I wouldn't say periodization is evil, lol- unless it was enforced with physical violence. But, my criticisms of the *model* have nothing to do with what coach is using it. I simply believe a more anarchistic approach is more effective- most especially for the talented and young who are inevitably held back by periodization.
If things get stagnant, it means we are ready for a bigger training load (plus, exercise selection, exercise order, training intensities and volume can vary week by week, which can prevent staleness.).
Here is the better question! If we can train the Snatch, Clean+Jerk, and squat simultaneously, why the heck would we need to divide our training into different phases??
