I am designing a new kind of spinning bike. i have been in the fitness industry for 30 years and am checking out comments on the net to see what people are experiencing and any problems they have from taking spinning classes. i have been working on this project for 3 years and will introduce the product to the market in march at a trade show called IHRSA. This is not a commercial message i just want to make disclosure so no one misunderstands.

i think you pain was caused not only from the intensity of the ride, because you would have recovered quicker than you did, but instead from the biomechanics of the normal spinning bike. your real road bike moves under you and allows your body to follow natural paths, but the spinning bike stays still and forces your body into unnatural positions. if you spin enough your body will adapt, but it still isn't good. Check out a cyclist while he or she is riding and then look at a person taking a spinning class. the two bodies will move much differently.
