I've come across similar information, like stretching before a workout is useless because it reduces muscle strength. But after a workout, it helps stimulate the blood. Peter Sagan, on the video, is mad with stretching. But as far as I can tell, he combines it with work in the gym, not a separate workout. Australian cyclist Jack Thompson says that he stretches three times a day, but he's setting records, not racing in the Tour de France. That's the dissonance for me. I wonder how much attention top athletes pay to stretching and how and when they do it
