He didn't mean that. Many helpers tend to dance around to animate it.I assume by that he meant, he doesn't fight the dog constantly... I don't do that myself... a) can't, I don't weigh enough that it could last, and b) largely owing to many years of studying jiu jitsu, I understand the merit of not meeting force with direct force.
Elmar told us to stand next to the dog / pup and remain still. He worked the dogs from this position. He is an extremely competent helper and breeder - he has the brains and uses them to work the dogs.
There are enough muscled helpers around who use physical power instead of mental power.
