How to perform Seated Good Mornings
- Set up a box in a power rack. The pins should be set at an appropriate height. Begin by stepping under the bar and placing it across the back of the shoulders, not on top of your traps. Squeeze your shoulder blades together and rotate your elbows forward, attempting to bend the bar across your shoulders.
- Remove the bar from the rack, creating a tight arch in your lower back. Keep your head facing forward. With your back, shoulders, and core tight, push your knees and butt out and you begin your descent. Sit back with your hips until you are seated on the box. This will be your starting position.
- Keeping the bar tight, bend forward at the hips as much as possible. If you set the pins to what would be parallel, you not only have a safety if you fail, but know when to stop.
- Pause just above the pins and reverse the motion until your torso it upright.
Muscles worked
- Hamstrings (primary): bends the knee and extends the hip through hinges and pulls.
- Glutes (secondary): extends and stabilises the hip — the engine behind hinges, squats and sprints.
- Core (secondary): braces the trunk and resists twisting to protect the spine.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Lead with the hips, keep a soft knee and hold a long, flat back through the hinge.
- Keep the bar path close and stacked over your mid-foot; letting it drift forward wastes force and loads the lower back.
- Rehearse your setup identically on every rep; dependable strength is built on one groove you can trust.
- Stop a rep or two short of failure on most sets to keep form clean and recover faster.
Common mistakes
- Rounding the lower back to reach lower instead of hinging at the hips.
- Loading the bar heavier than your form allows and turning strict reps into a whole-body heave.
- Changing your setup rep to rep so the groove never becomes automatic.
