Could start from pos 2, or a hip twist changing from fwd ochos.
Do collect feet, but not too early, wait (can keep some foot pressure on floor) till Man leads the ocho turn. For Back Ochos, it's easier to bend the knees and collect, then swivel.
Upon Man's lead, start rotating body first, keep frame to Man, then start rotating hip as you collect foot, then swivel foot when feet are already together. Do not collect feet too fast.
Keep head at about same position, it does move a little, but less than body, don't flip head back and forth. Eye focused on Man R upper chest area.
Can finish with a lock and resolution, Or with twist to switch to fwd ochos. Listen to lead.
Weight is always a bit more fwd, never back. Pay attention especially when it's backward steps, pitch fwd, do not lean back.
Rotate/swivel enough. Step bigger back step.
Generally, if Man lower's Lady down, Lady takes bigger back step (likely preparing for Gancho)
Don't take arms with you, give arms to Man.
Focus on twisting hips, less upper body movement. Hips almost to 90 degree to Man. Twist hip as much as possible to keep movement in front of Man and not traveling backward much at all.
Embellishment: leave the free foot to wrap around standing foot for a bit, bound off the standing leg, a little ronde out to cross back and step.
Start at position 2.
Leader lifts follower to stop movement (collect), changes weight to RF.
Pulling back left shoulder blade, and allowing right arm to slide away from follower's back, follower is lead to swivel left on her right foot.
Leader steps left, collects, pull right shoulder blade back, slight pressure on left hand, to lead follower to swivel 180 degrees right.
Repeat doing 4 ochos. Always an even number.
On last ocho, collect. Follower's left foot will be free. Continue Salida stepping with right foot, go into cruzada and resolucion.
