Barbell Seated Good Morning
What Is the Barbell Seated Good Morning?
Barbell Seated Good Morning is a compound exercise that primarily targets the back, specifically the spinal erectors, and also engages the glutes, hamstrings and adductor magnus. It is an advanced-level movement that asks for a strong brace and steady control of a flat back while a loaded barbell sits across the shoulders.
The movement is a hip hinge performed from a seated straddle on a flat bench. With the bar on your upper back, your torso becomes a long lever as you lean forward, and the spinal erectors work mostly isometrically to hold the spine still while the hips flex and extend beneath it. Because the knees stay bent at about 90 degrees, the hamstrings are slack at the knee and lengthen far less than they do in the standing Barbell Good Morning. Hamstring flexibility rarely limits how far you can lean, and the spinal erectors take a larger share of the work, while the glutes still drive the torso back to upright.
The seated good morning is a long-standing staple in Westside-style powerlifting training, where it is used as a main movement for heavy low-rep sets or as an accessory for moderate and higher reps to build the back and trunk strength that supports the squat and deadlift. It usually sits after the main lift of a lower-body or back session. Specialty bars change the feel: a safety squat bar or cambered bar moves the load and the hand position, and lifters rotate between them to vary the stress on the upper and lower back.
It suits lifters who already own a clean hinge in the Barbell Romanian Deadlift or the standing good morning and want more direct back work, and lifters whose hamstring flexibility cuts the standing version short. It is not the best choice for building the hamstrings themselves, so pair it with a straight-leg hinge or the Machine Lying Leg Curl when that is the goal. If a loaded bar on your back is too much for now, build up with the Hyperextension and an unloaded seated hinge before adding weight.

Instructions
- Place a flat bench lengthwise inside a power rack, set the bar on the hooks at about shoulder height when you are seated, and set the safety pins low enough to clear your lowest rep but high enough to catch the bar.
- Straddle the bench near its end with your feet flat on the floor, wider than your hips, and your knees bent about 90 degrees.
- Take an overhand grip just outside your shoulders, set the bar high on your upper back, and pull it down into your traps with your elbows pointing down.
- Sit tall to lift the bar off the hooks, with your chest up, your neck in line with your torso and your eyes on the floor a few feet ahead.
- Take a full breath and brace your abdominals.
- Hinge forward from the hips, tipping your pelvis forward on the bench while your back stays flat and the bar stays pinned to your upper back.
- Lean only as far as you can keep your lower back flat, then pause briefly.
- Squeeze your glutes and drive your torso back to upright along the same path, exhaling as you near the top.
- Repeat for the planned reps, then sit tall and return the bar to the hooks.
Common Mistakes
Rounding the lower back
Letting the lower back curve to get lower turns the hinge into loaded spinal flexion under a heavy bar, which is the main source of back strain in this lift.
Leaning past a flat back
Chasing a deeper lean after the pelvis has stopped tilting forward only comes from the spine bending, so the rep should end where the back is still flat.
Loose brace
Starting the descent without a full breath and tight abdominals lets the torso sag under the bar and leaves the lower back to hold the load alone.
Bar sliding onto the neck
Not pulling the bar down into the upper back lets it roll up toward the neck as you lean, which presses on the cervical spine and makes the bar harder to control.
Cranking the head up
Looking up at the ceiling throughout the lean overextends the neck, so keep the neck in line with the torso and your eyes on the floor ahead.
Too much weight too soon
Loading the bar like a squat outpaces what the spinal erectors can hold flat, so the form breaks down before the hips are challenged.
Injuries
Barbell Seated Good Morning is a medium risk exercise when performed with proper technique. At the bottom of each rep the bar sits well in front of your hips, so the lower back has to resist a large bending force. The lumbar spine is the main strain point, particularly when the lower back rounds under a heavy bar. The neck and shoulders can also complain if the bar rides too high or the grip is too narrow for your shoulder mobility.
Keep the load modest and progress it slowly, since the spinal erectors tire long before the hips do. Brace before every rep, keep the bar pinned to your upper back, and stop each descent where your lower back is still flat rather than chasing a deeper lean. Set up inside a power rack with the safety pins set to catch the bar, so a rep you cannot finish can be set down instead of dumped.
To regress, practice the seated hinge with no weight or a light dowel along your spine, and build back endurance with the Hyperextension or Bird Dog. To progress, add load gradually, add a pause at the bottom, or move to the standing Barbell Good Morning once your hamstring flexibility allows a flat back there.
Stop the set if you feel sharp pain in your lower back, pain that travels into your buttock or leg, or numbness or tingling in your legs. Pain that lingers after training also means it is time to drop the exercise and have it assessed before loading it again.
Frequently Asked Questions
- Q: Does the seated good morning work the hamstrings?
Somewhat, but much less than the standing version. With the knees bent about 90 degrees the hamstrings are slack at the knee, so the spinal erectors and glutes carry more of the work; for hamstrings, choose the Barbell Good Morning or Barbell Romanian Deadlift.
- Q: How far forward should I lean?
Lean only as far as you can keep your lower back flat. Since tight hamstrings no longer stop you, your hip mobility and back control set the depth, and a shorter rep with a flat back is always the better rep.
- Q: How heavy should I go?
Start with the empty bar for sets of 8 to 12 reps and add weight only while every rep keeps a flat back. Expect to use far less than you squat, since the lower back has to hold the bar out in front of the hips.
- Q: Do I need a rack for seated good mornings?
A power rack is the safest setup. Put the bench inside the rack, set the bar on the hooks at about shoulder height when you are seated, and set the safety pins so they catch the bar if you lose a rep.
- Q: Can I use a safety squat bar or cambered bar?
Yes, and many powerlifters do. The safety squat bar's handles take strain off the shoulders, and rotating between bars changes where the load sits, which shifts the emphasis between the upper and lower back.
