You’ve probably never thought of your muscles as an “organ.” But new science shows that muscle functions like an endocrine organ—producing hormones, regulating inflammation, and playing a central role in healthy aging.
As a woman over 60 and a personal trainer, I can tell you firsthand: maintaining muscle isn’t about vanity or lifting heavy weights. It’s about staying independent, strong, and youthful—not just in how we look, but how we live.
Why Muscle Matters More After 50
After age 30, we lose up to 3–8% of muscle mass per decade, and that rate speeds up after 60. This process—called sarcopenia—can sneak up on you, even if your weight stays the same. You might feel weaker, more tired, or even less steady on your feet.
But here’s the good news: muscle is incredibly adaptable. With the right type of movement and enough protein, we can build and maintain it well into our 70s, 80s, and beyond.
In fact, research published by Srikanthan & Karlamangla found that higher muscle mass in older adults was associated with a significantly lower risk of mortality—independent of body fat.
Another review published by Schnyder and Handschin described skeletal muscle as an endocrine organ that secretes myokines—a “metabolic reservoir” protecting against insulin resistance, inflammation, and frailty.
Muscle Is More Than Strength
Here’s what makes muscle so fascinating—and vital:
- Muscle releases myokines, signaling molecules with hormone-like effects that support brain health, reduce inflammation, and boost immune function.
- Muscle helps regulate blood sugar, burn fat, and prevent type 2 diabetes.
- Stronger muscles mean better balance, fewer falls, quicker recovery after illness, and more years doing what you love.
As someone who trains older adults, I’ve seen transformative changes—not just physically, but mentally—when muscle becomes part of the plan. Confidence rises. Posture improves. Energy renews.
What You Can Do Starting Today
You don’t need to become a bodybuilder to build muscle. But consistency is key. Here are a few strategies I follow—and recommend to my clients:
- Prioritize resistance training 2–3 times per week (using bodyweight, resistance bands, or free weights)
- Eat sufficient protein—approximately 1.0–1.2 g per kg of body weight per day
- Walk daily to stay moving and support recovery
- Prioritize rest—muscle builds during sleep, not just training
From My Life to Yours
I want to age with strength—not just for me, but for my five grandkids. I want to carry groceries, pick up toddlers, hike with friends, and keep showing up for my clients and my family with vitality.
So yes, muscle is more than just tissue. It’s an investment. It’s your organ of longevity—and it’s never too late to start building it.
