I don't know anything about the P90X yoga video, but I highly recommend Eoin Finn's "Power Yoga for Happiness" DVD. The routine as produced is 80 min long, but it's very well-chaptered and contains four additional practices from the same footage, each with a different emphasis. His hip openers are particularly good. The background yoginis demonstrate a variety of levels. I find this practice to be challenging, invigorating and relaxing as only yoga can be.
Here's a list of the routines included:
- Total Happiness (80 min)
- Magically Hips (55 min)
- Strong, Free and Happy (53 min)
- Daily Dose of Bliss (40 min)
- The Quickie (30 min)
Or you can use the chapter points menu to skip around the routine. I think the DVD is around $20-25 and is available at Eoin's website and at Amazon.
This morning I did the Cardio Conditioning Premix from KPC followed by the "Magically Hips" routine. Somehow this practice really does make you happy. (And I was in a bad mood when I started!)
