The main issue I take with crossfit is the programming. Bad coaching and a prevalence of speed and reps over form is one set of problems but perhaps greater is the intrinsic lack of good solid progression in the workouts.

A lot of these people are more or less wasting their time grinding out workouts that have no real rhyme or reason to them when they could be putting all that perspiration into good linear progression and actually increasing their strength and performance.

There's also a pervasive smugness in a lot of these boxes. It almost seems to be part of the workout; thinking you're some kind of superhuman and better than everyone else.
