re: Crossfit is a sham- as told by a crossfitter

The main reason I don't want anything to do with it is that unless you're in some rare profession/hobbby where a wide range of functional strength is needed, most people don't have need for what crossfit offers.

You want functional strength for doing x, y, or z, practice x, y, or z and it'll come. You want endurance? You want aesthetics? There are simpler, less injury prone and arguably more efficient ways to go about those.

It's an answer to a question very few people ask.
