Double

A double left: 1 - step forwards onto the toes of your left foot, raising your body, and bringing your left shoulder forwards (with the whole left side of your body), 3 - step forwards onto the toes of your right foot, still leading with the left side of your body, 4 - step forwards onto the toes of your left foot, left shoulder still in front, 5-6, slowly bring forward your right foot, until it's just above the ground, ready to take the next step, while slowly lowering your left heel, and beginning to straighten up your shoulders. 

Note: a double counts as one step (with three movements), so you rise and fall only once over the whole double (up at the beginning, down at the end), and lead with the same shoulder through the whole double (even though that means there's a point in the middle when your feet are doing one thing and your torso, another).
