“Why do we use this if the best way to train your core and develop midline stabilization is through the nine foundational movements and other functional movements such as Olympic lifts? Then why this machine?” Josh Everett asks at a Level 1 Seminar. In this video, he answers why and how we train using the glute-ham developer (GHD).
Everett says some of the reasons we use the GHD include creating kinesthetic awareness and body control and introducing training with no load. Everett explains our mantra for CrossFit is “mechanics, consistency and then intensity,” and the GHD is useful for developing mechanics before introducing loads and speed with the nine foundational movements.
“The ability to train and develop under no load (is) crucial in the beginning and can be used throughout an athlete’s career,” he says.
Everett goes over the proper form for GHD movements including the hip extension, back extension, hip-and-back extension and GHD sit-up. Fellow HQ trainer Nadia Shatila demonstrates each movement.
