LRG demonstrate walls and hits on BBC Sport, November 2015

Blockers can be most effective when they work together.

The London Rollergirls are back to give us a video tutorial on how to perform a successful Crabwall.

A Crabwall is a defensive wall formation, covering the track in order to stop the opposing team’s Jammers from weaving through and scoring points.

There are three Blockers and a backwards facing Blocker providing extra support and strength as the Jammer hits.
