DisclosureAI-generated illustration: the face is based on the site owner's own photos; the body, equipment and background are generated and do not represent his real physique or training records. Tool: built-in image_gen.
Frames were checked by a professional reviewer for movement; follow the written steps and qualified coaching. The image does not depict a real physique or training record.
Steps
- 01
Set the 45-degree extension bench so the hips can hinge freely above the pad and secure the feet on the platform.
- 02
Rest the hands across the chest, brace lightly and keep the head, back and pelvis aligned.
- 03
Hinge forward at the hips and lower the torso within a controlled range without excessive rounding.
- 04
Use the glutes and hamstrings to return until trunk and legs are roughly in line, without hyperextending backward.
Common mistakes
- Placing the pad over the hip hinge and repeatedly swinging through the lower back.
- Hyperextending past body alignment or bouncing through the movement.
