The good morning: proper technique, common mistakes, and who it's for

How to perform the barbell good morning correctly, what weight and rep ranges actually make sense, which mistakes overload your lower back, and when to skip it.

The good morning is a hip hinge with a barbell sitting on your upper back — it looks like a deep bow and works like a deadlift, except the load sits far away from your hips. On paper it is simple; in practice it is the exercise where the difference between bending at the hip and bending at the spine shows up fastest. Here is how to do it, what people get wrong, and who actually needs it in a program.

What the good morning actually trains

The hamstrings and glutes do the main work — they extend the hip as you come back up. The spinal erectors work isometrically: their job is to keep your back in exactly the same position from the first inch to the last, not to round and then straighten. If your back position changes during the set, the exercise has missed its point.

Unlike a Romanian deadlift, where the load is in your hands and close to your body, here the bar is on your back and the lever is longer. Expect to use noticeably less weight — realistically 30–50 percent of your Romanian deadlift — while the load per kilo on the bar sitting on your lower back is higher.

Technique, step by step

Set the bar like a low-bar squat: on the rear delts, roughly 2–3 cm below the top of the traps. If it digs into bone, it is too high.
Feet hip- to shoulder-width, toes turned slightly out. Knees unlocked and bent about 10–15 degrees — and they stay there the whole time.
Breathe into your stomach, brace your abs like you are about to take a punch, pull your shoulder blades together. The bar should sit on muscle, not slide.
Push your hips backward, as if closing a car door with your backside. Your torso lowers because the hips travel back, not because you fold forward.
Descend while you feel a stretch in the hamstrings and while you can hold your back flat. For most people that lands somewhere between 45 degrees and parallel to the floor. Depth is not the goal.
Come back by driving the hips forward and squeezing the glutes. Exhale at the top. Do not push your pelvis forward past your body line.

Tempo: 2–3 seconds down, no pause at the bottom, about 1 second up. Dropping too fast is the single most common reason people lose back position around rep five.

The most common mistakes

Rounding the back instead of hinging

If your upper back rounds and the bar starts creeping toward your neck, that is no longer a good morning — it is a back lift. Fix it by taking 30–40 percent off the bar, filming a set from the side, and comparing your first and last rep.

Knees drifting forward

When the knees bend during the movement, the lift turns into a bad squat and the hamstrings drop out. The knee angle stays identical from the first rep to the last.

Chasing depth

Going below the point where your pelvis starts to tuck under loads the lower back with no extra benefit for the muscles. Sixty degrees with a flat back beats parallel with a rounded one.

Too much weight

This is not a personal-record lift. If you cannot get 8 clean reps, the bar is too heavy — there is no middle ground here.

Holding your breath through the whole set

On sets of 10 or more, breathe between reps at the top of the movement. Long straining with held breath in a bent-over position raises blood pressure more than it needs to.

Weight, sets, and where it belongs in a program

First 2 weeks: empty barbell (20 kg) or even a broomstick, 2–3 sets of 10–12 reps, technique only.
Working range: 3 sets of 8–12 reps, 90–120 seconds of rest.
Intensity: leave 3–4 reps in reserve. Your last rep should look like your first.
Practical ceiling for most people: 40–50 percent of your squat. If you squat 100 kg, a 40–50 kg good morning is already serious.
Progression: +2.5 kg every 1–2 weeks, but only while technique holds.
Frequency: 1–2 times per week, always after your main lift (squat, deadlift), never before it.

Who it suits, and who should wait

It makes sense if your torso pitches forward in the squat, if your hamstrings clearly lag behind your quads, or if you train powerlifting or a sport with a lot of sprinting and jumping. It is also useful if you want to build the ability to hold a flat back under load, because that is literally the whole point of the lift.

Skip it for now if you have been training less than 6 months and do not yet own a clean hinge in the Romanian deadlift, if you currently have lower back pain, if your shoulder or wrist cannot hold the bar stable on your back, or if you are pregnant and training without qualified supervision. Substitutes with a similar effect and less risk: Romanian deadlifts, 45-degree back extensions, hip thrusts, and back extensions with a 2-second pause at the top.

When to see a doctor

Pain radiating down the leg, tingling, or a feeling of weakness in the foot.
Back pain that does not ease within 7–10 days, or gets worse day by day.
Pain at night and at rest, especially with fever or unexplained weight loss.
Trouble controlling urination or bowels plus numbness around the groin — that is same-day urgent.
Known high blood pressure, heart disease, or recent surgery — check before adding heavy straining lifts.

The short version

Hips go back, knee angle stays fixed, back position does not change from the first rep to the last.
Start with an empty 20 kg bar for two weeks, then 3 sets of 8–12 reps with 3–4 reps in reserve.
For most lifters, 40–50 percent of your squat is the realistic upper limit.
Lower for 2–3 seconds and stop when your back starts to give, not when you hit parallel.
Leg pain, tingling, or foot weakness means stop and get checked — not just lighter weight.
