  • Athletic stretching device
    Patent number: 6705974
    Abstract: A stretching device for stretching and strengthening the muscles of the lower back and legs of the user. The stretching device generally includes an attachment bracket, pull cord and pulley. The attachment bracket attaches to the top of a door frame and the pull cord and pulley are attached to the attachment bracket. The pull cord engages the pulley so that a sling is formed on one side of the pulley. A user inserts their leg into the sling and raises and lowers the sling causing muscles in the legs and back to stretch. Several stretching routines are possible which isolate and target certain muscle groups.
