Excellent yoga classes
This app has lots of different classes that you can download (flexibility,strength, balance and relaxation) and offers different lengths as well ( 10, 15, 30, 60 minutes)
The classes use a combination of still images for held poses and video for movement between poses. I think that is how they keep download sizes relatively small despite the HD quality.
You can also create your own routines by choosing poses from the apps list. The really cool part is that the app will automatically insert intermediate poses in between your chosen poses if they dont fit together smoothly.
Some people have complained about the music, but it never really bothered me. The ability to add your own playlist would be a cool feature to have though.
