I believe it was in Supertraining (the book, not the gym) where they pointed out that in the absence of any dynamic work, as the body gets stronger and stronger it will also perform slower. So that's where the dynamic work really comes into effect.

How do you all vary your DE work? In my experience DE work needs to be varied all the time to keep you moving forward.
In the beginning I ran 3 week waves for squats and bench and only pulled for speed every 4th week (Between squat waves). Now I typically incorporate speed work every other week and just keep it different each time. On the off weeks I do more BB/hypertrophy work (always trying to get bigger).
