Surya Namaskar, the Sun Salutation, is a series of 12 postures performed in a single, graceful flow.
Each movement is coordinated with the breath.
Inhale as you extend or stretch, and exhale as you fold or contract. The Sun Salutation builds strength and increases flexibility.
Different styles of yoga perform the Sun Saluation with their own variations.
This is a great series to do if you are just beginning yoga or want to create a daily yoga practice.
