This is the unedited version of a video I found on youtube right near the start of this year, the other was removed.
I find it quite strange watching this. While I feel sorry for the kids and what they are forced to do, I go to training four or five days a week and ask people to do these same things to me. Last night we were doing partner stretches and the person I was working with was too scared they would hurt me and so hardly helped with the stretch at all.
