Learning the "hook" grip
One of the most important components of lifting anything is grip. I have smallish, pudgy hands. The bigger the hand, the better the grip - Not a good thing for me. But so what... I have to work at it more thats all no excuse. I do static holds (just hold a heavy barbell 80kg or more in each hand for time) and wrist work. BUT the main thing that has helped my grip especially in the olympic lifts is a technique called the "hook" grip. As you can see in the picture above, the thumb goes UNDER the fingers, and the first and second finger press down on the thumb. This prevents the bar from "rolling" out of your hands. Thats GREAT news. The bad news is that it HURTS to do this. But with practice, the pain becomes normal and tolerable (took me 3 weeks of practice 3x a week to not notice the pain, but its 3 weeks well spent!).
