The good morning is a barbell exercise where you hinge forward at the hips with a bar across your upper back, then stand back up. It targets the entire backside of your body, primarily the hamstrings, glutes, and the muscles running along your spine. The name comes from the movement’s resemblance to bowing in greeting. It’s a staple in strength training programs, particularly for building a stronger squat and deadlift.
Muscles the Good Morning Works
The good morning hits three primary muscle groups: the hamstrings (back of the thigh), the glutes, and the erector spinae (the muscles that run alongside your spine and keep your back straight). Your core also works throughout the movement to stabilize your torso against the load.
This combination makes the good morning one of the more efficient exercises for the “posterior chain,” which is the collective term for all the muscles along the back of your body from your calves to your upper back. A weak posterior chain is often the limiting factor in squats, deadlifts, and athletic movements like sprinting and jumping, which is why the good morning shows up so often in powerlifting and sports performance programs.
How to Perform the Good Morning
Stand with your feet shoulder-width apart and a barbell resting across your upper back, sitting on the meaty part of your traps near your shoulders. Keep your knees slightly bent. Brace your core and take a breath in.
From here, push your hips straight back while your upper body tips forward. Think of it like shutting a car door with your butt, or as if someone tied a rope around your hips and is pulling them backward. Keep hinging until your torso is roughly parallel with the floor, then drive your hips forward to stand back up.
The key distinction is that this is a hip movement, not a back movement. Your spine should stay in the same neutral position throughout. You’re folding at the hips like a hinge on a door, not rounding your back to reach toward the floor. As you work up to heavier weights, bending your knees a bit more will deepen the hamstring stretch, protect your lower back, and let you handle more load safely.
Good Morning vs. Stiff-Leg Deadlift
The good morning and the stiff-leg deadlift are close cousins. Both are hip hinges that load the hamstrings, glutes, and lower back. The main difference is where the weight sits: on your back for the good morning, in your hands for the stiff-leg deadlift.
That distinction matters more than it sounds. Holding a heavy barbell in your hands taxes your grip and puts more demand on your nervous system, which means stiff-leg deadlifts tend to accumulate more overall fatigue. Good mornings let you isolate the posterior chain with lighter absolute loads. Many lifters find they pull over 500 pounds on a deadlift but use only 155 pounds or so on good mornings, making the movement easier to recover from while still getting a strong training effect.
The two exercises also emphasize slightly different areas. Stiff-leg deadlifts tend to stretch the lower portion of the hamstrings more and have a slight edge for improving deadlift strength directly. Good mornings hit the glutes harder and carry over better to squat strength. If you’re choosing between them, stiff-leg deadlifts are more straightforward to load heavy, but good mornings are a useful complement, especially on days when you want less systemic fatigue.
Standing vs. Seated Variations
The standing good morning is the standard version and works the entire posterior chain from your hamstrings up through your back. The seated version, performed on a bench with the bar still across your back, shifts the focus almost entirely to the upper posterior chain: the spinal erectors, upper back, lats, and the muscles between your shoulder blades.
Because your legs are taken out of the equation when seated, your back muscles have to do all the work. This makes the seated version more demanding on your trunk and more punishing if your form breaks down. With the standing version, your hamstrings and glutes can compensate if your technique gets sloppy. Seated, there’s no bailout. Racking the barbell after a seated set is also trickier, so this variation is better suited to experienced lifters who already have a strong base of core and back strength.
How to Program Good Mornings
How you program the good morning depends on its role in your training. As a main exercise (the heaviest lift of the day), working up to a top set of 3 to 5 repetitions is standard. This is common in powerlifting programs where the good morning serves as a max-effort movement to build raw posterior chain strength.
As an accessory exercise, which is how most people will use it, 3 to 5 sets of 5 to 10 reps works well. If you’re using the heavier end of that range (sets of 5), treat it as your primary accessory movement and give it focused effort. At the lighter end (sets of 8 to 10), it functions more as a muscle-building exercise that you can pair with other work without burning out.
Starting Out as a Beginner
The good morning has a reputation as a risky exercise, but that reputation comes mostly from people loading it too heavy too soon. The hip hinge pattern itself is one of the most fundamental human movements. If you can bend over to pick something up off the floor, you already do a version of this daily.
Start by practicing the hip hinge with no weight at all. Stand a few inches from a wall, feet shoulder-width apart, and push your hips back until your butt touches the wall. That’s the movement. Once that feels natural, try it with your hands behind your head to mimic the bar position. From there, progress to an empty barbell, then add weight gradually over weeks.
Research on the good morning’s mechanics shows that even when people try to keep their spine perfectly still, some movement does occur in the lower back under load. This isn’t necessarily dangerous, but it means that core bracing and a neutral spine are skills you need to develop before adding significant weight. Treat the first several weeks as practice, not performance.
Common Mistakes to Avoid
The most frequent error is rounding the lower back as you hinge forward. This shifts the load from your hamstrings and glutes onto your spinal discs, which is where injuries come from. If you notice your back rounding, the weight is too heavy or you’re hinging too far forward for your current flexibility.
Locking your knees completely straight is another common issue. A slight bend protects the knee joint and actually allows a deeper, more effective hinge. You’re not trying to squat, but your knees shouldn’t be rigid either.
Finally, many people place the bar too high on their neck instead of across the upper back. The bar should sit on the muscle of your traps, roughly where you’d carry it for a low-bar squat. Too high and the bar rolls toward your neck as you hinge forward, creating an uncomfortable and unsafe position.
