Laura has them work on the walk while the mare catches her breath, and gives great tips on riding the transitions from the walk to the free walk.  When they return to the trot they perform a shoulder fore.  They use counter flexion to bring her shoulders to the inside.  Laura helps him correctly place the barrel in the haunches in and not lean on his inside leg.  They let the mare have a good stretch to finish the session while Laura describes how leg yield and haunches in are differing skills.
