Try riding on a stationary bike, and keeping your revs at 80-100. To increase your "intensity" increase the resistance on the bike, not your revolutions. The 1-10 scale is really the most effective way to go where 10 being a resistance you can only maintain a short time (1-2 minutes max) and 1 being a leisurely pace.

If your interval goes 9-3-9-3-9-3 then go from 9 resistance to 3. If you are in great shape then maybe you would do 18 for intense and 6 for slow, you sort of have to gauge it. Try one workout at the baseline resistances and see how it works you.

Heart rate is not really effective because someone in bad shape will have their heart-rate rise very quickly and lower very slowly, and their heart rate is probably on the high end doing heavy exertion activity like intervals. Whereas someone in great shape will have their heart rate drop much faster during rest and most likely won't be as high during the most intense work. I would stick to the 1-10 scale.
