Hyper Extension

It requires you to face the floor with your thighs on the pad, letting your spine extend upward. Also known as a hyperextension bench, this equipment comes in two versions: 45 degrees and 90 degrees. The 90-degree version is also called a Roman chair.Using a hyperextension bench, you can build strength and tone in your abdominals, glutes, lower-back muscles and obliques. Hyperextension benches can vary, but they either place you in fully prone or supine position or at a 45- to 60-degree incline.
