They were saying there is a set of 7 breathing exercises plus, some light physical exercises. My mom had very high BP and now its much lower. Dad's arthritis is improving.
They are from North India. Although mom does yoga at home, dad likes to go to a park, sit under a tree and do his exercise. They are positive it has impacted their health positively. I am so happy for them, they have found something natural which is helping them stay away from allopaths.
