1. A resistance device, for providing a resistance, the resistance device comprising:
a flexible pulling element;
a resilient arrangement; and
a transmission;
the resilient arrangement having a first portion and a second portion, the second portion being resiliently movable relative to the first portion;
the transmission connecting the flexible pulling element to the resilient arrangement such that pulling upon the flexible pulling element moves the second portion relative to the first portion, and upon release of the flexible pulling element the resilient arrangement retracts the flexible pulling element;
the resilient arrangement including a plurality of resilient elements, at least one of the resilient elements being a selectable element;
the resistance device including a selector mechanism by which at least one of the selectable element(s) is selectively engageable to vary the resistance;
the selector mechanism including a selector member carried by the second portion, the selector member being movable:
to engage the selectable element(s) such that the selector member abuts the or each selectable element to resist movement of the flexible pulling element, and
to disengage the or each selectable element so as to enable the second portion to move along the or each selectable element,
wherein the selector member includes a plate having a blocking portion, which acts on the selectable element to resist withdrawal of the flexible pulling element, and one or more apertures, which allow deselected resilient elements to bypass the plate.
