45 Degrees Back Extension
Description
The 45-degree back extension performs back extensions on a dedicated 45-degree hyperextension bench. You lower your torso forward by hinging at the hips, then extend back up. The 45-degree angle provides a different resistance profile than flat or horizontal back extensions.
