Wow, 90 minute yoga class.
I've been doing 75 minutes classes...but what's another 15 minutes.
I'll have to research first if it's safe to do hot yoga with high BP. If not, then I won't do it. I've been doing yoga on and off for 4 years, recently been going full force for school credit. I love it! Especially, chavanasa (sp?) the end part.
