Of course there are excellent coaches in CF. But they seem to be in a dwindling minority. That video was not from a gym. It was from the SoCal sectionals. I have two clips from that event, and neither one shows even an attempt to get a tired back into extension. This has become the norm, I'm afraid, and it is justified by the work/time excuse. You know this to be true, and I'll bet you don't like it either.
