The seated back extension machine is a machine that consists of a seat for your butt and a stack of weights which you can load to help you strengthen your lower back. Similar to the hyperextension bench exercise, the seated back extension machine targets the erector spinae muscle groups (iliocostalis, spinalis & longissimus). The back extension machine targets the erector spinae, which are three muscles: illiocostalis lumborum, longissimus thoracis, and the spinalis. This bundle of muscles lies in a groove along the vertebral column.
These muscles extend your lumbar spine. Synergistic muscles used in the back extension are the gluteus maximus, hamstrings, and adductor magnus. Stabilizer muscles used include the back, shoulder and neck muscles: biceps, triceps, lats, deltoids, traps, pecs, and rhomboids.
Being able to isolate the lower back in this way is great as you can really concentrate on the key groups of muscles that help you at the lower end of the spine. My own personal experience from using this machine is that I walk away feeling a lot more stable and stronger in the lower back regions as a result.
