Inside Slip
Genusインサイドスリップ(Insaido Surippu)
TransliterationTranslation: inside slip
Overview
The 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]
History & Origin
Effectiveness
The inside slip is effective against straight punches (jabs and crosses) by moving the head to the inside of the incoming punch, simultaneously evading the strike and positioning the defender for counter-hooks and body shots. [1] However, slipping inside carries greater risk than the outside slip because it places the defender in the path of the opponent's rear hand. [2]
Lineage
Slipping is one of the oldest defensive techniques in boxing, described in early prizefighting manuals and refined throughout the 20th century by defensive boxing specialists. [1]
Competition Record
The inside slip is a standard defensive technique in boxing and MMA. [1]

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
Variants
Inside slip — moving the head to the inside of the incoming punch
Outside slip — moving the head to the outside of the incoming punch
Bob and weave — ducking under a hook and rising on the other side
Pull-back — leaning the head and torso backward to make the punch fall short

✓The inside slip moves your head toward the opponent's body, inside their extended arm — ducking under and inside the punch
✓Bend the knees and rotate the torso toward the opponent's centreline — your head moves to the inside of their punching arm
✓From the inside slip, you're positioned for body hooks, uppercuts, and clinch entries — it's an offensive defensive move
✓The inside slip is the classic counter to the jab: slip inside, then land a rear straight or lead hook to the body
✓Inside slipping requires controlling the distance — if you're too close, you walk into the opponent's other hand
✓Use the inside slip sparingly against orthodox opponents — it puts your head on the line of their rear hand
✓Drill the inside slip against a partner's jab: slip inside, counter with the cross, immediately return to guard
Common Mistakes
!Slipping too far inside — you end up directly in front of the opponent's rear hand
!Not bending the knees — the inside slip should lower your level, not just lean sideways
!Dropping the rear hand while slipping inside — the rear hand must protect the chin on the inside
!Staying inside after the slip — return to centre or clinch immediately; lingering is dangerous
!Inside slipping a hook — inside slips are for straight punches; hooks require bobs or covers
!Not countering after the inside slip — the slip creates a counter window; use it
!Using the inside slip against a southpaw's cross — this puts your head directly in line with their lead hook

Frequently Asked Questions
What's the correct foot position for an inside slip?
Position your rear foot in line with your front foot. When you slip to the inside, you'll be slightly off-balance, so proper foot alignment is essential for maintaining control.
What should I do after I land a body shot following an inside slip?
Go back down to the body again. After a good body shot, repeating the same target—finishing with a combination like a one-two followed by another left body shot—is the most effective follow-up.
How do I generate power in the counter-punch after slipping inside?
As you drop down to throw the shot, pull your rear shoulder back—that's what launches the punch. Load your rear leg and engage your core ('put the engine back in the water') to drive power into the strike.
