I'm pretty sure this practice is still common. I know of no parent who'd think their kid was being bullied for having to run a lap or two because they were late to practice. As for it being counter-productive, there are two sides to that. There's definitely a counter-productive element, but there's a productive one, as well. And whether it's productive or not isn't really relevant to this point. You've already said sports aren't cults, yet coaches resort to many of the same practices as MA instructors. At worst (if we go with your assertion that this is not common practice in sports now), MA instructors are behind the times.in past decades maybe,but its a) counter productive as above and b) would be considered as bullying in the century. Arguing that people used to do bad things to children in the past doesn't really support your point to well
