If I could write one prescription for every woman who walks into my office in her 40s or 50s, it wouldn't be a supplement or a lab test. It would be strength training.

November is Osteoporosis Month, and when I wrote about bone health before menopause last month, I promised I'd come back to this. Because strength training doesn't just help your bones. It touches almost everything women come to me worried about in midlife: weight, energy, blood sugar, heart health and how strong they feel in their own bodies.

1. It helps with body fat, including the belly fat

This is the one I hear about most. "I haven't changed anything, but my body has." Many women notice weight shifting to their midsection as estrogen declines.

Here's the encouraging part. Both strength training and aerobic exercise, on their own or together, help with weight management. When it comes to lowering body fat percentage, how long and how hard you train both matter.

And this is the part I really want you to hear: research shows that women in perimenopause and after menopause are just as capable of losing weight and abdominal fat as younger women when they follow a higher-intensity exercise program. Your body hasn't stopped responding. It may just need a different approach than the one that worked at 30.

2. It protects your heart and metabolism

Regular moderate-intensity exercise is linked with healthier body composition and a lower risk of cardiovascular disease and diabetes.

That matters because midlife is when a lot of women see their blood pressure, cholesterol and blood sugar start to creep up for the first time. Muscle is one of the biggest users of glucose in your body, so building it is one of the most practical things you can do for your metabolism.

3. It's one of the best things you can do for your bones

As estrogen declines, bone loss speeds up. Exercise, including strength training, helps prevent that loss.

Muscle and bone work together. When muscle pulls on bone, it sends a signal to keep that bone strong. That's why I'd rather see a woman lifting something challenging twice a week than walking the same easy loop every day. Walking is great. It's just not enough on its own.

4. It keeps the muscle you have (and helps you build more)

We naturally lose muscle as we age, and the hormonal changes of perimenopause and menopause speed that up. Diet and exercise are the two biggest levers we have to hold onto it.

This is personal for me. After my neck injury this summer, I lost strength in my left arm, and rebuilding it has been slow, humbling work. It's also been a reminder of how quickly strength goes when we stop asking our bodies for it, and how much it's worth fighting for.

What kind of training I recommend

You don't need to become a powerlifter. What I recommend for most women is functional strength training that includes balance, especially if bone health is on your radar.

  • Strength work. Weights, bands or your own body weight, with the goal of gradually getting a little stronger over time.

  • Balance work. Single-leg exercises, step-ups and moves that challenge your stability. Balance is what helps prevent the falls that lead to fractures.

  • Some impact, if it's right for you. Strength training that adds a bit of impact along with balance is especially helpful for bones. If you have osteoporosis or joint concerns, we start lower and build up.

  • Mobility and stretching. To keep you moving well and training consistently.

Aim for at least two strength sessions a week. If you're new, working with a qualified trainer is worth it. They'll help you start safely, use good form and keep progressing.

Why perimenopause is the best time to start

If you're in perimenopause, this is your window. The effects of declining estrogen on your bones, muscle and metabolism are just beginning, which makes this the ideal time to get ahead of them, rather than trying to rebuild later.

That said, it's never too late. I've seen women start in their 60s and get stronger. You just have to start.

The bottom line

Strength training is the closest thing I have to a prescription that helps everything at once. It supports a healthier body composition, protects your heart and metabolism, helps your bones, and keeps you strong enough to live the life you want for decades.

Start where you are. Lift something a little challenging. Do it twice a week. And keep going.

Your next step

If you're in perimenopause and wondering how much your symptoms are affecting your life, take the Perimenopause Impact Score. It's a short quiz that helps you see where you're at.

If you live in Alberta or BC and want to talk through your next step, you can book a free Hormone Clarity Call. It's 10 to 15 minutes to go over your symptoms and figure out what makes sense for you.

I see patients in person in Calgary at BioRevive Regenerative Medicine and the Mount Royal University Injury & Prevention Clinic, as well as in Fernie, BC. I also offer virtual hormone care for women anywhere in Alberta and BC.
