Because of the above, even after fews and years of practise sun salutations never become easy and they remain a work in progress, something that can constantly be refined and deepened. In terms of movement they contain most of the elements yoga practise; the deep forward bend, back bend, hip opening, and arm balance. In fact probably the most challenging of all arm balances in Ashtanga yoga resides hidden away in the sun salutation.
Here is a short video of one Russel Case doing doing them brilliantly (but when you do yours don't arch your back so much when you lift your arms) - sun salutations.
