When you think of “muscle” you probably see visions of big biceps on athletes or superheroes.

But did you know “muscle” is also what lets you stand up out of a chair? And keeps you from falling?  It’s what gives you the ability to do – oh, just about any activity, from putting away groceries to playing with children.

In short, “muscle” is absolutely fundamental to our everyday existence.

But here’s another fact that most people don’t realize. We all start to lose muscle on a regular, ongoing basis beginning in our 30s – unless we practice strength or resistance training. There’s even a medical term for it: sarcopenia.

It’s the perfect example of the old saying, “Use it or lose it.”

Just look at frailty and weakness that often slow down older people. Have you ever teared up watching a grandparent struggle to get off the couch? It’s common to think that’s just a normal part of getting older.

But it is not inevitable. And, I believe, it is not acceptable, especially when the solution is so clear and accessible.

The more you engage in resistance training, whether with bands, weights, or your own body weight, the more you preserve and strengthen your muscles. And no, it won’t make you bulky. Instead, it enhances your strength, flexibility, and overall well-being.

Strength training is essential for everyone who wants to maintain vitality and independence throughout life, and this is becoming increasingly known in the general, younger public.

Dr. Peter Attia, in his bestselling book “Outlive: The Science and Art of Longevity,” says you should think of strength training as your retirement savings plan for your muscles. Just as you want financial security in your later years, you also want enough strength to support your active lifestyle and protect against age-related decline.

The earlier you start, the better off you’ll be.

There’s no time like the present.
