I don't know how many people out there have ever gone to a spinning class but I partook in my first one last night. One word, INTENSE! I don't think I would have been so exhausted afterwards if I hadn't gone for a swim and run beforehand. I didn't plan on doing the spin class, I kinda just happened to be in the right place at the right time. Or the wrong place at the wrong time. 6 months ago it wouldn't have been a problem but I'm in the process of getting back into shape. Needless to say, last night I had trouble sleeping. My legs were sore but in the way where you feel it but no amount of stretching will help. They still feel out of sorts.
I never thought there could be so many hills when riding a stationary bike. AND when you ride a spinning bike, you can't just stop peddling like a normal bike. Everything is connected so if you stop peddling, everything stops which is like trying to put your car in reverse when driving down a highway. I'm sure I'll get used to it and learn to enjoy the intense burn when climbing those imaginary hills. It's great because as soon as I walk out the gym, I've got a 70 degree hill to climb on my way home.
