ABSTRACT:
The portable flexible exercise device is a quadrilateral with handles at the corners. Compression members extend between the adjacent handles and are pivoted thereto. A tension member is engaged so that one pair of opposite handles is resiliently urged apart while the other pair is resiliently urged together so that the exercise device can be utilized in different forms of exercise.
