Is resistance training good for fragile bones? 

Resistance training, often called strength training, is not only good for fragile bones, it is frequently a cornerstone of the medical advice given to those with osteoporosis in the UK. While the idea of lifting weights or using resistance bands might seem risky when bones are thin, the opposite is true. When performed correctly and with the right modifications, resistance training provides a powerful stimulus that encourages bones to maintain their density. Furthermore, it strengthens the muscles that surround and protect the skeleton, acting as a “shock absorber” that can prevent a fall from turning into a life-altering fracture.

Resistance training pulls on the bone to stimulate growth. 

The primary benefit of resistance training comes from the way muscles attach to the skeleton. When you lift a weight or pull against a resistance band, your muscles contract and pull on the tendons. These tendons are attached to the bone, and this pulling force creates a mechanical “tug” on the bone tissue. 

This tugging sensation is detected by bone-building cells called osteoblasts. In response to the regular challenge of resistance training, these cells are stimulated to produce more bone matrix, helping to slow down the thinning process associated with fragile bones. According to the Royal Osteoporosis Society, strengthening the muscles also improves “proprioception”, your body’s awareness of its position, which is vital for maintaining balance and preventing trips. 

Strength training acts as a natural “back brace” for the spine. 

One of the greatest risks for people with fragile bones is a vertebral compression fracture in the spine. Resistance training that focuses on the “posterior chain”, the muscles in your back, glutes, and hamstrings, can help mitigate this risk. 

By strengthening the muscles that run along the spine (the erector spinae), you create a natural support system that helps keep you upright. This improved posture reduces the uneven pressure on the front of your vertebrae, which is where most fractures occur. The NHS recommends that older adults and those with bone thinning focus on these functional movements to maintain their height and prevent the “stoop” often associated with osteoporosis. 

The principle of “progressive loading” ensures safety. 

The key to exercising safely with fragile bones is a concept called progressive loading. This means starting with very light weights, or even just your own body weight, and very slowly increasing the resistance over many weeks and months as your body adapts. 

In a UK clinical setting, a physiotherapist or specialist trainer will ensure that: 

• Form is prioritised: Moving slowly and with control is more important than the amount of weight lifted. 

• Repetition ranges are safe: Typically, performing 8 to 12 repetitions of an exercise with a moderate weight is safer for fragile bones than trying to lift a very heavy weight for only 1 or 2 repetitions. 

• Rest is scheduled: Bones need time to recover and strengthen between sessions, so a gap of 48 hours between resistance workouts is usually advised. 

Which exercises are best and which should be modified? 

Not all strength exercises are appropriate for someone with a high risk of fracture. In the UK, the NICE guidelines emphasise a tailored approach: 

• Recommended: Squats (holding a chair for balance if needed), wall push-ups, seated rows, and leg presses. These strengthen the hips, legs, and upper body without putting excessive strain on the spine. 

• Avoid or Modify: Deep forward folds with weights, heavy “deadlifts” with a rounded back, or abdominal crunches. These movements can put too much pressure on the front of the vertebrae. 

• Focus on the Wrist: For many, the wrist is a common site for fractures. Simple resistance exercises using light dumbbells or squeezing a stress ball can help improve the density of the forearm bones. 

Finding a bone-safe programme in the UK. 

If you are concerned about starting resistance training on your own, there are several ways to get professional support through the NHS or local community: 

1. GP Referral: Many UK surgeries can refer you to an “Exercise on Referral” scheme, where a qualified instructor creates a programme specifically for your medical needs. 

2. Physiotherapy: If you have already had a fracture, a physiotherapist can provide a targeted set of exercises to help you rebuild safely. 

3. Tiered Classes: Look for classes labelled “Falls Prevention” or “Strong Bones,” which are specifically designed for older adults or those with osteoporosis. 

Conclusion 

Resistance training is highly beneficial for fragile bones, as it stimulates bone-building cells and creates a protective “muscular shield” around the skeleton. By following the principle of progressive loading and focusing on safe, controlled movements, individuals with osteoporosis can significantly improve their stability and reduce their risk of future fractures. While it may feel daunting to start, the long-term benefits for your independence and mobility are immense. If you are concerned about starting a new resistance routine, seek a medical review. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
