Heh, a bit of bluster there, no? If I had to re-write that now, I would say we do not routinely recommend stretching, meaning static, band-assisted, PNF, or similar modes that most would consider conventional stretching. We don’t recommend it because it costs time and doesn’t seem to do anything with respect to reducing soreness, improving recovery, boosting performance, reducing injury, and so on. If people want to stretch because they like the way it feels, that’s fine. I don’t think stretching has too big of an impact on strength development long-term, if any, but would generally not recommend it before training.
