Exercise and Bone Health: How Strength, Impact, and Movement Improve Bone Density for Life

Exercise plays an important role in maintaining bone health and supporting our bodies as we get older.  While many people associate exercise with improved fitness or muscle strength, regular physical activity is one of the most important factors that impacts your bone density, bone mass and long-term bone health. A well-rounded exercise routine that includes a mix of exercise types, including strength and resistance training, is key to maintaining bone strength, reducing falls and fracture risk, and supporting long-term independence. 

Bones are living tissue, and like muscles, they respond to how we use our bodies. When we move regularly and place health stress on our bones, they are more likely to stay strong. When we move very little, bones can gradually lose strength over time, increasing the risk of fractures and conditions, including osteoporosis. Although a decrease in bone density is a natural process that happens with ageing, it is important to keep moving to slow down these decreases. 

What is bone density and why does exercise matter? 

Bone density refers to how strong your bones are and how well bones can cope with daily activities and impacts. Strong bones are better at handling everyday tasks including walking, lifting and catching yourself when you stumble. Weaker bones are more likely to break from a fall or at times sudden movement. 

As we age, it is common for bones to slowly lose strength. This often happens without any clear signs at first. A bone density scan, the most common called a DEXA, is a test that indicates how strong your bones are and whether any bone loss has begun. A significant loss of bone strength may indicate osteoporosis. 

Some people with osteoporosis notice changes such as back pain, a change in posture or becoming shorter, while others may not notice anything until they experience a fracture. 

How exercise helps support bone health 

Exercise keeps bones strong by applying safe, controlled stress that encourages them to maintain their strength. Using a variety of movements helps target different bones and supports overall bone health. Exercise also helps increase bone mass, which improves overall skeletal strength.

Strength and resistance exercises 

Resistance or strength exercises involve working muscles against weight or another resistance, such as dumbbells, machines, resistance bands or body weight. When muscles contract, they place controlled stress on the bones they attach to. This stress signals the bones to maintain or increase their strength, which is particularly important for reducing bone loss as we age. Resistance exercises also improve muscle strength, making everyday movements safer and more stable. 

 

Weight-bearing activities 

Weight-bearing exercises are activities where your bones and muscles support your body weight. Examples include walking, climbing stairs, hiking or jogging. These activities also create stress on the bones in your legs, hips and spine, which helps maintain bone density and overall skeletal strength. Regular weight-bearing activities also support balance, endurance and cardiovascular health. 

Balance and stability exercises 

Balance and stability exercises focus on improving coordination, posture and your body’s ability to balance and react to changes in movement. Although they don’t have a significant impact on bone strength itself, these exercises, including standing on one leg, heel-toe walking, or functional movements, help reduce the risk of falls. For people with low bone mineral density or osteoporosis, balance and stability is essential in preventing falls and fractures, as well as maintaining confidence in daily activities.  

Movement and joint health 

Maintaining joint movement and flexibility allows bones and muscles to work together effectively. Gentle stretching, mobility exercises and functional movement activities keep your joints comfortable and reduce stiffness, making it easier to participate in other forms of exercise consistently. Healthy joints also help ensure that bone-strengthening exercises are performed safely and effectively. 

Exercise and osteoporosis 

Exercise has been found to be one of the most effective ways to improve and maintain bone mineral density. For people with low bone density, including osteoporosis and osteopenia, it is important that exercises are tailored to an individual’s capacity and are progressed appropriately over time. This helps ensure exercises are safe and effective. With the right guidance, exercise for osteoporosis can help maintain bone strength, improve balance, and support confidence with movement.

The wider benefits of staying active 

Regular exercise benefits more than just bones. It helps improve muscle strength, supports better balance, improves sleep, lifts mood and helps maintain heart and metabolic health. Together, these benefits make everyday activities easier to help people stay independent longer and to continue doing what they love. 

Working with a clinical exercise physiologist to improve bone health 

Certified clinical exercise physiologists are trained to help people exercise safely, whether they have never exercised before, have concerns about their health, have any medical considerations, or if they’re a seasoned professionals in the gym. They take the time to understand your medical history, physical capacity and movement, and goals before creating a program and weekly routine that works for you. 

Programs are designed to be safe, achievable and progressive, helping you build confidence as well as strength. 

Take the next step toward stronger bones 

If you are concerned about bone strength, looking for osteoporosis treatment or want to feel steadier on your feet as you age, exercise can play an important role. With the right support, exercise can be safe, effective and enjoyable. 

Our exercise physiologists work with older adults to improve strength, balance and bone health in a supportive and structured way. Call us today to book an initial consultation and take a positive step toward protecting your bones and maintaining your independence.
