Should people with osteoporosis avoid high-impact activities? 

In the UK, the advice regarding high-impact activities for people with osteoporosis has evolved significantly in recent years. While it was once common to advise anyone with thin bones to avoid jumping or running, modern clinical guidance from the Royal Osteoporosis Society and the NHS takes a more nuanced approach. For some, high-impact movement is the best way to stimulate bone growth; for others, the risk of a fracture outweighs the potential benefits. The decision depends on the severity of your bone thinning, your history of fractures, and your overall physical fitness.

High-impact activity provides the strongest signal for bone building. 

High-impact activities are those where both feet leave the ground at the same time, such as running, skipping, or jumping. Every time you land, the force of the impact travels through your skeleton. This force provides a powerful “loading” signal to the bone-building cells (osteoblasts), encouraging them to deposit more minerals and strengthen the bone matrix. 

For many people with osteopenia (the precursor to osteoporosis), high-impact exercise is a vital tool to stop further thinning. In these cases, the bones are still strong enough to handle the stress, and the resulting increase in density can help prevent a future diagnosis of osteoporosis. 

When should you avoid high-impact activities? 

While impact is good for building bone, it can be dangerous if the bones are already very fragile. You should generally avoid high-impact activities if: 

• You have had a spinal fracture: The force of landing from a jump can put too much pressure on the vertebrae, potentially causing further collapse. 

• Your T-score is lower than -3.0: Very low bone density means the “architectural” strength of the bone is significantly compromised. 

• You have multiple risk factors for falls: Such as poor balance, dizzy spells, or advanced frailty. 

• You have severe joint issues: Such as advanced osteoarthritis in the hips or knees, where the impact could cause significant pain or joint damage. 

According to NICE guidelines, if you fall into these categories, the focus should shift to low-impact weight-bearing exercises and resistance training, which provide similar benefits with much lower risk. 

“Moderate Impact” is often the safest starting point. 

For many UK patients who are in the middle, having osteoporosis but no previous fractures, a moderate-impact approach is often recommended. This involves activities that provide some stomp or thud without the high force of a full jump. 

Examples of moderate-impact activities include: 

• Brisk walking or marching: Particularly with a purposeful “stomp” to the step. 

• Low-intensity aerobics: Where one foot usually stays on the ground. 

• Stair climbing: Which provides a consistent, controlled load on the hips. 

• Heel drops: Standing on your toes and dropping onto your heels (a common clinical recommendation for building hip density). 

The 2026 UK “Strong Bones” consensus on impact levels. 

The latest UK consensus for exercise and osteoporosis suggests that most people, even those with a high fracture risk, can and should perform some form of impact. The key is to find the “Right Dose” for your skeleton. 

• Low Risk: Can safely perform high-impact moves (running, jumping). 

• Medium Risk: Should focus on moderate impact and resistance training. 

• High Risk (Previous Fractures): Should stick to low-impact weight-bearing (walking) and focus heavily on balance and strength. 

The NHS emphasises that “some is better than none,” and avoiding all activity out of fear can actually lead to faster bone loss and muscle weakness, making a fracture more likely in the long run. 

How to safely introduce impact into your routine. 

If you have osteoporosis and want to start high or moderate-impact exercise, you should follow a “Start Low, Go Slow” approach: 

1. Get a professional review: Speak to your GP or a physiotherapist who can assess your fracture risk based on your latest DEXA scan. 

2. Focus on footwear: Ensure you have high-quality, cushioned trainers to absorb some of the shock. 

3. Start on soft surfaces: Marching or jogging on grass or a carpeted floor is gentler than on concrete. 

4. Listen to your body: If an activity causes sharp bone pain or lasting joint discomfort, it is a sign that the impact level may be too high for your current strength. 

Conclusion 

Whether you should avoid high-impact activities depends on your individual fracture risk. While high-impact exercise is the most effective way to build bone density, it is not appropriate for everyone, especially those with a history of spinal fractures or very low T-scores. For most people with osteoporosis, a tailored approach involving moderate-impact movement and strength training offers the best balance of safety and skeletal improvement. In the UK, the clinical shift is away from “avoiding impact” toward “finding the safe level of impact” for every patient. If you are concerned about your risk level, seek a medical review. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
