Get down on your hands and knees―your hands should be shoulder-width apart, knees hip-width apart. Move into the cat pose: Exhale and tuck your tailbone under, round your spine and drop your head as if you’re looking at your belly. Hold for one inhale and exhale. Then move into the cow pose: Inhale, then exhale and extend your spine, drop your belly toward the floor, lift your tailbone to the ceiling and look slightly upward. Hold for one inhale and exhale. Repeat 5 to 10 times.
