What exactly was your purpose of the you tube video? I don’t mind leaving people to observe and come to their own conclusion, but this post left me wanting more.
Drut was using very a dynamic warm-up in the 1970s. He was using very nearly ballastic stretches (I am a fan). His movement patterns were excellent. In fact, I am downloading the mp4 version of the video to use for visual modeling for hurdles. Why is it we regressed in the 80’s till today to using static stretches as a warm up? Despite it’s old school feel, it felt new, fresh, and reassuring. Although I don’t see a correlation in the video to screening.
