Most golfers notice, at some point, that their body doesn't turn quite the way it used to. That's a common and well-documented pattern, and it's worth understanding generally why it happens.
What Changes in the Body Over Time
Several gradual changes contribute to reduced flexibility as people age. Connective tissue — tendons and ligaments — tends to become stiffer over time. Tissues can also hold less water and elasticity than they did at a younger age. On top of that, general activity levels often decrease with age, which compounds the effect, since joints that move less tend to become less mobile.
It's Not the Same for Everyone
How much flexibility changes, and how quickly, varies a great deal from person to person. Genetics, activity history, and overall lifestyle all play a role, which is why some older golfers maintain a fuller turn than some younger ones.
Can You Slow It Down?
Generally, yes. Consistent stretching and strength work can help maintain range of motion at nearly any age, even if it takes more deliberate effort than it once did. As covered in What Does the Research Say About Stretching and Mobility?, mobility depends on both flexibility and strength working together, not flexibility alone.
Why This Matters for Golfers
The golf swing depends on rotation through the hips, spine, and shoulders. Maintaining mobility in those areas can help you keep swinging comfortably as you age — that's a reasonable, evidence-aligned expectation. It is not the same as a guarantee of more distance or a lower score, which depend on far more than mobility alone.
Flexibility naturally shifts with age, but how much it changes — and how much of that is preventable — varies by person and by effort.
