it may be prudent to post this on the sports/martial arts board as there are guys there that don;t usually post here etc
i would have thought grip work, strengthening the lower back and abs, general heavy compound lifts for the whole body (inc. legs) and developing explosivness (to shoot out for the grapple?) may help
i train far more frequently in striking+locking techniques than on the floor grappling so im not the best qualified to answer though....
I would say speed work would help. Extra strength will be great for Judo. Try asking Thaibox for some pointers he used to fight professionally iirc.
I would also say - make sure you eat enough carbs. Martial arts will affect your ability to put on size if you let yourself go catabolic as there is a LOT of aerobic-type work involved even in judo and jitsu.
bruce used to do good mornings, hell he even rooted his back doing them (subjective to some peoples opinions). I'd say hell yes to good mornings, but watch the weight.
For grappling, I would suggest cleans, for lower back strength and explosiveness. Also squatting for leg drive. I realy think deadlifting would hel a great deal since it works grip strength and overall strength for your core....
I still can not think of any better training routine than WSB for about anything. You need good hip and back strength. I think that WSB could really help with this.
