So for this next move, she's gonna stand nice and tall. Her one leg extended. Heel is flexed. She is pressing into the ball. Arms are reaching. Take a breath in and just drop down bending that standing leg. Ball is gonna roll forward. Arms extend. Good. And then exhale. Pull the belly in. She's gonna slide the shoulders down and really contract those abs. Do it again. Take a sit down, flexing the foot. Balance. And then exhale. Nice and [unk].
