I don't have a routine other than walk for 10 minutes on a loose rein. From there I let my horse tell what we're working on that day. Some days he's stiff as a board, so we do lateral and suppling exercises. Some days he's dull to the aids, to we work on going forward. If there's extra gas in the tank, then we do something fun like canter/trot/canter transitions or lead changes. The other day we were both in a goof off mode, so we went into the woods and did some trail riding.
