Abstract: A friction-stabilized back and shoulder stretch bar to facilitate a plurality of stretches, including “kitchen sink stretches” to prevent and treat conditions such as neck and back pain. In use, the friction-stabilized back and shoulder stretch bar is not mounted to a door frame, but instead includes two friction-based stabilizers for use with door frames and entryways. The stretch bar can be made in lengths to fit within standard door frame widths, or can be made to be length-adjustable. The friction-based stabilizers are at opposite ends of a handlebar of the stretch bar, the handlebar having gripping regions or grips that can be: cushioned vertical grips with finger grooves, custom grip attachments, and/or handlebar curvature gripping areas with neutral wrist placement. The handlebar can be made from structurally reinforced plastic, and can have custom over molding or a covering and/or padding made from one or more resilient materials.
