If you like a really intense workout, this is definitely the one! Spinning is super intense. It's a killer when you first get started, but in no time at all, you'll be such an expert that you'll wonder why you didn't start doing it sooner. It's kind of like cycling, of course, but you work at a much faster pace. It's better to start out slow so you don't get overwhelmed, but if you do it regularly then, over time, you can spin for longer and longer periods of time.
