It's been a long time since I've been in a spin class... over a year. This morning I went to one. I lasted 30 minutes before I started dry heaving and thought I was going to pass out. I got so hot and felt not good. So I slowed myself down (hello Mel, you just got back to it, stop being a superhero and keeping pace to the uber spin chick next to you) and quietly left.
I even forgot my waterbottle. DANG IT ALL!
(actually that is okay, I hated that water bottle anyhow!)
