Abstract: An adjustable height balance beam includes an elongate member; opposing upper and lower support columns; opposing base bars; wherein opposing attachment zones of the elongate member are configured for selective attachment to each of the opposing upper support columns, defining a first configuration, and wherein each of the opposing lower support columns is configured for attachment to the corresponding opposing base bars, and the respective opposing base bars, defining a second configuration, for selective height adjustment of the elongate bar relative to the opposing base bars; wherein the height of the elongate bar relative to the opposing base bars may be selectively adjusted when in the first configuration by aligning tension knob ports on the lower support column with a correspondingly selected one of the plurality of linearly displaced apertures on the upper support column to form an aligned attachment channel that is configured for receipt of the tension knob.
