I took Viv's spin class tonight and I must say she is bad ass. I have not been to a spin class in a very long time so I met her there early and she got my bike all set up for me. She is great spin instructor and does not let you slack fo sho. I am a little sore in the "girl area" or "the Gina" as Marcy would say. Thanks Viv for a great hot and sweaty leg burning work out.
