Yoga and I do not get along anymore as I was in a Vinyasa Flow yoga class when I injured myself (handstands and crow pose, some obvious no no's now)
My neurologist suggested Tai Chi as a very good alternative because it incorporates a lot of the mind clearing and medatative aspects, and is very gentle on the arms, but good for the legs. I am still looking for a class that will fit my schedule, an hoping it will be easier in January.
I have done many kinds of yoga including Bikram (done in a 110 degree room) A note on that kind of hot class- definitely bring your own mat and wash it afterwards!! One of the last bikram classes I took was on a day when the studio's heater was broken. The stench of the room (it was carpeted) was enough to turn me off forever. The warmth really helps harbor the bacteria.
Anyhow, I have (and still do) mourned the loss of my yoga classes..but I can't possibly do it anymore.
