose defence: it protects the body behind it while presenting a sharp, hard surface that can cut, bruise, or break the attacker's hand or shin upon contact. [1,2] Elbow blocks are used primarily against body hooks, low kicks, and strikes to the midsection. [2,3]

High Block

SubFamily

The High Block subfamily covers blocking techniques that defend the head and upper area by raising the arm or arms above the head to intercept downward or horizontal strikes targeting the head. [1] High blocks are essential for defending against overhead attacks, high kicks, and downward-angled punches. [1,2] This subfamily includes traditional karate-style rising blocks (age uke), cross blocks (both arms crossed overhead), and forearm blocks used in boxing and MMA. [2,3]

Long Guard

SubFamily

The Long Guard subfamily covers the defensive posture where one or both arms are extended forward, creating a barrier at maximum arm's length that disrupts the opponent's attacks before they develop full power. [1] The long guard uses the extended arm to obstruct the opponent's vision, block punches at their origin, and maintain distance through constant hand contact with the opponent's head or shoulders. [1,2] The long guard is distinct from standard blocking because it is proactive — it disrupts attacks before they launch rather than intercepting them in flight. [2,3]

1 genera·1 techniquesExplore

Low Block

SubFamily

The Low Block subfamily covers blocking techniques that defend the lower body — legs, midsection, and groin — by positioning the arms or legs downward to intercept low-targeting attacks. [1] Low blocks are essential for defending against leg kicks, low punches, and kicks targeting the body below the ribs. [1,2] This subfamily includes traditional karate-style downward sweeping blocks (gedan barai) and the Muay Thai shin check, which uses the shin to block incoming leg kicks. [2,3]

2 genera·2 techniquesExplore

Middle Block

SubFamily

The Middle Block subfamily covers blocking techniques that defend the midsection and torso area by positioning the forearm horizontally or diagonally to intercept strikes targeting the body. [1] Middle blocks protect the vital organs of the torso — ribs, solar plexus, liver — from punches, kicks, and knees. [1,2] This subfamily includes inside-to-outside blocks (soto uke), outside-to-inside blocks (uchi uke), and knife-hand blocks (shuto uke), each sweeping the forearm across the body from different starting positions. [2,3]

Notes

Blocking appears in 7,254 passages across our corpus — the most referenced defensive action. In karate, the four fundamental blocks (age-uke, soto-uke, uchi-uke, gedan-barai) are taught before any offensive technique. In boxing, blocks use the gloves and arms to catch punches.

Frequently Asked Questions

How do I practice blocking while keeping my firearm safe?

Lionquest Fitness emphasizes keeping your non-blocking arm away from your gun during block, strike, and draw drills to maintain safety while integrating defensive movement.

When should I transition from blocking to drawing my weapon?

If an attacker continues advancing despite a warning or begins drawing their own weapon and you have no time to issue a verbal challenge, that is when you would transition to drawing and firing.
