An exercise apparatus and method allows a user to perform exercises while seated or otherwise supported. Such exercises can assist in avoiding DVT and help those who otherwise might have difficulty exercising due to various conditions. The apparatus requires a base element formed of substantially flat sheet material dimensioned to accommodate a portion of a user's foot, and a leash element attached to a periphery of the base element and dimensioned for retention of the base element. The sheet material reduces friction between a user's foot and the exercise surface to allow a user to exercise their lower extremities via a sliding motion. The leash element allows the base element to be deployed to a floor or other surface for use, and then retrieved without requiring the user to bend over. The leash element is preferably formed of elastic to allow resistive forces to be applied to the base element.
