The Valor Fitness CB-13 Adjustable Back Extension is a great tool to build lower back muscles as well as strengthening and conditioning the obliques and abdominal muscles. The adjustable back extension (or reverse sit up) can be used with only your body weight or in conjunction with additional weight such as a weight vest or a slam ball. Adding additional weight to your workout helps to increase muscle tone and resistance.
