- Hi, I'm Shauna Smith-Yates. And today I'm gonna be taking you through a quick core using your box and pull. So let's get started. We're gonna take a breath in and as you reach out, you're gonna reach your top arm overhead and your bottom arm around your belly. Then from here, you're gonna go further over your box. You're gonna come back, all the way up. Flex to the other side. Inhale, come back up top and take an extra breath. Here we go, we'll do that two more times. We're gonna inhale two, three, four, five and exhale. Two, three, four, five. And two, two, three, four, five, and exhale. Two, three, four, five and three, two, three, four, five, and exhale. Two, three, four, five, and, pull in your abdominals. Lift your knees off to a hover. Imma take it out to one long line, and then I bend my knees back in. One.
