Video 5-Deadlift Series: Stability Exercises for Hip-Hinge Movements – GHD Back Extensions and Reverse Hypers:
GHD Back Extensions: Face down in the GHD, start with GDH back extension holds. Maintain a neutral pelvis and a neutral neck. Hold up to 60 seconds. After holds, move to eccentric. Move slowly down for 6-8 seconds. Release glutes, maintain stiff back for stability training and initiate the movement up with the glutes. You can eventually add load to the exercise to train stability for the hip hinge movement.
Reverse Hypers:
Squeeze glutes to start the movement. Press hips into the crease of the pad on the reverse hyper. Hips and back stay neutral. You can do eccentric reps and isometric holds here to train stability.
