The GHD Back Extension

The GHD back extension is dissimilar in action to CrossFit’s nine foundational movements. The spine actively and deliberately flexes and extends. While you would not want to flex and extend the spine in such a way while lifting, it is important to develop the strength and positional awareness to move from these positions to a neutral position.
