Abstract
A resistance device for providing resistance. The device includes a flexible pulling element, a resilient arrangement and a transmission. The resilient arrangement has a first portion and a second portion. The second portion is resiliently movable relative to the first portion. The transmission connects 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 transmission is a reduction arrangement such that pulling the flexible pulling element a distance moves the second portion, relative to the first portion, no more than a proportion of the distance. The proportion is no more than half.
