Yet another kind of equipment!
Slide workouts became popular a few years ago. Using a slippery floor mat with "stops" at each end, and special shoes, you move from side to side in a motion similar to a speed-skater (I've never done it, so I'm just describing what I assume it looks like.) Presumably, there are a variety of arm and log movements to increase intensity and work different parts of the body. I can't find any tapes in the Collage catalog I have at hand, but I think there are technique tapes available. You might look for a Slide class at a local gym or fitness center if you want to try it.
