I travel quite a bit now, and I always take my Powerfits, and SI6/Burn it up and Keep it Up. The reason I like these so well, is because when using a laptop, it is akward if you are doing a workout that requires a lot of floorwork. In the SI6 workouts, the floorwork is all at the end. The Powerfits do not have a lot of floorwork. They are all low impact, so they are quiet. Usually, I do them very early in the am, and DH is asleep just a few feet from where I am doing my workout. Oh, also Leslie workouts are good, but if you are doing a lot of walking you probably don't need those.
