Yoga Balls & Downward Dog
BKS Iyengar asserts that this asana stretches the shoulders, legs, spine and whole body; builds strength throughout the body, particularly the arms, legs, and feet; relieves fatigue and rejuvenates the body; improves the immune system, digestion and blood flow to the sinuses, and calms the mind and lifts the spirits. But it sucks if you don’t know the ins and outs of the pose. Often called a resting posture, it can seem anything but.
