That was my response as well, though I'd say that if you find that to be troublesome you can just ignore that from the book and just look at the rest of the, in my opinion from reading so far, good material. I was honestly very surprised to see that. I guess, I don't discount everything that someone says if I think they're wrong about a specific thing, and in sports science there seems to be a lot that is continuing to be discovered and argued about. It's a fluid field.

I will say throughout my life I have heard a lot of conflicting advice on stretching. "Don't stretch before working out", "Don't stretch after working out", etc. and I personally just do dedicated yoga sessions with deep/long poses for my stretching and that's it. I'm not sure "the science is settled" there so to speak, but my own personal results suggest that stretching is beneficial and helps prevent injury.

The author is Kelly Starrett, a legend in the physical therapy/movement world. I've read a lot of his work.

I don't think his message is that stretching "does nothing". It's more that, research has shown that combining stretching with strength (using the range of motion) is the way to create lasting change.

I may be misremembering but I thought his wife and him (since they are co-authors) explicitly said something along the lines of don't even bother wasting time stretching. It's near or at the beginning of the first chapter. "Do it if it makes you feel good but it's a waste of time" or something. Please correct me if I'm misremembering or outright incorrect. I don't have the book nearby to check.

Historically his perspective was that it wasn't necessary. If you're getting full range of motion exercise, you don't need to stretch, because the exercise itself is doing what needs to be done.

Right. Personally I've observed my squat form and ROM are much better if I stretch my hamstrings first. So I stretch first to get more benefit from the exercise.

I bet it changes based on a few factors including age, prior mobility, etc. I do a few things at my current age:

  I wear Vibram "toe-shoes" so that my heel isn't lifted off the ground when I squat or do other movements and unless I'm lifting very heavy I go below parallel
  I warm up by doing either some prescribed warm-ups or by getting on the air bike/rowing for a few minutes + other warm-up activities
  I do the exact exercise movement I'm going to be doing if it's a movement like a snatch, clean and jerk, deadlift, squat, etc. to warm-up 

I don't do any stretching before or after. It's absolutely fascinating that so many different things work for so many people.

yeah your hamstrings might not be so tight, you may have different ratios in your leg bones, who knows! lots of anatomical variation

> If you're getting full range of motion exercise, you don't need to stretch, because the exercise itself is doing what needs to be done.

I dropped powerlifting when gyms closed in 2020. I picked it back up recently. With a garage gym it's now so easy to lift without so much dang ceremony, just warm up through the exercises themselves. Sessions all under an hour, PRed all three lifts at my meet, and never got a red light on squats when I used to get one for depth on one side all the time. Stretching is all time fake in my book.

I could see "it does nothing for you" for some set of things, but it cannot possibly be absolutely true. For one thing, stretching has been very successful in increasing my range of motion. It may be, however, that it e.g. doesn't do much for reducing, say, back pain or improving overall health outcomes

It clearly does something, but it's possible that in the context of the claim it does indeed do "nothing" (nothing, or so close to nothing that it might as well be nothing, to affect the specific things in question)
