The whole point is to get your heart rate up and push your body as hard as it can go. If your heart isn't banging, your breath isn't panting and your muscles aren't burning, then you aren't going hard enough to accomplish anything worthwhile.
If you can't run, then bike or swim or something.
Walking ain't shit, not at any speed, because it's easy.
Cardio is supposed to be hard, and it's supposed to hurt, because that's how you know that you're pushing your entire body's boundaries. Embrace it.
