So why lunging you asked?
“With the rise in popularity of natural horsemanship methods where the horse is usually worked loose in a round pen, the tradition of lunging a horse as the basis for its training and preparation for ridden work has perhaps lost popularity in recent years. However, lunging a horse properly has certain attributes which make it gymnastically a far superior method of training to loose work”.The size of the round pen has a lot to do with the age of the handler. Way back In my twenties I worked my horse in the 60 feet round pen, now in my eighties I resized it to about 40 feet or maybe even smaller.
