How to Build a Strong Body in Midlife: A Guide to Strength for Women Over 40

If there is one empowering truth I’ve embraced as I move through midlife, it’s that movement really is medicine.

Yes, staying active can help us feel more comfortable in our clothes. But the real benefits go much deeper. So many of the women I work with start because they want to change how they look, but they quickly fall in love with how they feel: more energy, better sleep, a brighter mood, less aches and pains, more confidence in what their bodies can do.

It’s about that incredible feeling that comes from knowing you are truly strong.

Movement Goals for Midlife Women

Current guidelines recommend at least 150 minutes of moderate-to-vigorous aerobic activity per week, along with muscle-strengthening activities at least twice a week.

But here's the thing: many women aren't even close to that—not because they don't care about their health, but because life is full.

Between work, family, long commutes and endless to-do lists, there is often very little energy left for ourselves. And if you're also managing things like low bone density, arthritis or an old injury that makes you hesitate, it’s completely natural to feel uncertain about where to even begin.

When we're less active for long periods, we can gradually lose strength, fitness, balance and mobility. Everyday things can start to feel harder than they used to.

But I want you to hear this:It is never too late to start rebuilding.

What Kind of Exercise Is Best in Midlife?

I’m often asked what the “best” exercise is for women in our stage of life.

My answer is always the same: the best exercise is the one you enjoy, feel safe doing and can stick with.

Whether it’s walking with a friend, tending to your garden, dancing in the kitchen, practicing yoga or working out with my Midlife Warriors, it all counts.

These activities support cardiovascular health, mobility, mood and overall wellbeing.

However, if I could encourage you to prioritize one specific thing, it would be strength training.

Progressive strength training challenges our muscles and gives our bones a reason to adapt. It can help us maintain and build muscle, support bone health, improve strength and balance, and make everyday activities easier.

These aren't just gym goals. They are the foundation for staying capable and independent as we age.

I recently completed my BoneFit Advanced training with Osteoporosis Canada, and it deepened my passion for this work even more. It reinforced something I strongly believe: having low bone density shouldn't automatically make us afraid to move.

We just need the right guidance and a thoughtful plan.

What Does Strength Training Actually Look Like?

Please know that you don’t need to become a competitive bodybuilder, and you certainly don’t need to feel intimidated by a gym environment.

A progressive, well-rounded strength program is built around the same movements we use every day: Pushing. Pulling. Squatting. Hinging. Carrying.

I think of these as “life skills.”

They are the movements that allow you to lift groceries with ease, get up off the floor after playing with your kids or grandkids, reach into high cupboards and carry your fur babies with confidence.

This is what functional strength is all about. It’s about making life feel a little bit easier.

Is Strength Training Safe If You Have Osteoporosis?

This is where individualized guidance becomes especially important.

For many women with osteoporosis or low bone density, appropriately designed resistance and strength training can help maintain muscle, support bone health, improve strength and balance, and contribute to reducing fall risk.

But not every exercise is right for every woman.

Your starting point should take into consideration your bone health, medical history, current fitness level, injuries and confidence with movement.

The good news is that there is almost always a way to modify an exercise to meet you where you are.

You don't have to sit on the sidelines because you're unsure. We can find a path that feels right for you.

How Do You Start Strength Training?

If you've never lifted weights before, my advice is simple: Start where you are.

If you need medical clearance, get it. Then start slowly, learn the basics and build from there.

You might begin with bodyweight exercises, resistance bands, light dumbbells or even household objects.

As the exercises become easier, gradually increase the challenge: more resistance, slower tempo, a greater range of motion or a more challenging variation.

You don't need to be “fit” to start, and you definitely don't need to compare your journey to anyone else's.

Strength is built gradually, by showing up consistently and progressing at a pace your body can handle.

What I Focus on With My Midlife Warriors

That's exactly what I focus on with my Midlife Warriors.

Whether you're brand new to exercise, don't enjoy the gym or are returning to movement after years away, you'll find a supportive environment where you can work at your own level.

The community is completely virtual, and every new member starts with a 30-minute welcome call with me. We talk about your goals, experience, injuries or concerns, and any modifications you may need.

From there, we focus on progressive strength, balance, mobility and movements that translate into everyday life.

And perhaps my favourite part is the community.

Women in their 30s, 40s, 50s, 60s and 70s showing up for themselves and cheering each other on.

You don't need to know what you're doing before you start. That's what I'm here for.

Movement Is a Form of Self-Care

Movement isn't punishment for what we eat.

It's not something we have to earn, and it's not about trying to look 25 again. It's about building a body that can carry you through the next 25 years and beyond.

Strong.
Capable.
Independent.

If you've been thinking about starting but don't know where to begin, don't enjoy the gym, or feel nervous about exercising because of your bone health or other concerns, perhaps what you need isn't more motivation.

Maybe you need the right structure, guidance and community.

That's exactly why I created Midlife Warriors—to help women build strength safely, progressively and confidently, from the comfort of home.
