As a 15+ year Yogi (who practices regularly, well at least until C19!) I've never heard of these either!

According to Wikipedia:

  * Hatha is seems to be a branch of Yoga (Hatha apparently means "force")
  * Ashtanga is another type of Yoga brought to the modern world by Sri K. Pattabhi Jois and involves synchronizing breath with a series of positions.

Interesting ... I'll have to look into them!

Yes, thats a fair point, I will add something to help explain each. To be honest I had never heard of Hatha until I started building this, but as I aggregated the data it is a keyword that came up quite a lot. Thanks for the feedback!
