At BeFit Training Physiotherapy in Edgecliff and Coogee, we work with patients across Sydney to develop exercise programmes that support bone health and reduce long-term fracture risk. This guide explains what bone mineral density is, how exercise influences it, and what a supervised physio programme for bone density involves.
What Is Bone Mineral Density?
Bone mineral density refers to the concentration of minerals, primarily calcium, contained within bone tissue. Higher bone mineral density generally means stronger bones that are better able to tolerate everyday stresses and impacts.
As we age, bone density gradually declines, which is a normal part of the ageing process to a degree. However, this process can accelerate in certain groups, including post-menopausal women, people with a family history of osteoporosis or osteopenia, those with a history of bone stress injuries or fractures, and people with dietary deficiencies that affect calcium and vitamin D absorption.
If bone density drops below a certain threshold it may lead to osteopenia or osteoporosis, both of which increase the risk of fractures. Importantly, bones remain responsive to loading throughout life, which means bone density is modifiable at almost any age with the right approach.
How to Improve Bone Density Through Exercise
Bones, like muscles, adapt to the forces placed upon them. When a muscle contracts, load is applied to the skeleton, and the body responds by remodelling the bone to handle similar stress in future. This is known as bone remodelling.
When loading is insufficient, bones receive less stimulus to maintain their density and strength, which is one reason sedentary lifestyles contribute to reduced bone density over time. Because the process is gradual, it often goes undetected until a fracture or scan reveals the extent of the change. Our guide on why exercise is the key to better bone density goes deeper into the mechanism.
The types of exercise most beneficial for bone density are resistance training, weight-bearing exercise and impact-based activity. Many people, particularly in older age groups, assume these are unsafe and prefer lower-impact activities such as swimming or cycling. While these are valuable for cardiovascular health, they provide minimal stimulus to bone and are not effective tools for improving or maintaining bone mineral density. A well-designed programme that includes appropriate loading is both safe and significantly more effective for bone health when supervised correctly.
What a Supervised Physio Programme Involves
Exercise is important for bone health, but the type, intensity and progression of loading are critical, particularly for those starting out or already diagnosed with low bone density. Applied incorrectly, loading can increase injury risk rather than reduce it. This is where a supervised physio programme makes a meaningful difference.
At BeFit Training Physiotherapy in Edgecliff, our physiotherapy team assesses strength, mobility, balance and movement patterns before designing an exercise programme tailored to the individual’s needs, history and current fitness level. Programmes aimed at improving bone health typically focus on:
- Progressive resistance training to load the skeleton appropriately
- Impact training introduced gradually to stimulate bone remodelling
- Balance training to reduce fall risk
- Movement safety to protect joints under load
- Strategies to prevent or reverse deconditioning
Building this kind of loading safely is exactly what our strength and conditioning service is designed to support. If you have already been diagnosed, our guide on building stronger bones with osteoporosis physiotherapy covers the supervised approach in more detail.
The ONERO Programme for Osteoporosis and Osteopenia
For patients already diagnosed with osteopenia or osteoporosis, our ONERO programme at Edgecliff is specifically designed for this population. ONERO is an evidence-based bone health and strength programme that follows a structured, progressive protocol of resistance and impact training, supported by clinical research in osteoporosis management.
Part of what makes it effective is the emphasis on power and high-intensity loading. Our article on power training for osteoporosis explains why this matters for bone.
DEXA Scanning to Track Bone Density
DEXA scanning is available at our Edgecliff clinic, providing an objective measure of bone mineral density, lean mass and body composition. For anyone managing or monitoring bone health, a DEXA scan provides a clear baseline and allows progress to be tracked over time.
How to Get Started
One of the most important factors in improving bone health is consistency over time. Small amounts of targeted loading performed regularly can have meaningful long-term benefits, far more than occasional high-intensity effort.
Starting with an assessment helps ensure that exercise is both appropriate and safe for your current presentation, and that progression is managed in a way that builds bone density without increasing injury risk. No referral is required to book an initial assessment.
Frequently Asked Questions
Can exercise really improve bone density?
Yes. Research consistently shows that weight-bearing and resistance exercise can maintain and, in some cases, improve bone mineral density. The stimulus comes from the mechanical load placed on bone during exercise, which triggers bone remodelling. The type and intensity of exercise matters, as not all activity is equally effective for bone health.
Is a supervised physio programme safe if I have osteoporosis?
Yes, with appropriate supervision and programme design. Evidence supports resistance training as safe and effective for people with osteoporosis when it is correctly prescribed and progressed. The key is starting at an appropriate load, progressing gradually, and prioritising movement quality throughout. A supervised physio programme provides the oversight needed to make this safe.
What is the ONERO programme?
ONERO is an evidence-based exercise programme designed for people with osteoporosis or osteopenia. It follows a structured protocol of high-intensity resistance and impact training shown in clinical research to improve bone density and reduce fracture risk. It is available at BeFit’s Edgecliff clinic and supervised by physiotherapists trained in its delivery.
What is a DEXA scan and do I need one?
A DEXA scan measures bone mineral density, lean mass and body composition with a low-dose X-ray. It is the standard tool for assessing bone health and is used to diagnose osteopenia and osteoporosis. For anyone managing bone health or considering a structured programme, it provides an objective baseline and allows progress to be monitored. DEXA scanning is available at BeFit’s Edgecliff clinic.
How often should I exercise for bone health?
Current evidence generally supports two to three sessions of resistance and impact training per week for bone health benefits. Consistency over months and years matters more than any single session. Your physiotherapist will design a programme with an appropriate frequency and progression based on your starting point and goals.
