Yoga lesson

My wife has asked me to accompany her to yoga lessons. She has many ways of making me do her bidding! It was week 2 of a beginner class. We are supposed to be on trial lesson to see if we like it. There were 6 women and 2 men. The other man belong to woman in the class. It feels a little awkward to be under-represented in the class. We learn 3 postures - corpse, salutation and lotus. There are also explanation of the benefits of each posture and an introduction to the layers of mind (prelude to meditation next week). The class lasted two hours. As I go through the class, it seems that it may help my backache. So I asked wife to sign up for me as well.
