This is a great thread.
I’m still in search of the perfect yoga practice. I’ve done mostly Ashtanga and more recently Power Yoga (which is based on Ashtanga). Although now I only average one or two sessions per week, I'm a big fan. If I had to enumerate the potential benefits:
- Meditation (not relaxation--they're different)
- Active recovery
- Alignment
- Flexibility
- Kinesthetic awareness.
There are also pitfalls. It seems to be pretty easy to become a yoga instructor, and yoga with a bad instructor is a good way to get hurt.
Ashtanga and Power position themselves as your primary workout, which isn't a fit for me. Also, there's not a ton of variety. For the kinesthetic awareness component, having variety in postures would be nice.
