Osteoporosis

Not all exercise builds bone. The right type, at the right intensity, prescribed correctly — does. An Accredited Exercise Physiologist designs programs that measurably improve bone mineral density and reduce fracture risk.

What Is Osteoporosis?

Bone is not inert tissue. It is continuously remodelled throughout life — broken down by osteoclasts and rebuilt by osteoblasts — in a process that is responsive to mechanical loading, hormonal signals, nutritional status, and age. Peak bone mass is typically reached in the late twenties; after that, the balance gradually shifts toward resorption, particularly in postmenopausal women following the decline in oestrogen.

Osteoporosis is defined by a bone mineral density (BMD) T-score of −2.5 standard deviations or below, measured by DEXA scan. Osteopenia sits between −1.0 and −2.5 SD — reduced bone mass that has not yet crossed the diagnostic threshold for osteoporosis but carries meaningful fracture risk, particularly at the hip, lumbar spine, and distal radius (wrist). Together these conditions affect a substantial proportion of older Australians — and because bone loss is silent, many people are unaware of their status until a fracture occurs.

Fractures in the context of osteoporosis carry consequences well beyond the fracture itself. Hip fractures in particular are associated with significant mortality, prolonged hospitalisation, and permanent loss of independence. Vertebral fractures cause chronic back pain, height loss, and postural changes that have their own functional and quality-of-life implications. Reducing fracture risk — through both improving bone density and preventing falls — is the clinical priority.

How Exercise Physiology Helps

Wolff’s Law — the principle that bone adapts to the mechanical loads placed upon it — is the foundation of exercise-based osteoporosis management. When bone is loaded beyond its habitual threshold, osteoblast activity is stimulated and new bone is laid down. The key insight is that not all exercise achieves this. Swimming and cycling, often recommended for joint protection in older adults, produce minimal bone-loading stimulus. The exercise types that drive bone adaptation are those that generate high mechanical forces: progressive resistance training and impact activities.

The LIFTMOR trial (Watson et al., 2018) demonstrated that high-intensity, supervised progressive resistance training — including deadlifts, overhead press, and back squats performed at 80–85% of one-repetition maximum — produced significant improvements in BMD at the lumbar spine and femoral neck in postmenopausal women with low bone density, along with improvements in strength, posture, and functional balance. Critically, this was achieved safely, with no fractures occurring in the exercise group. The results challenged the assumption that high-load training is dangerous in this population — it is not, when prescribed and supervised correctly.

Alongside bone-loading exercise, balance and coordination training is essential. Falls are the precipitating event for the majority of osteoporotic fractures — and fall risk is a modifiable variable. Programs that combine strength, balance, and functional movement training produce substantial reductions in fall incidence. Both arms of the intervention — bone loading and fall prevention — are required for comprehensive fracture risk reduction.

What to Expect

The initial consultation reviews your DEXA scan results, fracture risk assessment (including clinical risk factors beyond BMD), medication history, and current activity level. From there, a program is built targeting the primary fracture sites — lumbar spine and hip — with progressive resistance exercise, impact activity where appropriate, and balance training integrated throughout.

Progression is monitored carefully. Load is increased progressively as strength improves, but always within a framework that manages fracture risk at every stage. The goal is to challenge the skeleton enough to stimulate adaptation — and to do so safely, with the clinical knowledge to make that distinction reliably.

• Review of DEXA scan results and fracture risk assessment
• Progressive resistance training targeting spine and hip (primary fracture sites)
• Impact and weight-bearing exercises to stimulate bone formation
• Balance and coordination training to reduce fall risk
• Safe progression — monitored carefully to manage fracture risk throughout

Is Exercise Physiology Right for You?

If you have a diagnosis of osteopenia or osteoporosis, a family history of fragility fractures, or risk factors for reduced bone density — including long-term corticosteroid use, early menopause, or a history of low-impact fractures — exercise physiology provides the most effective non-pharmacological intervention available for bone health. It works alongside, not instead of, appropriate medical management. No referral is required to book a consultation.
