I don't know about all that stuff...I like KB's for conditioning I just don't like using my arms for swings and I don't like teaching swings above shoulder height because it encourages arm use.
That logic seems silly:
Since sledgehammers are used to drive big spikes in the ground...I guess I shouldn't be using that for conditioning?
"And for crying out loud. Don't go into the pain cave. I can't stress this enough. Your Totem Animal won't be in there to help you. You'll be on your own. The Pain Cave is for cowards.
Pain is your companion, don't go hide from it."
