Not late! When Rachel does the tail grab, she reaches close to the feet. As she kicks the legs back toward the wall behind her, she lets the tails slide through the hands just until the knees extend and then holds tight, allowing the feet to pull the hips over. Once the hips rotate back, extend the tailbone towards the floor, press the feet into the tails, pull the chest upright. See if you can use the tension between the tails, hands, and legs to give you leverage.
Happy training!
