The Cost of Staying Small: Why Muscle Matters for Women in Midlife

Has anyone ever said something that made you so angry you’re still thinking about it almost a year later?

Last summer, I was helping a family member with an estate sale. My sister-in-law and I were selling a heavy workbench to a man. When he was ready to move it to his truck, he looked at the two of us and asked:

“Is there a man around who can help me move this?”

Now, I’m getting stronger. But my sister-in-law does CrossFit and regularly lifts heavy. She ignored his comment, picked up her end of the workbench, and waited for him to grab his side.

When he started to ask for a man again, I rolled my eyes and said, “She’s strong. You’re fine.”

And she carried her end without a problem — while I was secretly hoping he might need to take a break.

It wasn’t the bench that bothered me.

It was the assumption.

He was repeating what many of us have been conditioned to believe: women are fragile, strength is “masculine,” and women should need help.

Respectfully, I disagree.

Women Are Meant to Be Strong

Have you ever seen a little girl pick something up and proudly declare, “I’m so strong!”? Of course you have.

Have you ever seen a little girl sprint across the grass yelling, “Look how fast I am!”? Absolutely.

Have you ever seen a little girl look in the mirror and wish she were skinnier — unless she’s heard another woman say it first? I doubt it.

Strength is natural. Pride in our physical ability is natural. The desire to shrink ourselves is learned.

And yet, here we are again. The current trend encouraging women to be as small as possible is disheartening. I lived through the “heroin chic” era of the ’90s. I genuinely believed we had moved past glorifying extreme thinness.

Some women are naturally thin — and that’s perfectly fine.

But chronic underfueling and loss of muscle in midlife can increase the risk of bone loss, metabolic decline, and hormonal disruption. Shrinking at all costs comes with consequences.

Why do strong muscles matter for women?

If I had to choose one habit that would benefit women the most long-term?

Lifting weights. Hands down.

And I say that as someone who doesn’t always love doing it — but does it anyway.

1. Muscle Supports Metabolism

Muscle tissue burns more calories than fat at rest. It increases calorie burn during activity and can elevate metabolic rate through post-exercise recovery. In short: muscle supports a healthy metabolism.

2. Muscle Protects Bone Density

As we move through perimenopause and menopause, bone density naturally declines. Loss of muscle mass often accompanies that decline.

Strength training helps increase muscle mass and can improve bone density over time. That matters.

Have you ever worried about your mom or grandmother falling and breaking a hip? Falls are one of the biggest reasons older women lose their independence.

Building strength now is one of the best long-term investments you can make.

3. Muscle Supports Hormonal Health

Strength training improves insulin sensitivity and supports healthy estrogen metabolism — both critical in midlife. When we build muscle, we’re not just changing how our bodies look. We’re supporting how they function.

4. Muscle Improves Performance and Reduces Injury Risk (Especially for Runners)

If you’re a runner, strength training isn’t optional — it’s foundational.

Running is repetitive. Every step is a small impact. Multiply that by thousands of steps per run, week after week, month after month. If your muscles aren’t strong enough to absorb and control that force, something else will.

Your knees.

Or your hips.

Or your Achilles.

Or your IT band.

(I could keep this list going for a while.)

Stronger glutes help stabilize the pelvis and reduce stress on the knees.

Stronger hamstrings and calves support stride efficiency and protect connective tissue.

A stronger core improves posture and running economy, helping you maintain form as fatigue sets in.

In other words, muscle helps you handle the miles.

Strength training also improves force production, which can translate to better speed and power. That means you can become a stronger runner.

And perhaps most importantly: lifting helps you tolerate training load.

Injury prevention isn’t about luck. It’s about resilience. When your muscles are strong, your body is better equipped to adapt to stress instead of breaking down under it.

If you love running, lifting weights isn’t cross-training.

It’s longevity training — and that same principle applies whether you run or not.

Train for the Life You Want

Strength training isn’t just about aesthetics — even though, let’s be honest, muscle looks incredible on women. Muscles matter for women.

It’s about building the capacity your body needs to live the life you want.

I hope to have grandkids someday. I want to pick them up. Chase them around the yard. Go hiking. Play kickball. Do whatever they dream up.

As much as I loved my grandmother, I don’t want to spend my 80s sitting in a recliner watching game shows because I’m too frail to move comfortably.

I want to be out living my life.

Women come in all shapes and sizes. Our worth has never been tied to our pants size.

Let’s stop connecting value to thinness.

Let’s stop accepting the idea that we’re delicate.

Let’s stop shrinking to make someone else comfortable.

Let’s build muscle.

Let’s build resilience.

Let’s build independence.

Let’s get strong and fierce and cause a little chaos when we’re 80.

Who’s in?
