I'm an amateur bodybuilder and I workout alone. Over the years I have contemplated joining Crossfit (mostly for the comradery aspect), but the insane level of cult mentality has made me shy away from it every time. Articles like this just drive home the point.
My friend Jane, who is a physical therapist, specializes in exercise injuries. She once confided in me that local Crossfitters form by far the largest percentage of her repeat customer-base. She said she finds the level of irrationality unbelievable, in that the same people will come to her in a lot of pain and brag about their injury on the one hand, and beg her to fix them up quickly so they can go back to Crossfit ASAP. Then they will come back in a few months with a different injury but the exact same mindset.
