Abstract: The disclosure features physical activity devices that include (a) a central footrest, configured to receive at least a portion of a foot of a user, (b) a plurality of elongated sleeves, each sleeve having an inner and an outer surface, and being configured to at least partially enclose an elongated tubular support member, and having spaced grooves in its outer surface extending generally perpendicular to a longitudinal axis of the sleeve, and (c) at least two loops extending from the footrest, the loops being configured to be received by the grooves so that the sleeves support the footrest above a surface on which the tubular support members are positioned. The disclosure also features methods of using such devices.
