Bal-A-Vis-X is a series of some 300 exercises, most of which are done with sand-filled bags and/or racquetballs, often while standing on a Bal-A-Vis-X balance board. Requiring multiple thousands of mid-line crossings in three dimensions, these exercises are steadily rhythmic, with a pronounced auditory foundation, executed at a pace that naturally results from proper physical techniques. Bal-A-Vis-X enables the whole mind-body system to experience the symmetrical flow of a pendulum.
