I find dynamic stretching to be much better, especially for shoulders. But I still floss my calves, as well as utilize rolling with a tennis ball to remove tension in my chest, glutes, triceps, and forearms pre workout. I only really use static stretches when specifically targeting the piriformis muscle area, as this has recently been a lifesaver in terms of lower back wear and tear. And I only foam roll my quads/hamstrings following sessions and days off.
