I used to do vimi yoga. It's a gentle slow one which can be tailored to your needs and abilities, the movements are all anaerobic.
I couldn't hack the so-called "spiritual" side of it at all. I'm an aethiest, so my brain went into it's usual analytical mode and I was working out the biochemical physiology of what my body was doing... the "spiritual" explanation was just irritating nonsense which got in the way of achieving the correct sort of calm state I did get from understanding the physiology.
One time, our teacher said; "Now, just imagine you have a fluffy little chick in each palm of your hand.."
I'm afraid I collapsed and snorted loudly. If you have a fluffy little chick in each palm of your hand... you have two handsfull of chicken poo. Been there, done it, had the handsfull of (very runny) poo!
The breathing exercises which went with the "spiritual" stuff just made me sweat and feel lousy. I only did them in class, not at home. Social pressure!
Sadly, I had to give it up. It involves too much arm raising. I only have a limited amount of arm-raising capability and it is needed for laundry and dishes.
