I've just done the WPC worlds and found out my hands are too weak, both in terms of grip strength (I thought it was ok) but more evidently my actual skin strength.
My third pull literally ripped two massive chunks off my left hand causing me to drop the bar almost at lockout. It's growing some skin over now but it's a little thin still.
Any tips to toughen up my palms?
Also what grip work do you guys find most useful for deadlifting?
