Steffen Peters watches this pair warm up at the walk and explains what he is looking for as he watches a new horse. He talks about finding the right tempo for warming up and how that is different for each horse.  He helps her through a small spook by asking her to yield to the inside leg on a small circle.  They check out the shoulder in/shoulder fore and then change direction on the long diagonal, asking the mare to go a bit more forward and then back on the diagonal.  Steffen explains how he asks his horses for the half halt and what he expects.  He asks her to keep the mare supple on both reins. When they ride transitions within the trot he has her tap the mare with the whip in the half halt to the down transition to keep her hind legs active.
