This is asking your horse to cross and uncross their hind legs. This exercise tells you how your horse is currently feeling inside and can predict what may go wrong in the future. While it is called Disengaging, that is slightly misnamed because the horse is slightly moving forward – stepping up and forward with their inside hind foot – something they will not do if they are tense. Disengaging the hind end is one of the most basic tools you will use on the ground and one of the foundational tools you will use under saddle.
