@deltabolic: Hyperextension: Glutes vs. Lower Back 1. To emphasize the lower back: Keep your spine relatively straight and hinge at the hips throughout the movement. 2. To emphasize the glutes: Slightly round your upper back, turn your feet outward, and focus on squeezing your glutes as you extend your hips. 3. Avoid overextending: Stop when your body reaches a straight line. Hyperextending your lower back at the top can place unnecessary stress on the lumbar spine.
