It looks very plausible that stretching before you exercise doesn’t do much for you. Multiple older surveys suggested this.
Annoyingly, the studies linked in the previous paragraph are 2 decades old, and somehow I can’t find a large, well controlled, trial.
Heard something recently that suggested extending your range of motion alone doesn’t help (maybe even makes you more susceptible), but pushing against the stretch to build strength athe same time seems to help a lot. I can relate personally, but would love to see solid evidence.
