Stay Strong, Live Long: Why Muscle Matters as You Age

We all want to live longer—but let’s be honest, what’s the point if we’re not feeling great along the way? The real goal isn’t just adding years to our lives but making sure those years are full of energy, strength, and independence.

Lifespan vs. Healthspan: What’s the Difference?

Over the past century, science and medicine have worked wonders. Thanks to advances in sanitation, public health, and nutrition, people are living much longer. In Canada, for example, life expectancy has jumped to 81.6 years—an incredible 24.5-year increase since 1921! And by 2050, the number of people aged 85 and older is expected to triple.

But here’s the catch: living longer doesn’t necessarily mean living well. That’s where healthspan comes in. Lifespan is how long we live; healthspan is how long we stay healthy and active. Unfortunately, many people spend their later years dealing with health issues, making it crucial to bring these two as close together as possible.

Why Muscle Matters for Healthy Aging

One of the biggest challenges of aging is muscle loss, known as sarcopenia. Losing muscle can lead to weakness, loss of independence, and a higher risk of falls, fractures, and metabolic diseases like Type 2 diabetes. In short, maintaining muscle is key to staying active and living life on your terms.

Muscle is more than just strength—it’s your body’s metabolic powerhouse. It helps regulate blood sugar, stores essential nutrients, and even plays a role in immune function. The bad news? Starting around age 50, we naturally lose about 1% of muscle mass and 3% of muscle strength each year. Periods of inactivity—like a hospital stay or just spending too much time sitting—can accelerate this process even further.

How to Keep Your Muscles Strong as You Age

The good news? Muscle is incredibly adaptable! Even in older age, you can build and maintain strength with the right approach. Here’s how:

1. Strength Training is a Game-Changer

Resistance training (a.k.a. lifting weights or using resistance bands) is one of the best ways to maintain muscle. You don’t have to lift heavy—light weights or bodyweight exercises can do the trick. Even sporadic strength training can help counteract muscle loss and keep you strong.

2. Eat More Protein

Muscles need protein to grow and stay strong. Research shows that older adults need more protein than the standard guidelines suggest. Aim for 1.2 – 1.6 grams per kilogram of body weight daily from a mix of animal and plant-based sources. Think lean meats, fish, eggs, dairy, beans, and legumes.

3. Stay Active Daily

Even small reductions in daily movement can lead to muscle loss. Try to keep your step count up, stay active throughout the day, and avoid long periods of sitting. Walking, yoga, swimming, and even gardening can make a big difference.

4. Don’t Wait—Start Now!

It’s never too late to build strength and invest in your future health. Think of exercise and good nutrition as your “retirement savings plan” for your body. The sooner you start, the better, but even small changes today can help you stay independent and thriving later in life.

The Bottom Line

A long life is great—but a strong, healthy, and active life is even better. By focusing on muscle health through exercise and nutrition, you can close the gap between healthspan and lifespan, maintain your independence, and enjoy the years ahead to the fullest. So, why wait? Start building a stronger, healthier future today!
