This is my favorite yoga DVD. I don't know how they could have made one more perfect. I have been doing pilates since its conception and thought yoga was just a watered down version of pilates until I discovered Ana & Ravi. This whole approach was a revelation to me with all the dynamic moving and breathing in sync.I also thought I had reached the limits of my flexibility but the focus on releasing the solar plexus, spine and core using movment & breath to give the body an authentic release was a real eye opener for me.I plan to try their Navel Power next and hope it is more of the same!
