for use of the pulling and and gripping how do you guys train outside of active grappling?
things that i have used am using:
hammers, small heavy one or sledge for single hand or whole body movement
kettlebells, ever since i started training with them my grip hase got alot stronger
sandbag, i like using it but i need some more ideas
old bicycle inner tube, one of my old chinese teacher told me to tie an inner tube round a tree and then practice diffierent pulling techniques, really works your fingers
