| 1. A self-regulating endless climbing wall, comprising:
a form including upper and lower at least partially cylindrical outer surfaces, a planar forward surface, and an open back
surface;
a rotating belt having an inner surface and an outer surface, the inner surface being disposed in sliding engagement with
the cylindrical surfaces and planar forward surface of the form, the outer surface of the belt including a plurality of raised
features configured for climbing by a user;
a tensioning shoe that engages with the inner surface of the belt through the open back surface of the form; and
a mechanism, coupled to the tensioning shoe, operative to:
a) relieve tension on the belt as a user climbs upwardly, thereby increasing rotational slippage of the belt around the form,
and
b) increase tension on the belt as a user moves downwardly, thereby reducing or terminating rotational slippage of the belt
around the form.
