Caution!! Newbie Question Alert!!!!!

Please utilize your stupid question filters, for your own sanity!




What I need to know is, what is the difference between "spinning", and using one of the indoor set-ups with a "real" bike?

I also need to know if there are major issues I should watch out for if I decide to shop for a training set-up? I have seen things sort of like a treadmill w/rollers, and I have seen tripod-type set-ups, but I don't have a clue as to what is good or bad.

Thanks for your kind indulgence.
