Strength Training for Women Over 50:
How to Protect Bones, Muscles, and Your Weight During Menopause

Menopause isn’t just about hot flashes and poor sleep. Something is happening inside your body that you can’t feel yet. Your bones are getting thinner. Your muscles are losing weight faster. And your fat is shifting.

The good news is that training is one of the most effective things you can do for all three parts. Here you will get facts, figures and a concrete way forward.

What is actually happening in the body?

Here is the section on figures and facts about menopause, set up so that the text and source references flow naturally:

In Denmark, the average age of the last menstrual period is around 51 to 52 years (source: sundhed.dk, University of Copenhagen). However, menopause begins several years earlier, often as early as the mid-40s. When estrogen drops, the body loses an important protector. Estrogen slows down the natural breakdown of bones. When it disappears, the breakdown occurs faster than the build-up.

The result is measurable. In the years around menopause, women lose an average of 1 to 2 percent of their bone density per year. In some cases, the loss is as high as 3 to 5 percent per year (source: Cleveland Clinic, Endocrine Society). Over the first five years or so, a woman can lose up to 20 percent of her bone density. One in three women in Denmark develops osteoporosis at some point in their lives. Up to one in four Danes over 50 already has it without knowing it (source: Osteoporosis Association).

It happens silently and without symptoms. Most people only notice it when they vomit something.

The muscles also atrophy.

At the same time, something happens to the muscles. From the age of 30, we lose about 3 to 5 percent of muscle mass every decade (source: Office on Women’s Health). During menopause, this happens more strongly because the hormonal changes affect the muscles in addition.

Less muscle mass means less strength, poorer balance and a higher risk of falling. And when you have fragile bones, a fall is the most dangerous thing that can happen.

Why the weight shifts

Many people find that their weight creeps up even though they eat as they usually do. It’s not a matter of lack of willpower. When estrogen drops, the body stores more fat around the stomach. This is called visceral fat and is deposited around the internal organs (source: Frontiers in Endocrinology, 2023).

But the explanation is not just a metabolism that stops. Your resting metabolism actually doesn’t drop nearly as much from estrogen alone as many people think. Research shows that metabolism is quite stable from age 20 to around 60 (source: Pontzer et al., Science, 2021). What really changes is how much you move during the day. Lower estrogen, poorer sleep, and getting older mean that you unconsciously move less. You walk a little less. You sit a little more. You make fewer of the small movements throughout the day that used to use energy. Research links weight gain during menopause to a decrease in daily physical activity of up to 40 percent (source: Review of Menopause and Physical Activity, 2023).

So the body does not stop you from burning. It is the daily movements that become fewer, and at the same time the fat moves to the stomach. The good news is that you can influence both. More muscle and more daily activity pulls in the right direction.

The good news: Training works

This is where things get positive. Research is very clear that the right training can reverse a large part of the development.

The strongest example is the Australian LIFTMOR study from 2018. Postmenopausal women with low bone density did heavy resistance training twice a week for 30 minutes over eight months. The exercises were deadlifts, squats and overhead presses combined with small jumps. The result was an improvement in bone density in the spine of about 4 percent and in the femoral neck of about 2 percent compared to the control group who did light training (source: Watson et al., Journal of Bone and Mineral Research, 2018).

It’s remarkable. While most people at that age lose bone mass, the participants actually built it up.

Strength training also helps with muscle and weight. The research shows that strength training is the best type of training for building and maintaining muscle mass, while cardio training is best for burning fat. The combination gives the best result (source: Frontiers in Endocrinology, 2023).

What is important for bone strength?

Bones are living tissues. They become stronger when they are stressed, just like muscles. Four things are crucial:

Load. Bones need to be exposed to a force that is large enough to start building. Light weights and long walks are healthy, but they are rarely enough on their own to build bone. Heavy lifting and high-resistance exercises provide the signal the bones need.

Impact and weight-bearing training. Bones respond particularly well to weight-bearing exercises and low impact. This is exercise where the skeleton bears the body’s weight and where there is light strain through the legs and spine. Walking, stair climbing, small hops and jumps send a strong signal to the bones to become denser. In the LIFTMOR study, small hops with landing were a regular part of the program (source: Watson et al., 2018). Swimming and cycling are healthy for the heart, but they do not build bone in the same way because the weight is carried by the water or the bike.

Progression. The load needs to increase over time. The body adapts, so what was hard last month needs to be a little harder the next. This is where a plan and a trainer make a difference.

Variety and balance. A good program is not just about heavy lifting. It also includes balance training and mobility. Balance prevents falls, and falls are the direct cause of most fractures.

Isn't it dangerous to lift heavy weights with fragile bones?

That’s the most important question, and the answer is nuanced. Heavy training is very effective, but it has to be done right.

In the LIFTMOR study, training was supervised throughout. Participants spent the first month learning the technique using only bodyweight and light weights before increasing the load. They trained in small groups with a physiotherapist present (source: Watson et al., 2018).

This is a point that needs to be taken seriously. When the same workout is copied at home without training and supervision, there have been cases of injuries, including back pain and fractures (source: MelioGuide, physiotherapist Margaret Martin). Heavy lifts like the deadlift require good technique to be safe.

The bottom line is not to avoid heavy training. The bottom line is to start from the right place. Learn the technique first. Build up gradually. Get guidance, especially if you are a beginner or have already been diagnosed with osteoporosis. Talk to your doctor before you start if you have a diagnosis.

The diet must follow

Exercise alone is not enough. Bones and muscles need building blocks. The most important ones are protein, calcium and vitamin D.

The European expert group ESCEO recommends for postmenopausal women (source: Rizzoli et al., ESCEO consensus):

Protein: 1.0 to 1.2 grams per kilogram of body weight per day. For a 65-kilogram woman, that’s about 65 to 78 grams of protein daily. Ideally, 20 to 25 grams of good-quality protein at each main meal.
Calcium: Approximately 1000 mg per day.
D-vitamin: 800 internationale enheder, svarende til 20 mikrogram, om dagen.

De danske anbefalinger ligger på linje med dette. Dansk Endokrinologisk Selskab anbefaler mindst 800 mg calcium dagligt til voksne, og mindst 1000 til 1200 mg for personer med eller i risiko for knogleskørhed. Sundhedsstyrelsen anbefaler 20 mikrogram D-vitamin dagligt året rundt til personer i øget risiko for knogleskørhed (kilde: Sundhedsstyrelsen, Dansk Endokrinologisk Selskab). En gennemgang af forsøg viser, at tilstrækkeligt calcium og D-vitamin reducerer risikoen for knoglebrud med cirka 15 procent og for hoftebrud med cirka 30 procent (kilde: Sundhedsstyrelsen).

Protein close to training helps muscles build. Calcium and vitamin D are what bones are made of, and vitamin D is hard to get enough of in the Danish winters.

How to get started

Here is the concrete way forward, set up as a nice, clear list and cleaned of the strange line breaks:

You don’t have to throw yourself into the heaviest lifting from day one. A sensible start looks like this:

Strength train twice a week. That’s enough to get results.
Start with the big exercises that use a lot of muscles. Squats, a form of deadlift, and presses are the core.
Learn the technique properly before increasing the weight. The first few weeks are all about moving correctly.
Increase the load slowly and in a planned manner, little by little.
Supplement with balance exercises and a little fitness.
Make sure you get enough protein, calcium and vitamin D.

Remember one important thing about pace: Your muscles get stronger faster than your tendons, joints, and bones. Tendons and joints take longer to adapt, and bones build even more slowly. This means you may feel ready for more before your connective tissue and bones do. That’s why you need to increase the weight at a pace that works your entire body, not just your muscles. Going too fast is one of the most common causes of injury.

The most important thing to remember

Menopause triggers a loss of bone and muscle that you can’t feel, but is measurable. You can’t stop the drop in estrogen, but you can greatly influence what happens to your body afterward. Heavy and well-planned strength training is one of the best investments you can make in your own health after 45. It protects your bones, maintains muscle, and helps with weight.

The most important thing is to do it right from the start. With good technique, a plan, and gradual increase, heavy training is not a risk. It is one of the most proven ways to stay strong and independent for the rest of your life.
