A few years ago when I was first getting into fitness I took a couple of spin classes - and HATED them! I didn't like the non-stop pedalling although I did admit that it was an excellent cardio work-out. There was something too monotonous about the endless pedalling and the pace was relentlessly fast. I have never taken one since. But today, because I am banned from the treadmill and I really hate the elliptical I forced myself onto the exercise bike at the club. There are two kinds there: the recumbent bike that most people are familiar with when it comes to exercise bikes, and one more like a regular bicycle, which is the one I used. I remembered what we had been told to do in the spin classes I took so long ago and did a 30 minute work-out based on some of those concepts, such as raising the butt in the air and pedalling standing up as well as raising and lowering the butt repeatedly. It was a pretty good work out and I will do it again. There is life after running!
