Carl now works with his rider on suspension in the trot.  He first looks at his medium trot and his ability to lengthen his trot.  They do three steps of medium and then back without restricting with the hand.  They make sure that he moves forward from the whip to an allowing hand, and then capture that energy in front for more collection.  They demonstrate the steps for building a passage.  He asks her to go to rising trot when they ask for more collection.  He has her ride the trot she would ride in a test, but when they go to shoulder in he goes more on his forehand.  Carl has her ride a diagonal to help with the shoulder falling out.  When he shows he's tired by lowering his poll and self carriage, so they allow him to trot on a long rein with suppleness.
