Amusingly enough, we just taught this in class last night. There are a couple of hardest places, but the one we want to focus on is that last movement when the leader pivots at the very end.

For Leaders: We want you to be aware of the way you can really get a tight hold of her back between your hand and your forearm and that's what allows you to get the energy through her to create the pivots. Also, when you are going to walk forward after that, assuming you are, making sure you flex with your right arm as your body goes forward, in order to make sure she goes back with you.

For Followers: In a very subtle way, we want you to shift your center of gravity just a tiny bit backwards, just in a normal embrace, and feel the way that this makes the connection between the leader's hand and your back more snug.
