This stretching aid safely loosens the back, shoulders, and core while sitting. Simply rest the padded base across the lap and reach the arms overhead to grip the top handlebars. Like a physical therapist monitoring an exercise routine, the adjustable stretcher ensures proper spinal alignment while following the 15 seated exercises illustrated in the included booklet. The stretcher swivels and rotates to facilitate safe bending, twisting, and leaning and helps ease low-back pain caused by tight hamstrings and loosen tight shoulders caused by desk work. The lightweight, collapsible stretcher can be packed into a suitcase to alleviate strain experienced during travel. It extends to 10 different heights. 27" L x 6" W x 4" D. (3 lbs.)
