Abstract: A resistance apparatus for use with exercise devices includes an axle and outer housing for rotatably mounting the axle therein. At least one inner housing includes an opening for receiving the axle therethrough so that the inner housing is fixably mounted on the axle. The inner housing is rotatably mounted inside the outer housing to permit rotation of the inner housing along with the axle within the outer housing. At least a first tensioned member is disposed within the inner housing. The first tensioned member includes a first end and a second end. The first end of the tensioned member engages an engagement area of the inner housing. The second end of the tensioned member engages an engagement area of the outer housing. The tensioned member creates a rotational restoring force between the inner housing and the outer housing.

Abstract: Disclosed is a foldable exercise device comprising a seat with a front and rear portion. The front portion is pivotably attached to at least one support member. The rear portion includes an intermediate pivotably lateral support member attached between first and second vertical support members. Each of the first and second vertical support members includes top and bottom ends. The seat is configured to pivot to at least two positions including an open position and a folded position. A back support is pivotably secured to the intermediate pivotable lateral support member. The back support is configured to pivot to at least two positions including an open position and a folded position. A resistance apparatus is secured between the first and second vertical support members. The resistance apparatus is configured to supply a variable resistive force when at least one connector coupled to the resistance apparatus is pulled by a user.
