Scott provided me with an excellent post I put up at my blog that gives his insights on injury rates in strongman, Crossfit and strength training in general. This is a good read and may keep this thread active a bit longer.
"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."
There have been some good discussions on CF Radio after the Boyle/Cook criticisms of Crossfit on training for the military and reducing injury rates. There was a training officer who said that after implementing CF methodology he saw a dramatic decrease in the number of injuries. There was also a rebuttal about the benefits of high-rep Oly lifting, arguing that many people have to do technically difficult things when they're tired.
I don't know if I personally advocate it, but Grace is an a**kicker of a workout.
