>>76347096 (OP)There is no such thing as "outdated" when it comes to physical training. Humans haven't changed so much that what was true in the past suddenly isn't true now. While there are studies that have shown static stretching doesn't help performance as much as we once thought, these studies, as with pretty much every study in exercise science, measure degrees of significance that would only EVER matter to professional athletes. So no, nothing is outdated and there is absolutely nothing wrong with static stretching.
