I have studied Iyengar, Desikachar, Jois, Kundalini, Bikram, on and on.
Here is my theory.
Any type of movement is good. Any type of stretching is good. Almost any type of exercise is good.
Aside from specific ailments such as bad back or pinched nerve or something like that, I think general exercise is generally good for the body.
In other words, for health and longevity, for the average person without those specific ailments, does it really matter if you do Sivananda yoga or general calisthetics? I don’t think so. I think yoga asana or taiso or pilates or any other type of general exercise would help keep the body in good shape. But will that alone not make a person live to 100. I think Mr Krishnamacharya and Ms Devi just had it in their genes to live that long. I think Mr Jois had it in his genes to live into his 90’s-- and Mr Iyengar, at least that long.
Did yoga help them live that long? Did yoga keep them healthy?
I believe yes and no.
Yoga is good for you, and it is good for your health, but it is not the end all.
So, does it really matter if you start your asana standing then go to sitting asanas? Does it matter if you do pranayama before or after the asanaa?
I don’t think so.
I think it is the practice of moving in general which is healthy.
