Abstract: A removable stretchable cover for exercise equipment has a first wall, a second wall, two side walls and two end walls arranged to form an interior cavity and an opening through which the exercise equipment is appointed to traverse. The opening is formed as a stretchable slit opening adapted to expand to engulf the exercise equipment, and contract in a closed configuration when the exercise equipment is housed within the interior cavity to substantially enclose the equipment within the cover. At least one anti-slip surface is integrated within at least one of the first wall, second wall, two side walls or two end walls. The cover is composed of a thin, stretchy, soft material so that it can be significantly stretched and contracted to snuggly fit over the exercise equipment. Examples of exercise equipment for which the cover is especially well suited include yoga blocks, foam rollers, exercise balls and arm handles of exercise machines.
