I found this cue online and wanted to share since you always hear me talk about the hook grip when doing cleans and snatches.
“Peace Fingers” = Hook Grip
Hook Grip is used for the pull of both the clean and the snatch, this method of gripping is an eventual necessity to maintain control of the barbell during the violent explosion of the second pull.
How to do this:
“Press the webbing of the hand between the thumb and index finger against the bar; wrap the thumb around the bar as far as possible; grab the thumb with the index and middle fingers; use these two fingers to pull the thumb further around the bar; grip the bar with the remaining fingers.” Greg Everett
This should be done every time you work on snatches and cleans. Get used to it so it becomes second nature!
