See the little glimpse of a crotch rope? It’s pulled in tight. And the rigger used it perfectly. Chrissy hands are pinned in place by the crotch rope. Wherever her hips roll or thrust it doesn’t matter, her cinched up hands are staying exactly there. Plus, the crotch rope is also that super short tether to the ultra tightly tied ankles. So as she kicks her legs looking for slack she’s actually tightening the cinching of her wrists.
