One of my horses lunge OK. Not extremely happy about the hard work (lol), but does it. My other one though doesn't want to lunge at all. She turns to me and just stands. Plus she tries to stay closer. I did try whip and rope and sounds, etc. etc. whatever I could find in books. But she just stands. When I lead her she leads OK. The moment I stop and try to make her go in circle around me, she stops too and turn her head to me. I did try to walk her in circle, she walks fins up to the moment I stop. Any advices?
