This video is a progression of a slow motion marching drill with reciprocal arm swing that Bruce Wilk first introduced to me in static single leg balance. I like to move, however, so I advanced it to a slow march. This is a great drill to challenge one's postural stability in single leg balance and is a great drill for long course runners and triathletes who are prone to form breakdown in the latter stages of a race.
