This was my second spin class ever. I recommend wearing a sleeveless shirt and something you're ready to sweat a lot in. It's great workout! That being said, it's nice that even though they encourage you to push yourself, they are very laid back. You don't have to feel like you have to keep up with them every moment. Everyone is unique and there for their own reasons!!! Bring a water bottle and your own towel(they have towels but yours is probably softer and smells just the way you like it).
