Walking in Place

Today I used Leslie Sansone's Walk at Home - 5 Mile Fat Burning Walk. I did the first two miles and worked up a good sweat, at a 5 mph pace, holding a 3.3 pound weight in each hand. I've never been one to do group aerobics. The idea of doing this in a place surrounded by mirrors so that I can see just how ridiculous I look is completely unappealing.
