If you're curious how DDR works for exercise purposes, here is a sample set list of what I'll do for about an hour of exercise, using DDR Extreme, DDRMax2, DDR Supernova 2 and DDRX on my PS2.

Note that I am certainly not a DDR Expert! I am an average, every day woman who is 135 pounds at 5'7". I don't run marathons and am not in top physical shape. This is a nice workout to keep me toned and my balance solid. These are aims that all of us should have, regardless of our age.

Many of the songs, especially the intro ones, I can nail on "perfect" but I include them in this order so my muscles can warm up gradually. You want to ease into the faster workouts so that your muscles can be warm before you take them on.

I have a setup in my basement with a cheap monitor, the PS2 and dance pad, and a foam "floor block" beneath the pad to cushion my dancing. It's one of those interlocking types you find in hardware stores to put on basement floors. I dance in socks.
