The exercises that most effectively build and maintain bone density share a common feature: they place mechanical load on the skeleton. The greater the load, and the more varied the direction of that load, the stronger the stimulus for bone formation. This principle guides everything that follows.

CALLOUT: The skeleton responds to forces it is not used to. Familiar movements, done at the same intensity for years, produce a diminishing stimulus for bone adaptation over time. Variety, progression, and appropriate challenge are what keep bone responding.

Weight-bearing exercise

Weight-bearing exercise is any activity performed on your feet, against gravity. It is the foundation of bone health exercise because it places direct load through the spine and lower limbs, the sites most commonly affected by osteoporosis.

The most accessible forms of weight-bearing exercise include:

  • Walking, particularly brisk walking or walking on varied terrain and inclines
  • Hiking and trail walking, which adds balance challenges and greater muscular demand
  • Dancing, which combines impact, variety of movement, and balance in a form that many women find genuinely enjoyable
  • Stair climbing, which places significant load through the hip and lower limb
  • Aerobics and step classes, which provide varied impact through the lower skeleton

Research supports walking as a meaningful contributor to maintaining bone density, though studies consistently show it is more effective at slowing loss than at producing gains. For women with osteoporosis who want to improve density rather than simply maintain it, walking alone is not sufficient.

CALLOUT: Walking is an excellent starting point and an important component of an active lifestyle. But for women with osteoporosis who want to actively improve bone density rather than simply slow its decline, resistance training and higher-impact activities need to be part of the picture too.

Resistance training

Resistance training, also called strength training, involves working muscles against an external load. It is one of the most effective exercise modalities for bone health in post-menopausal women and is supported by the strongest body of evidence.

When muscles contract forcefully against resistance, they pull on the bones to which they are attached, creating a mechanical stimulus for bone formation at precisely the sites most relevant to osteoporosis: the hip, spine, and wrist.

Effective forms of resistance training for bone health include:

  • Free weights such as dumbbells and barbells
  • Resistance bands
  • Weight machines
  • Bodyweight exercises performed with sufficient challenge, such as squats, lunges, step-ups, and push-ups
  • Any activity that requires muscles to work against a meaningful load

QUOTE: "The key word in resistance training for bone health is progressive. Starting light is sensible, but staying light indefinitely produces a diminishing stimulus. As the body adapts, the challenge needs to increase, gradually and safely, for bone to continue responding."

A 2017 meta-analysis of resistance training in post-menopausal women found significant improvements in femoral neck bone density with programmes performed two to three times per week over six to twelve months. The effect was greatest when training was supervised and progressively loaded.

Impact exercise

Impact exercise involves activities where the feet leave the ground and return to it, creating ground reaction forces that travel through the skeleton. These forces are among the most potent stimuli for bone formation.

Examples of impact exercise appropriate for many women with osteoporosis include:

  • Jogging or running, which generates impact forces of two to three times body weight
  • Jumping and hopping exercises, which generate even higher impact forces and have been shown to be particularly effective at the hip
  • Skipping
  • Court sports such as tennis, badminton, and pickleball

Research on impact exercise in post-menopausal women is striking. A 2015 study found that simple hopping exercises performed daily for twelve weeks produced significant increases in hip bone density in pre-menopausal women, and follow-up research has explored similar approaches in post-menopausal women with promising results.

CALLOUT: Impact exercise is not appropriate for all women with osteoporosis, particularly those with severe bone loss or a history of vertebral fractures. The exercises that follow in this section should be discussed with your doctor or physiotherapist before you begin, particularly if your T-score is below -2.5 at the spine or hip.

Balance and coordination training

Balance training does not build bone directly, but it addresses the other side of the fracture equation: fall risk. Activities that challenge balance and coordination improve the body's ability to detect and respond to instability, reducing the likelihood of a fall.

Effective balance training includes:

  • Tai chi, which has one of the strongest evidence bases of any activity for fall prevention in older adults, with multiple studies showing reductions in fall rate of 20 to 45 percent
  • Yoga, particularly styles that emphasise stability, hip strength, and body awareness
  • Single-leg standing exercises
  • Walking on varied or uneven surfaces
  • Activities that require rapid changes of direction

A 2012 Cochrane review of fall prevention interventions found that balance and functional exercise programmes were among the most effective strategies for reducing fall rates in older adults living independently.

CALLOUT: Tai chi has been studied more extensively for fall prevention in older adults than almost any other exercise modality. The evidence is consistent and compelling. If you are looking for one activity to add specifically for fall prevention, the research points clearly in this direction.

Combining exercise types for maximum benefit

The most effective exercise programme for bone health combines all three approaches: weight-bearing, resistance, and balance training. Research consistently shows that combined programmes produce greater bone density benefits than any single modality alone.

A practical weekly structure might include:

  • Two to three sessions of resistance training targeting the major muscle groups of the lower body, upper body, and core
  • Daily or near-daily weight-bearing activity such as walking, dancing, or stair climbing
  • Two to three sessions of balance and coordination work, which can be incorporated into other activities or done independently

The specific exercises, their order, their load, and their progression should ideally be guided by a physiotherapist or exercise physiologist with experience in osteoporosis, at least initially.
