Before I post the video, I want to say, I grabbed the wrong side reins and they were way to short, so I had to improvise, if I lunge her with nothing she just keeps throwing her head up and down looking for contact.
Anyway, to me it looks like there are moments when she is engaging her back, but I really wanted other opinions. She hasn't been ridden since october(long story) now that the weather is finally nice and the ground has firmed up, I'm finally starting to work her again. This is only her second time being lunged since her time off so she is a bit out of shape. I'm doing short sessions to start. I lunged her first and then my friend took over(partly because I'm terribly uncoordinated lol) so I could film.
