Overview
The Slip subfamily covers the defensive technique where the fighter rotates the upper body laterally to move the head off the centreline, allowing a straight punch to pass over the shoulder. [1] Slipping is the most commonly used head movement defence in boxing because it is effective against the most common attacks — jabs and crosses — while keeping the fighter in range for counter-punches. [1],[2] Slips can be executed to the inside (toward the opponent's body) or to the outside (away from the opponent's rear hand), each creating different counter-attacking opportunities and risks. [2],[3]

Biomechanical Mechanism
Primary Action — Moving the head off the centre line to avoid an incoming strike without retreating
Joints Involved — Cervical spine (lateral flexion), knees (level change for bob and weave), hips (rotation for counter position)
Force Vector — Lateral or downward — the head moves just enough to make the strike miss while maintaining counter-striking distance
Counter-attack Advantage — Slipping loads the rear hand or lead hook for an immediate counter — defensive movement becomes offensive positioning
Position & Entry
From fighting stance — Move the head laterally (slip) or vertically (bob-and-weave) to make the incoming strike miss by inches
As counter-setup — Slip the punch and immediately counter — the defensive movement loads the counter strike

✓The slip moves the head laterally off the centreline to avoid a straight punch — you lean to the outside of the punch so it passes over your shoulder (Haislet, Boxing, 1940)
✓Slip by bending the knees and rotating the torso slightly — the head moves 3-4 inches laterally, no more
✓Inside slip goes toward the opponent's body (inside the punch); outside slip goes away from the opponent (outside the punch)
✓The outside slip is generally safer — it takes your head away from the opponent's other hand
✓The inside slip is more offensive — it puts you in position for body shots and hooks, but exposes you to the other hand
✓Slip at the last possible moment — early slips telegraph your defence and allow the opponent to adjust
✓After every slip, immediately return to centre or counter — never stay in the slipped position
Common Mistakes
!Leaning at the waist instead of bending the knees — the slip should lower your level slightly, not just tilt your torso
!Moving the head too far laterally — a 3-4 inch movement is sufficient; more wastes energy and position
!Dropping the hands while slipping — maintain your guard throughout
!Slipping straight backward instead of laterally — that's a pull-back, not a slip; slips are sideways
!Slipping before the punch is thrown — this telegraphs your defence and the opponent adjusts
!Staying in the slipped position — return to centre immediately to avoid the follow-up
!Slipping punches that aren't aimed at you — wasted movement; only slip strikes on target

Inside Slip
GenusThe Inside Slip moves the head to the inside of the incoming punch (toward the opponent's centre), rotating the upper body so the punch passes over the outside shoulder. [1] The inside slip is more aggressive than the outside slip because it moves the defender closer to the opponent, placing them in range for counter-hooks, uppercuts, and body shots. [1,2] The risk of the inside slip is that the defender moves into the path of the opponent's rear hand, making timing and defensive awareness critical. [2,3]

Outside Slip
GenusThe Outside Slip moves the head to the outside of the incoming punch (away from the opponent's centre), rotating the upper body so the punch passes over the inside shoulder. [1] The outside slip is the safer of the two slip directions because it moves the defender away from the opponent's rear hand, reducing the risk of being hit by the next punch in a combination. [1,2] The outside slip creates an excellent angle for counter-crosses and overhands thrown over the top of the opponent's extended arm. [2,3]
