Ever been to a spin class? The students aren't all aerobics instructors like in the videos...
Nothing bad about people wanting to work out, but many of them aren't cyclists and may be harder on the gear than someone with a developed spin. If you're already experiencing breakage, you may want to take the parts to an LBS and see what they would recommend would hold up better. For instance, if they come equipped with cheap cup and cone BBs, you may want to use a better grade of cartridge type.
