Your bones are losing density right now. Here is what stops it.
Somewhere along the way, a lot of women in their 40s and 50s start receiving the same kind of advice: slow down, protect your joints, avoid anything high-impact. It comes from a caring place. But it is, in many respects, doing the opposite of what your body actually needs right now.
Because here is the biological reality: oestrogen is one of the primary hormones responsible for maintaining bone density. And from perimenopause onwards, oestrogen levels drop. For some women, that drop is steep and fast. Research has found that around 25% of women experience accelerated bone mineral density loss during the menopausal transition.
Bone is not static. It is living tissue in a constant cycle of breakdown and rebuilding. What drives the rebuilding side of that cycle? Mechanical load. Impact. Stress on the skeleton that signals bone-forming cells to get to work.
Telling a perimenopausal woman to rest more and avoid impact is removing the primary stimulus her skeleton needs to hold onto its density. That is a problem.
Why bones get stronger from impact, not from rest
The science here is well established. Bone tissue responds to mechanical strain. When you load your skeleton, including through high-impact movements like jumping, ground reaction forces travel through the skeleton and trigger osteoblast activity. Osteoblasts are the cells responsible for building new bone.
The rate at which that force is applied matters too, not just the magnitude of it. This is why plyometric movements, including relatively modest ones like jump training, are considered particularly effective for stimulating bone formation.
Research published in Translational Sports Medicine found that simple jumping exercises in post-menopausal women produce significant osteogenic loading at the hip, and concluded that jumping exercises should be included in rehabilitation and training programs aimed at improving bone health in this population. A 2018 study noted that these exercises are “easily implemented” and do not require high-intensity effort to be effective.
You do not need to jump high. You do not need to be an athlete. You need to load your skeleton. Three to five minutes of this kind of work, a few times a week, is enough to create a meaningful stimulus.
What this looks like inside Legacy classes
Jump training is in our classes for a specific physiological reason. Every session that includes plyometric elements and impact movements is doing exactly this kind of skeletal loading work. The movements are scaled to the individual. You are never pushed beyond what your body is ready for. The goal is consistent, progressive load, not performance for its own sake.
Want to understand more about how we structure our training and why? Our approach to strength-based training explains the thinking behind every session.

The full picture: what else supports your bones right now
Exercise is the most controllable lever you have for bone density. But it works best when it sits inside a broader picture of your health. Here is what the evidence points to.
Protein
Bone is not just mineral. It is roughly one third protein, primarily collagen, which forms the structural matrix that gives bone its flexibility and tensile strength. Protein intake is consistently associated with better bone density outcomes in perimenopausal and post-menopausal women.
Current evidence suggests women in this phase of life benefit from aiming for at least 1.2 grams of protein per kilogram of body weight per day. For a 70 kg woman, that is around 84 grams daily — substantially higher than the standard recommended dietary allowance, which represents a minimum to prevent deficiency rather than an optimal intake for muscle and bone preservation.
Most women find they are well below target. And the gap is often not from lack of effort — it is just that no one has ever shown them what adequate protein actually looks like across a day.
If you are not sure where to start, that is exactly what our nutrition coaching is designed for. We work with you to build a realistic picture of your intake, find the gaps, and make simple adjustments that fit your life. No meal plans. No restriction. Just a clearer understanding of what your body actually needs.
Calcium and vitamin D
These two work together and both matter. Calcium is the primary mineral in bone. Vitamin D is essential for calcium absorption and bone metabolism. Many Australian women, particularly those who spend limited time outdoors, have suboptimal vitamin D levels without knowing it. A blood test through your GP is the most reliable way to check.
Dietary calcium from food sources, including dairy, leafy greens, and fortified foods, is preferable to high-dose supplements for most women. Talk to your GP or an accredited practising dietitian before reaching for calcium tablets, as the evidence around high-dose supplementation is more nuanced than the marketing suggests.
Resistance training alongside impact work
Jump training is powerful, but it works best as part of a broader strength program. Research consistently finds that the combination of aerobic and resistance training produces the strongest outcomes for bone mineral density at key sites, including the lumbar spine and femoral neck. This is exactly the structure we use at Legacy. Impact work does not sit alone — it sits inside a program built around progressive strength.

Alcohol and smoking
Both are directly associated with reduced bone mineral density and increased fracture risk. Not a lecture — just information worth having when you are actively working to protect your bones long term.
Impact training and joint protection are not in conflict when the program is designed well. The key is appropriate progression, adequate recovery, and building strength in the muscles surrounding the joints before increasing load.
If you have existing joint concerns, osteoarthritis, or a recent injury, speak with us before starting. We will find an approach that works for your body. "Protect your joints" is rarely a reason to avoid all loading — more often, stronger surrounding muscles mean better-supported, better-functioning joints.
Hormones: the conversation worth having
The drop in oestrogen that accompanies perimenopause and menopause is directly linked to accelerated bone loss. Menopausal hormone therapy (MHT, also referred to as HRT) is well supported by evidence as a means of maintaining bone density and reducing fracture risk.
The Australasian Menopause Society notes that for the majority of symptomatic women under 60 who start MHT within ten years of menopause, the benefits of treatment outweigh the risks. Menopause Alliance Australia similarly highlights that MHT helps maintain bone density and reduces fracture risk, while acknowledging that, like all medications, it carries both benefits and risks that vary by individual.
This is not a simple yes or no decision. MHT is not right for everyone. But the evidence base has been substantially updated since the early 2000s, and many women are still carrying fears rooted in research that has since been reappraised. If this is on your mind, a GP with genuine expertise in this area is the right starting point.
Many Legacy members see Dr Atreyi Bala at East Ringwood Clinic for GP care and women's health support, including perimenopause and HRT conversations. Dr Bala has a listed special interest in menopause and women's health. We have heard great things — this is community word of mouth, not a formal referral arrangement.

This is what strong women training smart actually looks like
It is not extreme. It is not punishing. It is not chasing a number on a scale while your skeleton quietly loses ground.
It is showing up consistently. Lifting progressively. Eating enough protein. Having honest conversations with your doctor about what your hormones are doing. And doing three minutes of jump training in a class with a room full of women doing exactly the same thing, for exactly the same reasons.
At Legacy, we build capable, strong women with the knowledge and physical foundation to live well for a long time.
If you have been putting this off because you thought you were not the type, or because someone told you to take it easy, this is your invitation to reconsider.
I'd spent years being told to take it easy. I started at Legacy not really knowing what to expect, and within a few months I just felt different. Stronger. More capable. Like my body was finally working with me instead of against me.
Melissa KCommon questions
If something is stopping you from taking the next step, the answer is probably here.
Is jump training safe if I have bad knees or joint concerns?
Impact training and joint protection are not in conflict when the program is designed well. We scale every movement to what your body is ready for, and we build strength in the muscles surrounding the joints before increasing load. If you have a specific concern — osteoarthritis, a previous injury, or anything else — tell us before your first session and we will work around it. For most women, doing nothing is the greater risk to joint health long term.
What if I have bad knees?
Start with low-impact progressions and build gradually. Options include marching with intention, low squat jumps with minimal lift, and step-touch patterns. For most women with general knee discomfort, controlled progressive impact training is beneficial, not harmful. Anyone with a specific knee condition or recent injury should check with their physio first.
Do I need to land hard for it to be effective?
No. Landing strong is the goal, not landing hard. The bone-building stimulus comes from the impact itself. Muscles should absorb and control the landing. Soft, controlled landings still generate the ground reaction forces bones need. Crashing down just increases injury risk.
Is jump training appropriate for me if I've never done it before?
Yes, with the right progressions. Start where you are, not where you think you should be. Three to five minutes a few times a week is enough to begin. You build from there.
What types of jumping should I include?
Two-foot jumps, squat jumps, jumping jacks, jump rope, lateral side-to-side jumps, forward and back hops, and single-leg hops. Variety across directions is important.
I've been told to avoid impact because of osteoporosis. Is that still the right advice?
The old advice to avoid impact is increasingly being challenged by current research. For women with osteoporosis, the approach needs to be more gradual and supervised, but the evidence supports progressive loading rather than complete avoidance. Speak with your doctor or physio before starting — but the conversation is worth having, because blanket avoidance is no longer considered best practice.
Do I need to be fit before I start?
No. Legacy is not a gym for people who are already fit — it is a gym for women who want to build fitness in a structured, supported environment. Most members start exactly where you are. Our coaches know how to meet you there and progress you at a pace that works for your body.
I've never done strength training before. Is Legacy right for me?
Yes — and you are exactly who we built this for. Women who are new to strength training often see the most significant changes, because their bodies respond strongly to a well-structured programme. Our coaches teach technique from the ground up. You will never be thrown in and expected to figure it out.
What if I'm post-menopausal rather than perimenopausal?
Everything in this post applies to you. The evidence for strength training and impact exercise protecting bone density is strong across both perimenopause and post-menopause. In some respects, post-menopausal women have the most to gain from starting a consistent strength programme, because oestrogen levels have stabilised and the body responds predictably to progressive training.
How is Legacy different from a regular gym?
Legacy is a boutique coaching studio, not a facility you join and navigate alone. Every session is coached, every programme is structured, and the environment is built specifically for women 35+. You will not be competing for equipment with 22-year-olds or working out next to people who have no idea what they are doing. The community here is genuinely one of the things members talk about most.
How soon will I see results?
Research shows measurable changes in bone mineral density in as little as 16 weeks with consistent practice. You will likely notice other things sooner — energy, sleep, strength, how you feel day to day. Consistency matters more than intensity.
Strong women. Training smart.
Come and see what evidence-based strength training for women 35+ actually looks like.
