Rounded shoulders, a head that juts forward, an arched lower back, one shoulder higher than the other, feet that turn in or out: these are the posture patterns people most often notice in photos and mirrors. Simple strength and stretching exercises can make these positions feel easier to change, and they are worth doing for comfort, mobility and strength. But the popular idea that “bad posture” is quietly ruining your health is not well supported by research. Studies have not found that any one posture causes back pain, and people with both upright and slouched postures get it.
This guide covers six common patterns, a simple exercise for each, a quick way to check yourself, and what the evidence actually says.
Posture and pain: the short answer
Back pain is the leading cause of disability worldwide, so it makes sense that people look for a cause they can fix. Posture seems an obvious candidate. Yet systematic reviews comparing adults with and without back pain have found no consistent differences in how they sit or stand. A large study of teenagers found little support for the idea that slumped sitting predicts later back pain, and a review of lifting studies found no evidence that lifting with a rounded back causes it.
Researchers writing in The Conversation estimate that about 90% of back pain is not linked to any identifiable tissue damage, and that only 1 to 5% of cases come from a specific problem such as a fracture, infection, tumour or nerve compression. Stress, low mood, poor sleep and inactivity make people more vulnerable, and fear of moving makes pain more likely to persist.
So treat the exercises below as general fitness, not as repairs to a broken body. Some older articles on this topic claim that poor posture shifts spinal bones out of place and pinches nerves all over the body. That idea, often described as “subluxation”, is not supported by evidence.
Upper body: rounded shoulders and forward head
Rounded shoulders
What it looks like: shoulders that roll forward and inward, often with the upper back curved. It is common in people who spend long hours at a desk or phone, and it is often linked to weaker muscles in the middle and lower part of the trapezius, the broad muscle across the upper back.
Exercise: lie face down with your arms out to the sides, elbows bent at a right angle so your hands point forward, as if you were raising both arms in surrender. Keeping that angle, lift your arms a little off the floor by drawing your shoulder blades back and together. Hold for about five seconds, lower, and repeat. Two or three sets of 12 is a reasonable daily target.
Forward head
What it looks like: the ear sits in front of the shoulder when seen from the side, a pattern often blamed on screens and nicknamed “text neck”. The muscles at the back of the neck can feel tight.
Exercise: the chin tuck. Sit or stand tall and, without tilting your head down, glide your chin straight back so you make a small double chin, feeling a gentle stretch at the base of the skull. Hold for a slow count of five and repeat ten times. It is a handy one to do at a desk.
Trunk and hips: pelvic tilt and a higher shoulder
Anterior pelvic tilt
What it looks like: the front of the pelvis tips down, the lower back arches more than usual and the belly pushes forward. It is frequently associated with tight hip flexors from long periods of sitting. Some degree of curve is completely normal, and the “ideal” amount varies from person to person.
Exercise: a kneeling hip flexor stretch. Kneel on your left knee with your right foot flat in front of you. Squeeze your left buttock and shift your weight gently forward until you feel a stretch across the front of the left hip. For a deeper stretch, reach your left arm overhead and lean slightly to the right. Hold for about 30 seconds and do three on each side.
One shoulder higher than the other
What it looks like: in a front-on photo, one shoulder sits visibly higher. Small differences are normal, especially on your dominant side. A larger tilt may reflect weak muscles that pull the shoulder blade down, a habit such as carrying a bag on one side, or occasionally a spinal curve such as scoliosis, which is worth having checked by a doctor.
Exercise: seated shoulder depressions. Sit on a sturdy chair with your palms flat on the seat beside your hips and arms straight. Without bending your elbows, press down through your hands so your shoulders drop away from your ears and your hips lift slightly. Hold for five seconds; aim for two or three sets of 12.
Legs and feet: pigeon toes and duck feet
Pigeon toes (in-toeing)
What it looks like: the feet and sometimes the kneecaps point inward. In adults, weakness in the glute muscles that rotate the hip outward is a common suggestion.
In children, in-toeing is very common and usually not a posture problem at all. It typically comes from the way the foot, shin bone or thigh bone is shaped during growth, and most cases correct themselves by around age 8 without treatment. Braces and special shoes have not been shown to help with the commonest types. If you are worried about a child’s walking, ask your doctor.
Exercise: the clamshell. Lie on your side with knees bent to 90 degrees and heels together. Keeping your feet touching and your hips still, lift the top knee like a shell opening, pause for five seconds, then lower. Two or three sets of 12 per side.
Duck feet (out-toeing)
What it looks like: toes that point outward by more than about 10 degrees when you stand relaxed. Fitness writers often link it to weak deep core and hip muscles or tight muscles around the back of the hip, though the shape of the bones also plays a large part.
Exercise: the stability-ball knee tuck. Start in a push-up position with your shins or feet resting on an exercise ball. Keeping your back flat, bend your knees and roll the ball towards your chest, then straighten out again. Two or three sets of 6 to 12 repetitions. If that is too hard, a plank on the floor works the same core muscles.
A two-photo posture check
Wear fitted clothes, stand relaxed with feet about hip-width apart and ask someone to take one photo from the front and one from the side. Then look for these signs:
- Ear position: in the side view, an ear well in front of the middle of the shoulder suggests a forward head.
- Shoulder blade: if the side view shows the shoulder blade sticking out, the upper back may be rounded.
- Lower back: a deep arch with the hips tipped forward and the stomach pushed out suggests anterior pelvic tilt.
- Shoulder height: in the front view, check whether one shoulder sits noticeably higher.
- Kneecaps: kneecaps that point towards each other may go with in-toeing.
- Feet: toes angled outward well past 10 degrees indicate out-toeing.
Remember that everyone’s body is a little asymmetric. These checks tell you where to focus your stretching and strengthening, not whether you are healthy.
Myths about posture
“There is one correct way to sit.” No single posture has been shown to protect the back. The best posture is usually the next one: changing position often matters more than holding any particular shape.
“Slouching damages your spine.” Spines are strong and adaptable. Slouching for a while may feel stiff, but there is no good evidence that it causes lasting harm.
“Always lift with a straight back.” Research has found that experienced manual workers without back pain often lift with a rounder back, while those with pain tend to lift stiffly with a straight back. Ergonomic advice and lifting training have not been shown to reduce work-related back pain.
“Good posture fixes back pain.” In one small study, people recovering from disabling back pain actually relaxed their protective, upright postures as they improved.
What actually helps, and when to see a doctor
Most back pain improves within a few weeks. The approaches with the best support are to stay active and keep up daily activities, build general strength and fitness, sleep well and look after your stress and mood. Walking, swimming, yoga and Pilates can all help, and the exercises above are a reasonable part of that mix. Stop any exercise that makes pain clearly worse.
Talk to a doctor if pain does not improve after a few weeks, stops you doing everyday things, comes with unexplained weight loss, is worse at night or sits between the shoulder blades. Seek urgent help if you have weakness, numbness or tingling in both legs, numbness around the genitals or bottom, trouble controlling your bladder or bowels, or pain after a serious accident.
