I've been doing Judo a few months now and I always thought that I would need crazy grip strength. I've found however that with 10 years or so of lifting, I'm not having any trouble with my grip. Do the grapplers here do anything specific for their grip strength? I've always been a fan on towel pull ups and I've been using thick bars for a few years from time to time. Also can anyone actually do a crossed arm towel/gi collar pullup? I tried them after seeing them in Training For Warriors, I cant do 1 rep as I just spin around!
