I had meaning to take some yoga classes. For years I have been feeling very stiff. I try to do some light stretching about twice a week. If I don't do that then I walk even slower than normal.
There is a place called the yoga loft which is close to the Drake's Circus and University.
I went to the beginners class obviously. It was a strange evening weather wise. It was both hot and the air was full of thunder. I started to sweat like a pig. I had most problems, both flexibility and strength wise with the leg stretches. There were some very useful yoga bricks which helped with stability.
I am not in the photo below, but you see it is very good place to practice.
