Kneeling cow and kneeling cat provide arches and curls that flex the spine, massage the belly, and help release serotonin, the mood-regulating chemical that takes from grumpy to good!
Start on hands and knees, fingers spread. Inhale and arch back, tilting sitting bones up. Pull shoulders back and look forward.
Exhale a you round your back. Tuck your tailbone, letting shoulder blades spread and drop chin toward chest. Draw in toward your navel. Repeat until you bust your bad mood!
