This was my first-ever Leslie Sansone video, and I was surprised by how tough it was, especially given that I already exercise regularly and have even started a running program in the past month.  Leslie uses four basic moves--march, side step, front kick, and knee lift--but varies the speed and execution of each movement to change the intensity.  In addition, this workout uses Leslie's special weight belt for upper body toning work; I don't own the belt, so I substituted light (3 lb.) hand weights throughout the workout.
