Easy back strengthener without props. This will lengthen and strengthen the muscles of the entire backside! Great if you are working on changing a kyphosis in the upper back.. yes, most of us who have sat in front of a computer for any length of time have this.. and we all can change it. Did I mention that I gained an inch by working on back strength and mobility when I started to research functional fitness after 5 years at a desk? You can do it!
