Why Strength Training Is Essential — At Any Age

The other day, I was walking down the street and noticed a woman in distress. She was kneeling on one leg, trying hard to get up. I rushed over, thinking she might have broken her leg. Thankfully, she hadn’t—but she couldn’t stand up on her own, lthough she is a young woman who looks around 30 years old.

She was slightly overweight, and I couldn’t lift her just by the arm. So, I stepped behind her, and helped her up to stand up.

That moment stuck with me.

I often tell my mom—and everyone around me—keep moving, keep training, because if you fall, strength might be the reason you can get back up safely.

What Is Strength Training?

Strength training, also called resistance training, is the ability to produce force against resistance—whether that’s weights, resistance bands, or even your own body weight [1].

It’s not random exercise. True strength training is:

• Structured

• Progressive

• Goal-oriented

It involves selected exercises performed over time to safely build strength. Recovery is also essential—your muscles grow when you rest, not just when you lift.

Strength Training and Aging: A Scientific Perspective

Starting around age 40, most people begin to lose about 1% of their muscle mass every year, a condition called sarcopenia [2]. It’s a natural part of aging—but it accelerates with inactivity, illness, and poor nutrition.

This loss of muscle affects:

• Your ability to stand up, climb stairs, or carry groceries

• Your balance and stability

• Your risk of falls, fractures, and even hospitalizations

In fact, decreased strength has been directly linked to higher risk of disability, dependence, and early mortality in older adults [2].

But here’s the good news:
Strength training can reverse or prevent this process.

According to research, resistance training:

• Improves muscle mass and function even in people over 70

• Reduces the risk of osteoporosis and bone fractures [2]

• Supports independence by maintaining physical function

Proven Benefits of Strength Training

Backed by science, here’s what strength training can do for your body and mind:

1. Build Lean Muscle & Burn Fat

Resistance training increases lean body mass and helps decrease visceral fat—the dangerous fat stored around organs, which is linked to inflammation, diabetes, and heart disease [1].

2. Boost Cardiovascular Health

Contrary to old beliefs, lifting weights is good for your heart. Studies show strength training improves blood pressure, blood sugar, and even triggers beneficial changes in the heart muscle itself [1].

3. Improve Mental Health

Strength training may help reduce symptoms of depression, anxiety, and improve sleep quality [1]. While results vary by study, many participants report improved mood and confidence.

4. Protect Against Falls & Injury

When you train your muscles regularly, your balance improves, your reflexes sharpen, and your body learns to react better.
So, if you fall—you’re more likely to catch yourself or get up safely. Just like the woman I helped, but with the strength to do it on her own.

Why Doing It Alone Can Be Risky

Strength training is incredibly beneficial—but doing it incorrectly can lead to injury, especially for beginners.
Some risks include:

• Using poor form or lifting too much weight

• Skipping rest and recovery

• Overtraining without a clear plan

That’s why working with a personal trainer—even online—can make a big difference. At Harmony Fitness, I help clients build strength safely, progressively, and with real support.
