Hi Stephanie -- just saw that you're taking your first spin class tonight. I wanted to stop by and wish you luck. Try not to be nervous; there are plenty of other new people in class too and everyone is usually too busy worrying about what they're doing to pay attention to you!
I just took my first spin class (30 minutes) at the beginning of January. I was really intimidated too, but after doing it every Monday (at 6am!) for the past three weeks, I'm loving it so much that I'm adding a 60 minute class this Thursday. Little nervous as to whether I can go for a whole hour, but I'm committed to at least give it a try!
I know you'll do great, so no worries -- just enjoy yourself!
