Yoga for back fat: what it is, posture and bra lines, why no pose burns it, what helps, the evidence, and a class

Ordinary fat, normal at any size

Back fat is the fat you can pinch on your upper back and along your bra line. Where your body keeps fat is largely inherited, and women carry more fat under the skin than men at the same size.

Sources 1, 2

No pose burns it

Our searches found no study of back exercises or yoga and back fat. In the arm and leg studies, training one part of the body didn't take the fat off it: on MRI, training one arm took fat off both arms equally in 104 adults.

Sources 3, 4, 5

It changes with your total body fat

In women losing weight, fat under the skin of the trunk fell along with fat elsewhere. More aerobic activity took weight off in a dose-response way across 116 trials, while yoga on its own had no clear effect on body fat across 30 trials.

Sources 6, 7, 8

Yoga builds the back underneath

Locust, cobra, plank, downward dog and dolphin work the back, trunk and shoulder muscles, in small lab studies. A stronger back helps how you sit, carry and move; it doesn't burn the fat over it.

Sources 9, 10

Bra lines are often about fit

In 104 women, 85% wore a bra that didn't fit, and in 102 women referred for breast reduction, all did. Soft folds where a band presses are normal at many sizes.

Sources 11, 12

Some things need a GP, not a workout

See a GP about fat building up on your neck and upper back with thin arms and legs, a lump that grows, hurts or is hard, or an upper back that's newly rounded.

Sources 13, 14, 15

Fat under the skin, not a problem to fix

Back fat sits under the skin of the upper back, around the shoulder blades and along the bra line, and above the hips at the back, where it joins the love handles. Our guide to losing back fat has the full plan; this guide covers what yoga can and can't do.

Genes, sex and ageStrong evidence

In Danish twins, genes explained 82% to 85% of the differences in trunk fat. In an MRI study of 80 adults, women carried more fat under the skin than men at the same BMI (body mass index), and people with insulin resistance carried more in the shoulder and neck region: a pattern across a group, not a reason to worry about your own back.

Sources 1, 2

It goes with the rest of the trunkEmerging evidence

In 57 women who lost about 8 kg on a diet, the fall in breast fat went with the fall in fat under the skin of the trunk, on MRI. Men and women lost fat from the same places in another scan study, and no diet, exercise, medicine or surgery took fat from one place in 89 studies.

Sources 6, 16, 17

Not studied by name

We found no study of "back fat" in people by that name; in research, the term is mostly about farm animals. What follows comes from studies of the arms, legs, belly and whole trunk.

Check the fit firstEmerging evidence

In 104 Australian women, 85% wore an ill-fitting bra, and trying on several bras or using bra-size measurements didn't fix it. All 102 women referred for breast reduction in a UK study wore the wrong size, nearly all with a band size they had underestimated. In another UK study, the traditional tape method overestimated band size. The errors run both ways, so check the fit with a trained fitter rather than assume the band is too tight (our reading).

Sources 11, 12, 18

Fit and the backEmerging evidence

In 30 young women with upper back pain, 80% wore the wrong size, mostly too small. In 24 women with larger breasts, a professionally fitted bra changed support and posture straight away but not after 4 weeks, and most still didn't pass a fit check. None of these studies measured back fat.

Sources 19, 20

Folds are normal

Soft folds where a bra band, strap or waistband presses into the skin happen at many body sizes, and how they look depends on the fit of what you wear as well as on your weight (our reading; we found no study of them).

Source 3

Posture changes how a back looks, not how much fat it has

We found no study linking posture to back fat. Standing taller changes how your back and clothes look. Back-strengthening yoga suits a rounded upper back for its own sake: our yoga for posture guide has the evidence.

Source 3

We found no trial that tested the back

We found no trial of back exercises or yoga on upper-back or bra-line fat. The evidence comes from the limbs and the belly, and nothing suggests the back is different (our reading).

Source 3

Training one part doesn't burn the fat over itStrong evidence

Across 13 studies of 1,158 people, training one arm or leg didn't take more fat off it than off the other. On MRI in 104 adults who trained one arm, fat came off generally. Six weeks of ab exercises didn't shift belly fat in 24 adults. The 13-study review sits in a journal outside the main medical index (MEDLINE).

Sources 5, 4, 21

The small studies that disagreeMixed evidence

A circuit study in 14 adults reported thinner fat over the lower back and under the shoulder blade, but only within one group, in a paper that gives the programme as both 8 and 12 weeks. A trial in 16 men took about 700 g more fat off the trunk (chest, back and tummy together on the scan) with nearly an hour of extra crunches and rotations 4 days a week. Neither shows a slimmer back.

Sources 22, 23

Yoga and body fat: no clear changeMixed evidence

Across 30 trials with 2,173 people: "No effects on weight, body mass index, body fat percentage or waist circumference were found." In 15 trials of people with obesity, weight and body fat didn't clearly change, and the authors call the evidence inconclusive.

Sources 8, 24

Yoga and other exerciseEmerging evidence

Across 37 trials, yoga and other exercise didn't differ for weight or BMI.

Source 25

The back muscles in lab studiesEmerging evidence

High plank, low plank and downward dog worked the side tummy muscles most of 11 poses; boat pose worked the front trunk muscles above half their maximum and plank about a third, in 22 trained people; a dolphin plank drove every tummy and back muscle measured to very high levels in another small study, a figure to read with care. These show effort, not results.

Sources 9, 26, 10

Hot yogaEmerging evidence

Heat raises heart rate and sweat but not energy use, and the weight lost in a hot class is water and salt, replaced within about a day.

Sources 27, 28

Move moreStrong evidence

In 116 trials of adults with overweight or obesity, each extra 30 minutes a week of aerobic exercise took off about half a kilo, with changes that matter from about 150 minutes a week. Build towards at least 150 minutes a week at a pace where you can talk but not sing, as the NHS advises.

Sources 7, 29

Eat a little lessStrong evidence

"Diet is the important factor in weight management", say the UK Chief Medical Officers. NICE advises against restrictive diets that are nutritionally unbalanced, and the NHS suggests aiming for 0.5 to 1 kg a week if you want to lose weight.

Sources 30, 31, 32

Strength train on 2 days a week, with a pullStrong evidence

Strength training trimmed body fat by about 1.5 percentage points in healthy adults and helps keep muscle while you lose fat. Yoga counts as strength work for the NHS; add a row, because yoga has no pulling move.

Sources 33, 34, 29

Fat comes off the trunk with the rest of youEmerging evidence

In a scan trial, diet with exercise took fat off the tummy and trunk in both men and women, and across 89 studies fat under the skin and fat around the organs fell together.

Sources 16, 17

Bow pose, for now

It's a favourite on back fat lists, but it's a hard backbend. Its move page says it's "Not for anyone with a recent shoulder dislocation, and skip it in pregnancy. Stop if your low back pinches rather than works." Leave it out with osteoporosis too, as our osteoporosis guide advises.

Breath of fire

Our searches found no trial of it for fat, and US health advice says newcomers should avoid forceful breathing. Leave it out (our suggestion).

Sources 35, 36

Forward folds in sun salutations, with osteoporosis

Modify or avoid exercises that round your back deeply or repeatedly, especially with a weight: sit-ups, toe touches, Pilates roll-downs and curl-ups, and extreme yoga forward folds. Bend from the hips instead. You do not need to avoid bending, twisting or lifting altogether: move smoothly and keep your upper back straight.

Jump-backs

Step back instead, as the walk and yoga workout does, if jumping is uncomfortable for your joints or your pelvic floor.

In pregnancy

Staying active is good for you: the NHS advises 150 minutes of moderate activity a week, including muscle strengthening. This isn't the time to diet for back fat (our view); ask your midwife before starting anything new.

Face-down poses get uncomfortable as your bump grows: swap them for all-fours moves such as bird dog, as the cobra pose page advises.

Source 37

A sore shoulder

Dolphin loads the shoulders overhead, and its page asks you to clear a shoulder impingement or recent rotator cuff problem with a clinician first. Keep your arms lower in chair pose and the raises small (our suggestion).

Low back pain that sharpens with arching

Ease off the backbends, as the low cobra page advises, and stop if pain travels into a leg. Our yoga for back pain guide has the rest.

Living with a higher weight

Start where you're comfortable: chair, wall and standing versions all count. Our yoga for plus-size bodies guide and class cover getting up and down from the floor.

Stop and get medical help

If you get chest pain or pressure, feel faint or dizzy, are unusually breathless, or your heart races or beats irregularly during exercise, as our plans advise.

Call 999 (911 in the US)

For chest pain that comes on suddenly and doesn't go away, or spreads to your arms, neck, jaw, stomach or back; or back pain with chest pain, with numbness, tingling or weakness in both legs, with loss of feeling around your genitals or bottom, or with changes in your bladder or bowels. Don't drive yourself to A&E.

Sources 38, 39

Chest pain or fainting while exercising: call 999

Call 999 if:

• You get sudden pain or discomfort in your chest that doesn't go away; it can feel like squeezing or pressure, burning or indigestion.
• The pain spreads to your left or right arm, or your neck, jaw, stomach or back.
• You have chest pain and feel sweaty, sick, light-headed or short of breath.
• Someone faints while exercising, can't be woken within 1 minute, or has chest pain or a pounding, fluttering or irregular heartbeat.

Sources 38, 40

Unusual breathlessness

Call 999 or go to A&E (accident and emergency) straight away for severe difficulty breathing (gasping, choking or not able to get words out), a chest that feels tight or heavy, pain that spreads to your arms, back, neck and jaw, lips or skin turning very pale, blue or grey, or sudden confusion. If you're more short of breath than usual, or your heart is racing, fluttering or skipping beats, contact NHS 111.

See a GP

See a GP if:

• fat is building up on your neck, upper back, chest and tummy while your arms and legs look thin, with a red, round face, easy bruising, stretch marks or weak muscles: it could be Cushing's syndrome, especially if you take steroid medicine (don't stop steroids without talking to your doctor)
• you find a lump anywhere on your body, or a lump is painful, red or hot, hard and fixed, growing, or still there after 2 weeks: many soft lumps on the back are lipomas, which are harmless, but a GP should check
• your upper back is newly rounded or hunched: it could be kyphosis

A hump at the base of your neck

A soft pad of fat over the base of the neck, a rounded upper back and a lipoma can look alike. Our neck hump guide explains how to tell them apart.

See a GP: bloating, losing weight without trying, or fat building up

If you feel bloated regularly, or have bloating with weight loss you can't explain or blood in your poo: the NHS says bloating that doesn't go away can sometimes be a sign of something more serious, such as ovarian cancer, whose symptoms include a swollen tummy or feeling bloated roughly 12 or more times a month. If you're losing weight without trying: it "can be a sign of stress or a serious illness. See a GP just in case." And if fat is building up on your tummy, neck and upper back while your arms and legs look thin, with a red, round face or stretch marks, especially on long-term steroid medicines: this can be Cushing's syndrome.

Sources 44, 45, 46, 13

Gaining weight you can't explain, in the NHS's words

The NHS lists health conditions that cause weight gain, such as an underactive thyroid, Cushing's syndrome and PMOS (polyendocrine metabolic ovarian syndrome, the new name for polycystic ovary syndrome), and "certain medicines including some steroids, antidepressants and beta blockers". It says: "Speak to a GP for advice if you have a condition that makes it harder to stay a healthy weight." Don't stop a medicine without talking to your doctor (our suggestion).

Help to lose weight

The NHS suggests seeing a GP if your BMI is in the overweight or obese range and your waist is more than half your height, and a GP can refer you for support.

When eating or exercise becomes harmful

The NHS lists spending a lot of time worrying about your weight and body shape, eating very little food, exercising too much, and having very strict routines around food among the signs of an eating disorder, and says to see a GP as soon as you can. Worrying a lot about one area of your body can be body dysmorphic disorder. Beat's helpline in England is 0808 801 0677, and our eating disorders guide has the other numbers.

Sources 47, 48, 49

Yoga doesn't protect against it

In a survey of 2,287 young adults, women who did yoga or Pilates had disordered eating as often as those who didn't, and men who did them reported more extreme weight-control behaviours (18.6% against 6.8%). Set goals for strength, control and how you feel, not calories burned.

Medicines for diabetes or weight loss

If you take insulin or a sulfonylurea, exercise can bring on a hypo: see our type 2 diabetes guide. If you're on weight loss injections, see the exercise advice in our exercise for weight loss guide.

Check with your GP first

If you haven't exercised for some time, or you have a medical condition or concerns, speak to your GP before starting. If you take insulin or another medicine that can cause low blood sugar, our type 2 diabetes guide covers exercising safely.

A heart condition

If you have a heart condition, follow your cardiac team's advice on how hard to work, and stop for the warning signs above. People with long-term conditions may wish to ask their specialist before starting. With uncontrolled high blood pressure, avoid straining against a held breath; the high blood pressure guide has more.

During yoga

A joint pain that is sharp, gets worse during a session, lingers into the next day or changes how you move is a reason to use an easier version, and to see a GP or physiotherapist if it keeps happening (the rule in our plans). Muscle soreness for a day or two after something new is normal. In a hot class, stop if you feel dizzy, sick or unwell; our hot yoga guide lists the signs of heat illness.

You can say no to any hands-on adjustment, and a teacher registered with Yoga Alliance must get your explicit consent each time.

Head-down poses, bones and pregnancy

With glaucoma, or high blood pressure that isn't under control, skip headstands, shoulder stands and long head-down holds. With osteoporosis, swap deep forward folds for a flat-back hinge from the hips, and twist smoothly. In pregnancy, our yoga in pregnancy guide covers the changes. NCCIH advises beginners to avoid headstands, shoulder stands, the lotus position and forceful breathing.

Before you start

The NHS advises getting advice from a healthcare professional first if you have a health problem, an injury or symptoms, or have recently had a heart attack or an operation.

If you have a heart, lung or joint condition, are pregnant or have recently been unwell, start gently and read our guide for your condition. Muscle soreness for a day or two after a new exercise is common and fades as you repeat it.

"Back fat is something to hide"

It's ordinary fat that most people have, at many sizes. Train your back because a strong back is useful, not to fix how it looks (our view).
