I am looking for a detailed presentation of a typical beginner's class of hatha yoga which would last 1 hour and 30 minutes. Anyone can help me (which asanas, when, how to plan the class overall) ? Thank you !!

For a long class like that, I think it’s really good to start with at least fifteen minutes of breathing, followed by fifteen minutes of ground or floor stretches. Eventually, maybe through a downward dog walking to a forward fold, come up to standing and do some sun salutations and balances, followed by standing postures, for about thirty to forty minutes. Take five to ten minutes for backbending and five to ten minutes for hip openers and cool down. End with a reclined twist. Then you will have five to ten minutes for savasana. 

Shanti B.
