Laura works with a rider who's goal is to have him working for her from the start of the ride.  She is schooling the movements of the Grand Prix, but can become backed off from going forward, and Laura works out a plan for keeping him forward first.  The rider always encourages him forward when she feels him back off, and gives the hand.  In the warm up they check the forwardness first in the walk through lateral movements.  In the trot, Laura guides her through an effective, elastic connection, making sure he's on both reins.
