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.
I’ve always heard that people who consistently always stretch and people who consistently never stretch are injured at lower rates than people who inconsistently sometimes stretch. But I don’t have a study to back this up
I’m inconsistently consistent, so I’m fucked.
