No, it’s not an extra feature for the GHD. I’m talking about the exercises you can do on it: the hip extension, back extension and hip & back extension. There’s a little bit of confusion about those three movements, so here’s a couple of videos to give you a good idea of the difference. The first one is classic, old-school CrossFit video (I apologize for the music, the video would be great without it) that shows the difference between all three movements.
The second video is Josh Everett explaining the movements and their purpose at a Level 1 seminar.
Recap: Hip extension = hip free of the pad, back stays flat. Back extension = hip on the pad, back does the snakey thing. Hip & back extension = hip free of the pad, back does the snakey thing.
