It's generally a good idea to train dwarves to legendary in wrestling before handing them any weapons. Severely cuts down on accidents.
there are two schools of thought on this. while legendary wrestlers will be more capable of dodging incoming blows, and *should* have higher toughness (and stats generally, all being well), they will also be stronger and thus more capable of doing
serious damage. putting a sword/axe/hammer in the hands of a glazed-eyed toughie who is used to tearing gobbos limb from limb with his bare hands is potentially more risky than arming raw recruits who, even if they accidentally hit each other with their weapons, will only do very little damage.
for this reason, if i am drafting new recruits into my military, i put dok and rov, my two legends, out on patrol, just so that they don't hold a military induction day at the barracks and cripple 85% of the newbies. the newbies get to train up a little in wrestling, to facilitate dodging, and hopefully gain some toughness, and then get weapons and i wait until they have some armour and shield skill before letting my killing machines anywhere close to them, no matter how noble dok's "training" "plan" is
(effin psycho...).
i've heard of people who also have silver or wooden training weapons that will obviously do less damage, so that when first introducing weapons into the mix, there are less likely to be those "whoops, i slipped with my steel battle, wait, sh*t, your leg, it's halfway across the barracks! oops!" incidents...
edit: clarity check.
