I finally tried Spin class. It was hard and challenging but I am happy and proud of myself that I did it! After a 45 minute class I was a sweaty mess and sore! Those seats aren't very big. If I get serious about spin I think I would invest in some padded shorts. It was great to go with Jen she is a great workout buddy. I will let you know how I feel tomorrow. I posted on Facebook that I tried it for the first time and I had a lot of postive responses. I am really lucky to have a good support system.
