Outside Slip

Genus

アウトサイドスリップ(Autosaido Surippu)

Transliteration

Translation: outside slip

Overview

The 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]

Training Notes

The outside slip moves your head to the outside of the opponent's punch — away from their centreline and their other hand
Bend the knees and rotate the torso away from the punch — your head moves outside the line of the extended arm
The outside slip is the safer of the two slips — it takes your head away from the opponent's power hand
From the outside slip, counters include: rear straight over the top, lead hook around the guard, and pivot to a new angle
The outside slip of the jab is the bread-and-butter defensive move in boxing — slip outside, counter with the cross
Use the outside slip against the opponent's power hand (cross) to avoid their combination flow
The Philly shell/shoulder roll is built on the outside slip principle — the lead shoulder rolls the punch past while the head slips outside

Common Mistakes

!Slipping too far outside — this takes you out of counter range and wastes energy
!Leaning away at the waist — bend the knees, don't just tilt
!Dropping the lead hand while slipping outside — it should be available for a lead hook counter
!Not countering after the outside slip — the outside angle is prime for counter crosses and hooks
!Outside slipping when you should be blocking — some punches (hooks, uppercuts) can't be slipped; block them
!Moving the feet sideways at the same time as slipping — the slip should be a head movement with stable feet, not a step
!Slipping in the same direction repeatedly — alternate inside and outside to remain unpredictable
