CF can be good and it can be bad. It's not really anti-CF more like anti-silly shit. The main page WOD and the way it's "programmed" is not optimal and a good way to get hurt like Derek said above. That being said there are some affiliates that do have good coaching and good programming because they don't just focus on the main page WOD. They take all the good elements and toss away the bad.
"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."
