How To Increase Bone Density After 50: Load It Where You Want It
How to increase bone density: the short answer
How to increase bone density after 50 comes down to one rule: bone builds where you load it, and nowhere else. Walking is good for you, but it loads the legs in one direction and does almost nothing for the wrists, shoulders and spine. Load the whole body, from many directions, for months and years.
A held yoga pose, using your own body weight, is load. Here is the article in short form:
- Racquet players’ playing arm holds up to 16% more bone.
- Bones thin from about 30, fastest around menopause.
- Walking misses the wrists, shoulders and spine.
- Standing on one leg doubles the load on that hip.
- 74 trials: mind-body exercise plus strength did best for bone.
- Shape matters: a long spine shares the load.
A quick word on Iyengar yoga. Iyengar yoga is the style developed by Mr BKS Iyengar. In the 20th century he did more than anyone to set down traditional Indian yoga, through his books and his teaching, and he pioneered the use of props. It is the style we teach at Flametree, in Darwin and live online.
A held standing pose is load. The legs and hips carry the body for many breaths, from more than one direction.
Why does bone only build where you load it?
Because bone answers the forces it feels. In 1995 Finnish researchers measured the arms of women who played tennis or squash at a high level. The bones of the playing arm held 8 to 16% more mineral than the other arm, against 3 to 5% in women who did not play.
Same person, same genes, same diet. The only difference was which arm swung the racquet.
So a practice that loads the whole body, from many directions, has a real advantage over one that loads only the legs, in the direction they already know.
Same person, same genes, same diet. The playing arm carries far more bone. Load builds bone, but only where the load goes.
Why does bone loss speed up after menopause?
Bone builds to a peak around 30, then slowly thins. In the years around menopause, as oestrogen falls, it thins fastest. On average, women can lose up to 10% of their bone density in the first five years after menopause.
Men lose bone too, a little later and more slowly, and men fall too. This matters for everyone over 50.
One Flametree student, K, wrote after a long Sunday class on bones: “Having osteopenia myself, it made me realise how important it is to ‘work’ my bones particularly as I get older.” Osteopenia means bones thinner than normal. K’s point is the point of this article. Bones can be worked, and it matters more with age, not less.
Bones reach their peak around 30, then thin, fastest around menopause. That is why the work matters more, not less, with age.
Is walking enough to build bone density after 50?
Walking is good for you, but on its own it is not enough. It loads the legs a little, in one direction. Almost nothing in an ordinary week loads the wrists, the shoulders or the upper spine.
The wrist deserves special attention. Flametree’s teachers point out that it is often the first bone a woman breaks, usually by putting a hand out in a fall. Poses on the hands, such as Downward Facing Dog and Plank, are one of the few ways an ordinary week ever loads the wrist.
Standing on one leg is another. On two feet each leg carries about half your weight. Lift one foot, as in Tree Pose, and the standing leg, hip and foot carry all of it, while the brain works to keep you upright. Margaret Martin, a Canadian physiotherapist, makes this point in Yoga for Better Bones.
Where the load goes. Walking loads the legs one way. A yoga class reaches the wrists, shoulders and spine as well.

What does the research say about yoga and bone density?
It is promising, and still growing. Here is where the reviews stand:
- 2024, 11 trials, 1,005 women around and after menopause: mind-body exercise, including yoga, raised bone density.
- 2021, 11 studies, 591 women aged 45 to 78: no clear change, though keeping bone steady at an age when it usually falls is itself a good result.
- 2026, 74 trials, 5,331 women after menopause: mind-body exercise combined with strength work came out best for bone density at the spine and the top of the thigh bone.
That last finding matters for yoga. A well-taught Iyengar class is strength work too: standing poses held until the legs shake, and body weight carried on the hands. Programmes of a year or more gave the most consistent gains.
No trial has yet tested a full Iyengar practice, with weight on the hands, jumps and inversions, for bone. Not measured is not the same as disproven. It matches, in kind, the loading bone is known to answer.
Is a gentle yoga pose really weight bearing exercise for bones?
Gentle does not mean passive. Picture a Triangle Pose held for a minute, a block under the lower hand, the outer edge of the back heel pressed into the floor. It is quiet to look at and demanding to do.
The muscles of both legs work the whole time, pulling on the bones they attach to. Chris describes a yoga pose as a set of muscles pulling in two directions at once, like the guy ropes on a tent. Every pull on a bone is itself a form of load.
Propped does not mean watered down either. A chair under the hand or a wall behind the back foot lets the pose be held accurately, and for long enough to count. That is why Mr Iyengar pioneered props: not to make a pose easier, but to make it possible to do properly, in a body of any age.
Propped does not mean watered down. A chair lets the pose be held accurately, and for long enough to count.
Does the shape of the pose matter for bone?
Yes, a great deal. Margaret Martin explains that weight-bearing with the back rounded, bending over the garden bed or reaching for your toes, shifts the load onto the front of the spine bones, where they are least dense inside. Carry the same load with a long spine and it is shared far better.
So the rule in an Iyengar class is length before depth. Lift and lengthen the spine first, then go into the pose. For thin bones, a modest pose with a long spine does far more good than a deep pose with a rounded back. Fold forward from the hips, never by rounding the back under load.
How quickly does bone respond?
Slowly. Bone takes months to change, and a scan has its own margin of error of a few percent. Strength and balance change much faster, often within 12 weeks. In a Sydney pilot study in 2013, 54 people with an average age of 68 did 12 weeks of Iyengar-based yoga, and their balance, walking speed and getting up from a chair all improved.
That is why we think of it as two timescales. Come for the steadiness you will feel in weeks. Stay for the bone that builds over years.
From the wall, to a chair, to no support, to eyes closed. Each stage asks a little more of the legs and hips.

Frequently asked questions
What is the best way to increase bone density after 50?
Load the whole body, from many directions, regularly, for a year or more. A 2026 review of 74 trials in women after menopause found mind-body exercise combined with strength work did best for bone density. Body weight on the hands and standing on one leg add load that walking misses.
Is walking enough to keep bones strong?
Walking is good, but it loads the legs in one direction and does almost nothing for the wrists, shoulders and spine. Bone builds only where it is loaded, as racquet players’ arms show. Add work that loads the upper body and the hips from other directions.
How much bone do women lose after menopause?
On average, women can lose up to 10% of their bone density in the first five years after menopause, as oestrogen falls. That is why the years around menopause are the time to start loading bone, not to slow down.
Can you build bone with body weight alone?
Body weight is real load when it is held well. Standing on one leg puts your whole weight through that hip, and Downward Facing Dog and Plank load the wrists and shoulders. Holding standing poses until the legs work hard is strength work too.
Why does the wrist matter for bone health?
The wrist is often the first bone a woman breaks, usually by putting a hand out in a fall. Ordinary daily life hardly loads it. Poses with weight on the hands are one of the few ways to work the wrist bones regularly.
Does the shape of a pose matter for bone?
Yes. Physiotherapist Margaret Martin explains that load taken with a rounded back lands on the front of the spine bones, where they are least dense inside. The same load with a long spine is shared far better. That is why Iyengar teaching lengthens the spine before going deeper.
How long does it take to build bone density?
Bone changes slowly, over many months, and a scan has a margin of error of a few percent. Programmes of a year or more gave the most consistent gains. Strength and balance improve much faster, often within 12 weeks.
Where can I work on my bone density in Darwin?
