Yes, of course, stretching not only helps to make the body more flexible, but also helps to improve joint mobility, faster recovery after workouts, muscle relaxation after strength training and so on. All in all, the benefits of stretching are huge. I myself have recently started stretching in the studio stretching coach FlexDerek https://flexderek.com/en/stretchingonline/ and began to notice that my muscles, as well as ligaments and tendons have become even stronger, and thanks to this my strength performance has increased many times.
