Why 'Wear and Tear' Is the Wrong Way to Think About Aging Joints

The phrase "wear and tear" treats a joint like a part that grinds down until it fails. Joints are living tissue. They respond to load, rest and movement, and they change over a lifetime.

Joints and the tissues around them do change as we age, and that is normal. But change is not the same as destiny. People of the same age often have very different shoulder function, and that gap is a clue. Something other than age alone is shaping how the shoulder moves and feels.

Muscle is a good example. Losing muscle with age is common. The Australian and New Zealand sarcopenia guidelines note that it is not inevitable, and that resistance exercise is the first-line approach [R08]. The muscles that steady your shoulder are part of that picture.

• Resistance training helps older adults counter losses in muscle strength and mass, and it supports function, mobility, independence and quality of life [R06].
• WHO guidelines recommend muscle-strengthening activity on at least two days a week for adults. Adults 65 and over should also do multicomponent activity that emphasises balance and strength on at least three days a week [R07]. The same guidance says that every move counts.
• A 2026 review linked strength, mobility, body composition and posture with shoulder pain and disability in adults 60 and over [R28]. These are modifiable targets. The evidence for forward head posture in older adults, however, is limited and indirect.

These are associations. They show that factors travel together with shoulder pain. They do not prove that any one factor causes it, and they do not mean that age alone sets your outcome.

1. Change the goal. Instead of "protect what I have," think "keep building what I need." That shift makes it easier to choose movement that helps.
2. Move a little every day. Gentle, pain-free movement counts, and it does not need to be long. Seated shoulder rolls and slow arm reaches are a good place to start.
3. Build strength two or more days a week, once cleared. Use a load you can control with good form. A seated option is to sit tall and do slow, controlled rows or presses with light resistance, such as a towel or a light band.
4. Work on range gradually. Move within a comfortable range and increase it slowly over weeks. Stop short of sharp pain.
5. Add balance if you are 65 or older. Stand near a counter you can hold, and practise slow weight shifts. This supports the balance element that WHO guidance highlights [R07].
6. Check in when things change. If pain is getting worse, or your range is shrinking, book a clinician visit rather than pushing through.
