about your bones - and what you
you can do about it yourself.

Summary: Already around the age of 30 you begin gradually to lose bone mass, without being able to see or feel it yourself. The good news is that you can do something about it yourself. Read on!


1. Your bone mass peaks at ages 25-30

Did you also believe that bone loss was only relevant for the elderly?

It starts earlier than you think

Bone mass typically peaks around ages 25–30. After that most people gradually lose more than they build up. Regular strength training helps maintain the bone mass you have.

👉 Prevent bone loss

2. Your bones get stronger from loading

Did you know that your bones respond to strength training – just like your muscles?

Loading = denser bone structure

Bones are living tissue. When your muscles pull on your bones, they get a signal to build up. It is the loading from strength training that keeps them strong.

3. Strong bones keep you on your feet

Did you know that many bone fractures later in life happen from a fall?

Strength training gives strong bones

Strength training provides stronger bones, better balance and more control over your body. You become more resilient and protect your bones from the falls that often lead to fractures.

👉 Build strong bones

4. You become strong for everyday life

When was the last time you thought about how much you lift and carry?

Get strong for everyday life

Strength training is not just about big muscles. It's about being able to carry, lift, and stand upright so your body can be used for many more years. 

👉 Get strong for everyday life

5. It is never too late to start

Are you over 40, 50 or 60 and thinking it's too late?

Start calmly today

Both muscles and bones respond to loading throughout life. Strength training also makes a difference later in life – the most important thing is to start gently and build up.

👉 Do heavy strength training at home

6. It takes less than you think

Do you think it requires hours at the gym every week?

It doesn't require a gym

The Health Authority recommends strength training at least 2 times a week. The hard part is rarely starting – it's maintaining it. And here the place where you train matters more than most think.

👉 See how easily it can be done

7. At home the biggest excuse disappears

How many times have you skipped training because you couldn't be bothered to go?

Remove the excuses for yourself

Transport, parking and changing can easily take an hour before you even get started. At home the barrier is low: You walk into the living room, and then you train.

👉 See how little space it can take

8. You train when it suits you

Does your training routine actually fit into your everyday life?

Train when it suits you

Early in the morning, while dinner is in the oven, or when the children are in bed. When exercise fits into everyday life, it becomes a habit – and that is a habit your bones benefit from.

👉 Find the right solution

9. Train at your own pace – without an audience

Have you ever felt watched at a gym?

Train for yourself

Many feel insecure when they have to learn new exercises in front of others. At home you can start completely from scratch, take the time you need, and build at your own pace.

10. Your bones can't see where you train

Do you really need a gym to do strength training correctly?

Strength training is about resistance

Your bones do not distinguish between weights in a gym and resistance in the living room. Dwhat counts is the load. All you need is something that gives your muscles resistance. See your options below.

You don't need a gym – just something that gives your muscles and bones resistance. Here are three ways to do it:
