I can anecdotally say my body works the exact opposite: holding stretches is excruciatingly painful for me and I went from not being able to touch my knees to full downward dog in 12 months by doing very short (2-3s) but very strong stretches (like painful enough I would tear up). So I think every body is different and there is unfortunately no magic trick. But the author did one thing that applies to everyone: don’t give up; read up, keep trying new stuff.
