Don't knock it 'til you've tried it...this coming from someone who didn't take her first class until age 49!
It's never too late to start.
If you ever want to do a class, you might start with the 10 am Sunday class (every other day it starts at 9 am). I haven't been to that one, but I've heard it's a "restorative" class, a little more mellow, with more emphasis on relaxation and flexibility. Sounds like it might be a bit easier for a beginner. I've heard that Wednesday class is the most challenging and fast-paced. I haven't tried it, but it's packed when I ride my bike by.
