Osteoporosis and osteoarthritis are two of the most common musculoskeletal conditions, particularly as we age. Alongside these, many people are also diagnosed with osteopenia—often considered a “warning stage” before osteoporosis develops.
While these conditions affect the body differently, strength training is one of the most effective, evidence-based strategies to manage all three. With the right approach, resistance exercise can strengthen bones, support joints, reduce pain, and improve overall function and independence.
Understanding the conditions
Osteoporosis is characterised by significantly reduced bone density and deterioration of bone tissue, increasing the risk of fractures—especially in the hips, spine, and wrists.
Osteopenia is a milder reduction in bone density. It doesn’t carry the same immediate fracture risk as osteoporosis but indicates that bone strength is declining. Importantly, osteopenia is reversible or manageable, making early intervention through exercise critical.
Osteoarthritis is a degenerative joint condition where cartilage wears down over time. This can lead to joint pain, stiffness, swelling, and reduced mobility—commonly affecting the knees, hips, hands, and spine.
It’s not uncommon for individuals to experience both reduced bone density (osteopenia/osteoporosis) and osteoarthritis at the same time, which is where targeted exercise becomes especially valuable.
how strength training helps
- Builds and Maintains Bone Density
Bones respond to load. When you perform resistance training, muscles pull on bone, stimulating it to become stronger. This is particularly important for individuals with osteopenia, where early intervention can slow or even prevent progression to osteoporosis.
- Supports and Protects Joints
Stronger muscles reduce the load placed directly on joints. For individuals with osteoarthritis, this means less joint stress, improved stability, and better movement quality.
- Reduces Pain and Improves Function
Well-structured strength programs have been shown to reduce pain associated with osteoarthritis and improve the ability to perform daily activities such as walking, climbing stairs, and getting up from a chair.
- Improves Balance and Reduces Falls Risk
For those with osteopenia or osteoporosis, preventing falls is critical. Strength training enhances balance, coordination, and confidence, helping to reduce the risk of fractures.
the role of an Exercise Physiologist
Managing these conditions isn’t just about exercising—it’s about exercising correctly.
An Accredited Exercise Physiologist can:
- Assess joint function, and movement capacity
- Identify risks such as falls or joint overload
- Develop an individualised, evidence-based program
- Progress training safely over time
This ensures that exercise is not only effective but also safe and sustainable long term.
why early action matters
Osteopenia is often overlooked because it doesn’t always present symptoms. However, it represents a critical window of opportunity.
By starting strength training early:
- Bone loss can be slowed or stabilised
- Progression to osteoporosis may be prevented
- Long-term function and independence can be preserved
Whether you’re managing osteoarthritis, osteopenia, or osteoporosis, avoiding movement is often the least effective approach. With the right guidance, strength training becomes a powerful tool to support bone health, protect joints, and maintain quality of life.
By taking action early, supervised strength training can make a significant difference not just in managing symptoms, but in long-term health outcomes and independence.
