The Keiser Air250 Lower Back is an essential and complimentary companion to the Air250 Abdominal machine. It works to strengthen the critical erector spinae muscles of the back, the site of most back problems. Keiser engineers have created a machine with easy access; keeping adjustment to a minimum. The seat belt comfortably secures the pelvis in the correct position.
