Good mornings: technique, common mistakes and safe loading

How to set up and perform the good morning, how much weight is enough, which mistakes cost you most, and what to use if you have no rack.

Watch someone bend forward under a loaded barbell until their torso is nearly parallel to the floor and the same thought tends to surface: surely that is asking for a back injury. It is a fair worry, and the answer comes down to two things — how much weight is on the bar and how controlled the descent is.

Most people who do good mornings badly do so because they treat it as a strength lift. It works far better as a control and endurance lift. Here is the practical version: what it trains, how to set it up, where it usually goes wrong, and what to do instead if you have no barbell or rack.

What the exercise is and which muscles it works

A good morning is a hip hinge performed with a barbell resting across the upper back, in the same position you would use for a squat. The knees stay slightly bent and essentially still, the hips travel backwards, and the torso lowers forward while the spine holds a neutral position throughout.

The hamstrings and glutes do the bulk of the work, lengthening on the way down and driving the torso back up. The adductor magnus assists at the hip, while the spinal erectors work isometrically — they do not shorten, they simply fight to keep the back flat as the lever gets longer.

That lever is the key difference from a Romanian deadlift. In an RDL the load hangs close to the hips; in a good morning it sits on your back, much further from the hinge point. The weight is therefore far lower. Somebody who handles 100 kg for RDLs might work hard with 40 kg here, and that is simply mechanics rather than weakness.

The lift earns its place for two reasons. It teaches you to separate hip movement from spinal flexion, which carries straight over into squats and deadlifts, and it loads the lower back in an endurance-style way — one of the few things that genuinely helps when it comes to keeping low back pain at bay.

How to perform it

Set the bar in a rack at upper chest height and, if the rack has them, drop the safety pins to roughly lower chest height.
Step under the bar and place it across the upper back. Sitting it slightly low, across the rear delts and the shelf of the traps, is usually more comfortable than high on the neck and shortens the lever a little.
Squeeze the shoulder blades together, grip the bar firmly, and walk it out in two or three steps. Feet hip width or slightly wider, toes turned out a touch.
Breathe into your stomach and brace the trunk as though you were about to take a punch. Hold that brace for the whole rep.
Push the hips backwards and let the knees bend to about 15 degrees. They stay there — no further bending.
Lower the torso slowly, over two to three seconds, feeling the hamstrings stretch.
Stop just before the lower back starts to round. For most people that lands somewhere between 45 degrees and parallel, and that range is plenty.
Come back up by driving the hips forward and squeezing the glutes. Finish standing tall, without shoving the hips through and arching backwards.
Breathe out, reset the brace and repeat. Rack the bar at the end of the set — a good morning is never lowered to the floor.

Common mistakes

Too much weight. By far the most common error, and the root of every other one on this list. If you cannot keep a flat back for all ten reps, the load is wrong, not the exercise.
Going too deep. Depth is not the goal. Once the pelvis tucks and the lumbar spine rounds, load shifts from muscle onto passive structures. Film yourself from the side to find your actual limit.
Turning it into a squat. If the knees drift forward as you descend, the hips stop doing the work and the hamstrings never lengthen.
Bar too high on the neck. It is uncomfortable, pushes the head forward, and lengthens the lever. Drop it a few centimetres.
Cranking the neck up. Staring at the ceiling does nothing for your back. Look at the floor a few metres ahead so the neck follows the line of the torso.
Losing the brace. Exhaling completely at the bottom leaves the spine unsupported exactly where support matters most.

Easier variations

For the first couple of weeks, do the movement with no load at all — arms crossed over the chest, or a broomstick across the back. The point is to find the depth at which your back starts to round before any weight is involved.

A resistance band looped over the upper back and pinned under both feet adds a little tension, and usefully the tension increases as you descend, which forces you to finish the rep standing tall.

The seated good morning, performed on the end of a bench, is a good option if your pelvis keeps tucking. Sitting reduces the hamstring contribution and puts most of the work on the erectors, over a shorter and more forgiving range.

And the simplest fix of all: shorten the range. Stopping at 45 degrees with a spotless spine beats hitting parallel with a rounded one.

Harder variations

A two-second pause at the bottom removes any bounce and tests whether you really own the position.
A slower eccentric, around four seconds down, adds time under tension at the same weight.
Straighter knees. The flatter the knees, the longer the hamstrings and the harder the lift. The weight has to come down accordingly.
A wide stance with toes out brings the adductors in more and suits many hip structures better.
A safety squat bar, if your gym has one. It is kinder on the shoulders and makes it easier to keep the upper back upright.

Alternatives if you have no equipment

Without a rack and barbell, the same hinge pattern is trainable with dumbbells or a kettlebell through Romanian deadlifts. The load sits in front of the body, the lever is shorter, and the hamstrings feel almost the same thing.

With no equipment at all, back extensions on a 45-degree bench and eccentric-only Nordic curls — lowering slowly and catching yourself with your hands — cover most of the ground. For the glutes specifically, hip thrusts and single-leg bridges do the job.

One clarification worth making: the good morning is not an upper back mass builder. If that is what you are after, you want rowing, something like the T-bar row, with good mornings kept as accessory work for the hips and lower back endurance.

Sets and reps

Three sets of 8 to 12 reps, once or twice a week, covers most people. Stop each set with two or three reps in reserve; training to failure makes little sense here, because technique breaks down before the muscle does.

If you are new to it, spend three weeks doing 2 to 3 sets of 10 with an empty 20 kg bar, or even just a stick. Only then start adding weight, in 2.5 kg steps, and only when every rep looks clean.

Training for strength, 3 to 4 sets of 5 or 6 with a heavier bar works well, though still well short of maximal. Place the lift after your main work, never before heavy squats or deadlifts — tired erectors ruin everything that follows.

Expect slow progress. Adding 10 kg to your good morning over several months is a perfectly normal rate.

Who it suits, and when to avoid it

The people who gain most are those whose backs round in the deadlift, those who fold forward out of the bottom of a squat, and athletes who sprint or kick, since the hamstrings there work in exactly this lengthened position.

Age is no barrier. With lighter loads and a shorter range, this stays useful past fifty as part of a more sensible approach to training at that age, where the aim is holding onto hip strength without taking on pointless risk.

Skip it, or at least swap it for an easier version, if you currently have low back pain that worsens when you bend forward, if you have had recent spinal or abdominal surgery, or if your shoulders and upper back will not let you hold a bar comfortably. The seated variation and back extensions give you much of the benefit with less to go wrong.

When to see a doctor

Ordinary muscle soreness after training settles within a day or two. See a doctor if back pain radiates down the leg, if you notice numbness or weakness in the foot, if pain wakes you at night, if it followed a fall or a blow, or if it has dragged on for more than four to six weeks without improving. Loss of bladder or bowel control alongside back pain needs urgent medical assessment the same day.

In short

The good morning is a hip hinge with a bar on the back; it trains the hamstrings, glutes and lower back endurance.
The weight is much lighter than in a deadlift because the lever is longer — that is expected.
Lower only to the point just before the back rounds, not to parallel at any cost.
Three sets of 8 to 12 reps, once or twice a week, always after your main lift.
If bending forward hurts your lower back, start with the seated version or back extensions instead.
