#20 Proven Bone-Building Exercises for Midlife and Beyond | Professor Belinda Beck
18 Jan 2026
Chapter 1: What is the main topic discussed in this episode?
Welcome to Mind Your Being. Whether you're a returning listener or you're new here, I'm so grateful you're taking a little time out of your day to care for your health and well-being. I'm so excited to release today's episode of Mind Your Being.
I'm joined by Professor Belinda Beck, a world-leading researcher in bone health and exercise science, to talk about how our bones really respond to movement, nutrition and lifestyle as we age. We explore why it's never too late to strengthen your bones, the types of exercise that genuinely make a difference,
We also discussed the groundbreaking findings showing that even postmenopausal women with osteoporosis can improve bone density with the right exercise, the right supervision and the right program. I want to encourage you to listen to this conversation because the choices we make in midlife shape how strong, mobile and independent we feel for decades to come.
If you're in midlife and wondering how to care for your body in a way that supports long-term strength and quality of life, you're going to love this episode. Please enjoy. Welcome to Mind Your Being, Belinda. Thank you for making the time today. Pleasure. Lovely to be here.
I've asked you on today to talk about how exercise benefits our bones across our whole life and to talk about the findings, which were surprising to some, from your research on postmenopausal women with low to very low bone mass.
But before we get into all of that, could you please tell us a bit about your background and how you came to be interested in the relationship between exercise and healthy bones?
Yeah, as many people do, I got into the area because I had sore shins when I ran. And so... That got me thinking, you know, as a very young athlete, what's going on? This doesn't make any sense. I'm very healthy and I don't understand why I've got this sore bit on my bones.

Chapter 2: What are the benefits of exercise for bone health?
So the start of my research career was really into bone stress injuries. But that morphed into an interest into the effect of exercise on bone in general because in actual fact, Bone stress injuries tend to look after themselves. They tend to get better if you just rest them, whereas osteoporosis is something that goes the other way.
You develop it as you age, typically, and once you have it, you need to do something active. to try and improve the bone mass. So it's a huge problem. It is prevalent. It is expensive. It's painful. It really impacts people's quality of life and it shortens people's life and it shortens their health span. So the number of years where they are happy and healthy.
So it just became an interest just of the public health need. And, of course, underlying everything that I do is the importance of exercise and the benefit to all our systems.
I have to admit, I'm one of those people who didn't really, I didn't know a lot about bone and I didn't think a lot about bone until I hit menopause. And then you start to really think about and hear about how important bone health is. So I think it's the public health need is really important.
And to look at it from the preventative lens as well, what can we do to have that longer health span, as you said?
Yeah, that's right. Nobody thinks about their bones until they break something. They're just there. They're invisible and they do their stuff very quietly.

Chapter 3: How can postmenopausal women improve bone density?
It's not all about just holding us up, you know, supporting us. They help us move because the muscles need things to pull on. So actually, they're really important for movement. But also, they are this reservoir of minerals and other substances that help our body function. So they're the calcium bank. We need calcium. We go to the calcium bank and make withdrawals.
So it's a very metabolically active tissue, really important that we pay attention to it. And as you say, we don't tend to until we are actually at a point where we're having fractures or we're at risk of fractures.
I wish we learned more about this earlier. It's so important. In a previous episode, we had a guest, Dr. Tracey Clissold on, and she talked about the importance of building strong, healthy bones, that important window up until the age of 30.
But for people who didn't listen to that episode, could you please explain what's happening with the building of bones in our first 30 years and why it's so important for parents to understand this?
Yeah, well, it actually makes perfect sense when somebody tells you about it. But it's still normally surprising when I say to people, we have all the bone we're ever going to have by the time we're about 20. For men, it's a little longer than that. But yeah, so... And that's referred to as your peak bone mass, because if you kept growing more bone, we would all be enormous.
So we do, you know, when you stop growing after puberty, largely your bones, your growth plates fuse and you stop growing in length, but the bones sort of consolidate a little bit as you get slightly bigger, as you finish growing into maturity. But that is the most bone you're ever going to have.
We know now that the most important thing you can do to reduce your risk of fracture at the end of life is to optimize your peak bone mass. And so that window is only open in those growing years, the first two decades of your life, basically. There are a couple of periods where we grow like crazy, the very young years, like newborn through to age two.
We're growing like crazy, and you'd see that almost before your eyes. And then the next growth spurt is puberty. And that's particularly in boys. You can see that happening almost as you watch them. Really, really important.
And those times that there's enough available nutrition and the loading that the bones are experiencing is healthy loading so that the bones grow in the best possible way that they can and grow as much as your genetic potential will allow. because genes do determine really the bone that we have.

Chapter 4: What groundbreaking findings were revealed in the LIFTMOR clinical trial?
And so if you are somebody who has played a lot of, let's say, rugby league all your life, that is a very intensive activity. heavy loading kind of exercise. And so that will make your bones adapt to that kind of exercise and be strong enough to accommodate that without breaking. And you could replace rugby league with any other very heavy loading exercise.
On the contrary, if you go into space and you unload your bones because you take away the force of gravity, and the need for the muscles to contract strongly to move you through the air, your bones will resolve and you'll actually get rid of a lot of bone. And we can create a bit of a model of microgravity by putting people in bed rest. That's also unloading the skeleton and so bone will resolve.
Putting a cast on your arm will make the muscles not use that as much. And so you will actually lose bone in that immobilized limb, spinal cord injury, unloading the parts of the body that are no longer weight-bearing and so on. So bone is extremely responsive to load. But in the main, we have a genetic blueprint that tells our body, our skeleton, to grow to a certain size.
If we underload it, you probably won't grow as much as you possibly could. And if you overload it, you might grow a little bit more. And so this is the principle of overload and how we can harness that to improve our bone mass and health throughout life. At any time of life, the principle applies. If you unload, you'll lose bone. If you overload, you'll grow bone.
And that can still be applied in old age.
Yes, and that's what we're going to talk about. Before we get to the LIFMO study, can you please explain what starts to happen after 30 or after 20 in terms of bone loss and also how bone loss is accelerated at the time of menopause?
Yeah, sure. So it's sort of along the same lines as what I was just talking about, loading and unloading. If you remain as physically active throughout young adulthood as you were, you know, when you gained your peak bone mass, you should hang on to most of that bone. You know, it... that is helping you to hold on to that bone.
But typically, people are not as active as they're older as they were when they were younger. And so after you've sort of gained your peak bone mass, and let's say that's around 25, we'll split the difference between men and women, say it's about 25, After that, you sort of plateau for a little bit and then you'll gradually begin to lose bone mass.
Now, at the age around menopause, what causes menopause is the withdrawal of circulating estrogen. Estrogen is extremely protective of bone because it helps to inhibit or slow down the activity of one of the bone cells that resolves bone. And that resorption is really important for things like, you know, when you go to the bone bank and get some calcium out,

Chapter 5: What types of exercises are effective for building bone strength?
you know, somebody with another condition, then Oniro is absolutely reducing fractures and it is saving the government $35,000 per hip fracture, and that's just one kind of fracture. So it is absolutely, you know, an economically viable model. We're hoping to get the data to do that. And then imagine if you could go to Oniro and actually get Medicare reimbursement for that. Yeah.
that would change the landscape in fractures in Australia.
I'm so glad you say that stop fracture is doing that because that's what I had in mind, like more awareness for doctors. And then as you say, you need someone in the government with foresight to look more at prevention because it costs so much money and falls how much money they cost the government as well.
what's, like you said, giving someone a Medicare rebate to participate in O'Neill is going to save the health system so much money downstream.
And when you consider that resistance training is known to be beneficial for virtually every other system in the body, giving a rebate for Oneiro is actually also giving a rebate for the exact same program is helping all those other conditions. And so it's bringing blood pressure down. It's improving mental health. And metabolically, this is improving people with diabetes.
So it's such a win-win. It's a difficult job to make people aware of it because, of course, now I have a conflict of interest because the bone clinic is... a business and O'Neill is a product. But there was no other way of doing this. And so it's a little bit of a problem.
But on the other hand, I'm also generating, you know, industry and more tax for the government if I sell a license and people are actually gaining revenue. So everything about it is very beneficial. It's just the fact that I'm one person and I'm a full-time professor. I know, I know.
But someone's always, you say the conflict of interest, but it doesn't matter. You've still got the research. Someone is going to make money out of it somewhere. But we're talking about the health system, people's quality of life, but that impact to save so much money downstream. As you said, it impacts all our cardiovascular systems, our mental health.
Do you have, like, have you captured some of that data as well? And I know, like, you've got so much to do. So I'm hoping someone in the government could say, hey, I need to look into this because you can present them with the data.
