Once Bizzy had gotten used to going over crossrails while she was on the lunge line, Lauren and crew took her to the indoor to do something called “free lunge.” The person still stands in the middle with a whip (used to guide the horse to stay out on the perimeter) but the horse is not wearing tack or attached by a line.

They set up a line of crossrails, and you’ll see in this first video that Bizzy took to it.

Eventually, they added a couple of low verticals.
