A useful plan should answer both. Exercise can address bone loading, muscle strength and balance, but these are different aims. Understanding the difference makes it easier to review your existing routine without assuming that every hard workout is effective for bone health.
First, understand what the scan has told you
Osteopenia and osteoporosis are terms used in bone health assessment. The meaning of a scan also depends on the sites measured, your age, fracture history and the wider medical picture.
A T score is not an exercise prescription. Two people with the same score may need different starting points because their strength, balance, symptoms or fracture history differ.
Ask your GP or reporting clinician what the result means for your overall fracture risk and medical management. Then bring that information into exercise planning. Our DEXA guide explains the scores in more detail.
Three types of exercise do different jobs
Resistance exercise provides a muscular challenge
Resistance exercise asks muscles to work against a load. The load might come from weights, a machine, a resistance band or body weight. The useful question is whether the selected movement and resistance create an appropriate challenge for the person and the area being trained.
Australian guidance recommends progressive resistance exercise at least twice a week for relevant adults with low bone density. “Progressive” means the exercise is reviewed and adjusted as capacity develops. It does not mean every session must feel harder than the last.
Impact adds a different loading stimulus
Impact involves forces transmitted through the skeleton when the foot contacts the ground. Walking, running and jumping create different loading demands. The appropriate type and level depend on fracture risk, movement control, current capacity and other conditions.
Do not add jumping solely because you have read that impact can benefit bone. It needs to fit your clinical situation and be introduced appropriately.
Balance training addresses falls
Balance work is aimed at controlling your position and responding to a loss of stability. That is a different outcome from improving a bone density measurement.
A Cochrane review found that exercise programs reduced the rate of falls in older people living in the community, with strong evidence for programs involving balance and functional exercise. The finding concerns fall prevention, not proof that a balance exercise increases bone density.
A complete plan may need all three elements, with different amounts of attention given to each.
Where does walking fit?
Walking is useful physical activity and can support a regular routine. It does not usually provide the same bone loading stimulus as appropriately selected resistance and impact exercise.
The practical response is not to stop walking. It is to check whether walking is doing nearly all the work in your program. A person who walks most days may still need a more deliberate strength and balance component.
The same reasoning applies to a routine dominated by cycling or swimming. Those activities can remain valuable, while other exercise addresses the specific demands of bone and falls prevention.
What does “challenging enough” actually mean?
Sweating heavily is not a measure of bone loading. A class can be demanding for the heart and lungs while using very light resistance. Conversely, a strength exercise can be appropriately demanding without leaving you breathless for several minutes.
To review an exercise, record its name, resistance, repetitions, sets and how it feels near the end of a set. Include any symptoms and how the movement is controlled.
For example, “I use the same machine twice a week” leaves several questions unanswered. “I complete the prescribed sets with the same range, the final repetitions require effort, and we review the resistance when they become easier” describes a progression process.
This is not a universal rule for choosing a weight. It is a way to make the exercise dose visible so it can be judged properly.
What the LIFTMOR trial actually found
The Australian LIFTMOR trial enrolled 101 postmenopausal women with low bone mass. Over eight months, the intervention group completed supervised resistance and impact training twice a week in sessions lasting about 30 minutes. The comparison group followed a lower intensity home program.
Average lumbar spine bone density increased by 2.9% in the supervised group, compared with a 1.2% decrease in the comparison group. Physical function also improved. One minor back spasm was reported as a training related adverse event.
The study shows that appropriately screened women could undertake a carefully supervised, challenging program with useful outcomes. It does not establish that everyone with osteoporosis should copy the exercises independently, or that the program has proved a particular reduction in fractures. These were group averages, not promised individual results.
The lesson is not “lift heavy at any cost”. It is that the exercise stimulus, screening, supervision and progression all matter.
How previous fractures change the discussion
A previous spinal fracture or multiple fractures after minor trauma changes the precautions around exercise. The UK “Strong, steady and straight” consensus generally advises limiting impact to the level of brisk walking in these circumstances unless individual guidance supports something different.
Spinal movement and lifting technique also deserve attention. High degrees of forward bending, particularly with added load, may need modification. That is not a reason to tell someone never to bend or to avoid normal movement altogether. It is a reason to teach suitable strategies and choose exercises carefully.
The plan should account for falls risk, joint problems and current symptoms as well as the scan. New severe pain after a fall or concern about a possible fracture needs medical assessment, not a test of how much exercise can be tolerated.
Review your routine with these questions
Scroll to see all columns.
| Part of your week | What to record | What to clarify |
|---|---|---|
| Strength sessions | Exercises, resistance, sets and repetitions. | Is the load appropriate, and how will it progress? |
| Impact activity | What you do and how often. | Does this level suit your fracture history and capacity? |
| Balance work | The task and support used. | Is it useful and appropriately supervised where needed? |
| Walking or other aerobic exercise | Time, effort and consistency. | What benefit is this providing, and what does it leave unaddressed? |
| Symptoms and recovery | Changes during exercise and afterwards. | Which responses require an adjustment or further review? |
Take the record to a practitioner with relevant bone health experience. You do not need to change every part of your program before that discussion.
How do you know it is helping before another scan?
A planned review can look at the resistance you can manage, movement quality, balance tasks, exercise consistency and confidence in everyday activities. These are useful outcomes in their own right, even though they do not prove that bone density has changed.
Repeat scanning should follow the medical plan and be timed when the information can influence care. Small numerical changes need to be judged against the facility’s measurement precision. A short interval and a different number do not automatically demonstrate success or failure.
Exercise also sits alongside nutrition, medication where indicated and review of other fracture risks. It should not be presented as a replacement for prescribed medical treatment.
Your next step
Gather the scan report, relevant fracture history and a record of your current exercise. The most useful question is: “What does this routine already address, what is missing and what can be progressed safely?”
The initial Clinical Exercise Assessment can help establish the exercise component of that plan. Private fees and funded pathways are explained separately on the fees and funding page.
