Downward Dog

Begin on your hands and knees with your hands shoulder-width apart and your knees hip-width apart. Spread your fingers wide and press down into your palms, making sure that your fingers are evenly spaced and facing forward. Tuck your toes under and lift your knees off the ground, straightening your legs as much as possible. Press your hips up and back, bringing your body into an inverted "V" shape. Keep your arms straight and your shoulder blades spread apart, and try to press your heels down towards the ground. Hold the pose for several breaths, then release and return to your starting position.
