Re: Stretching
Surprise surprise the water boy doesn't know all.
Here's a decent primer.

But bottomline, it increases ROM, this is not disputed by anyone that understands science. So if you need to increase ROM for anything specifically, you need to stretch. If not, then you don't.
There are mixed results with regards to injury prevention. So this aspect is unclear and like many things will vary according to individual since there are a ton of other variables to control for. You're not going to get a clear result from any single study.
There's a reason it's used in rehab for hamstring injuries. But I guess the doctors must be wrong and we should trust the word of the waterboy.
If you need to increase ROM, then it is beneficial. i.e. gymnast, BJJ practitioner.
If you're just an avg gym bro w/ no special needs then you likely don't need it.
But to say that something is fake just because it doesn't apply to you is funny.
He probably heard someone say it one time in passing on some BBM podcast and extrapolated it to mean it's fake.
Fake weight loss, fake strength, fake stretching. Everything is fake with this guy lol.
