Hi all, Can anyone explain the advantage of using a turbo trainer over the exercise bikes in the gym. I already have a gym membership which I pay for and they have the normal upright and recumbant excercise bikes. I was toying with the idea of getting a turbo trainer for the winter but wonder if there is any real advantage over the gym kit? I am led to believe that with a turbo trainer I have to put towels all over the place as the sweat will rot my bike and that I need to buy a fan to keep cool. This seems a right pain in the arse when compared to jumping in the car and going to the gym which is already air-conditioned and has a little telly to watch on each bike. Is there a specific benefit to a turbo trainer or is just that I'll be training on (and knackering) my own bike? Thanks, Mark.
