Query: Repetitious and Boring

It's not yoga - it's hyperventilation combined with a repetitious single movement. For example, sit with your arms straight out, looking over the left hand, inhale. Now curl the hands in to touch your shoulders, exhale and whip your head to the right. Now left and inhale, right and exhale....and repeat for 5 minutes. There, I've saved you the price of the DVD. It's by far the worst yoga DVD I've ever purchased.
