Speaking of Eric Cressey...here are his thoughts on CF for Basebell http://ericcressey.com/crossfit-for-baseball
"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."
