Muscle: The Longevity Metric Most People Ignore
And why that needs to change—like, yesterday.
When you think about getting older, what’s the first thing that comes to mind?
For most people, it’s wrinkles, weight gain, or maybe getting a little slower.
But the real story? It’s muscle.
That’s right—your muscle mass might be the most important thing you’re not tracking. And no, we’re not talking about bodybuilder vibes. This is about staying mobile, energetic, and independent for as long as possible.
Let’s break it down.
What Is Muscle Mass (and Why Should You Care)?
Muscle mass is the part of your body made up of lean tissue—the stuff that moves you, supports you, and literally keeps you upright.
As you age, you naturally lose muscle.
This is called sarcopenia, and it starts sneaking up as early as your 30s. If you don’t track and protect your muscle, you could lose up to 30% by your 70s.
That’s not just about strength.
It affects:
How fast your metabolism runs
How steady your balance is
How easy it is to recover from stress, workouts, or injuries
How long you can live on your own
More Muscle = More Life
Strong muscles = strong life. Simple as that.
Want to keep hiking, lifting grandkids, or traveling well into your 70s and 80s?
Want to avoid falls, frailty, or slow recovery from illness?
Then you need to build—and track—your muscle now.
Why the Scale Can’t Help You
You can lose fat AND lose muscle at the same time—and your scale won’t tell you the difference.
In fact, the scale might show weight loss as “good,” even if you’re losing the wrong kind of weight.
This is where DEXA comes in.
How DEXA Scans Help You Track Muscle (The Right Way)
Unlike your bathroom scale or smart watch, a DEXA scan shows you exactly:
How much lean muscle you have
Where your muscle is (arms, legs, core)
How you compare to people your age and sex
If you have any muscle imbalances that might lead to injury
It’s the gold standard for tracking body composition. And it only takes 10–15 minutes.
Real Talk: This Isn’t Just About Looking Good
Muscle is the most powerful anti-aging tool you’ve got.
The science is clear:
People with more lean muscle mass live longer, feel better, and bounce back faster.
And even better—it’s never too late to build it.
