Rollers are mainly for warmups - supposedly you can't really get too much of a workout on them because most people can't sustain the concentration needed to stay up on them for an extended period of time. But boy oh boy, do they ever help you smooth out your pedal stroke (IOT smoothly ride on rollers, you have to be very economical with your body's movements, hence you develop a fluidity that translates to the real road).

Cool pic - and a good way to keep away from the long arm of the law after imbibing a few
