Hitting an arctic ogre lord will do the trick as well. Soulstone on spellweaving or get a friend to get you an arctic ogre lord. Just make sure to heal it every now and then as you will do a little damage with wrestling. It will take a little time but an easy macro can be set up for it.
I'm not sure if it still works, but it used to be that if you equipped a spell channeling fishing pole you would swing at 1.25s even with low dex. If that doesn't work anymore just temporarily increase dex for training purposes.
