Patent ID: 8152703

Claim:
An exercise device for providing lift assistance including: a) an elastic resistance unit suspended from an elevated support via an upper attachment, the elastic resistance unit having a resistance unit top connector and a resistance unit bottom connector, wherein: 1) the upper attachment: (i) is adjustable such that the distance between the elevated support and the resistance unit top connector can be changed; and (ii) includes: (a) a hook extending from a cam buckle, (1) the cam buckle having two constricting surfaces spring-biased toward each other, (2) the hook being suspended from the elevated support; and (b) a connecting strap adjustably extending between the constricting surfaces of the cam buckle, the connecting strap connected to opposing sides of the resistance unit top connector; 2) the resistance unit top and bottom connectors each have one or more elastic member sockets, (i) each elastic member socket having a socket slot opening onto a socket passage, (ii) each socket passage extending between top and bottom surfaces of the resistance unit top and bottom connectors; and 3) the elastic resistance unit is configured to removably receive one or more elastic members between corresponding elastic member sockets of the resistance unit top and bottom connectors, wherein receivable elastic members: (i) have an elastic elongated portion between two member plugs, the member plugs being configured to resist passing through the socket passages of the elastic member sockets; and (ii) are installable in the elastic resistance unit by having a portion of each member plug thereof inserted within corresponding elastic member sockets; and b) a lower loop descending from the resistance unit bottom connector of the elastic resistance unit, the lower loop having an opening sized to receive at least a user's foot.
