If you look online, you’ll find a ton of people who claim that sit-ups can stunt your growth.

Interestingly, there are others who say that sit-ups don’t stunt your growth but can actually make you taller.

While the reasoning behind these claims vary, it seems to be a fairly common question – do sit-ups stunt your growth?

In this article, we discuss points surrounding this question.

Do Sit-Ups Stunt Growth?

There’s no evidence to suggest that sit-ups can stunt your growth.

There was a widely believed theory that is young children done resistance exercises (like sit-ups), their growth would be stunted.

However, many respected scientists have disproven this theory.

Exercise will only stunt your growth if you injure your growth plates during early development phases of your life.

While this can happen during exercise, it can also happen during any type of physical activity.

Do Sit-Ups Improve Your Posture?

Yes, sit-ups can significantly improve your posture.

Poor posture can have a negative effect on your overall health, fitness, and wellbeing. Whereas improving your posture can increase your vitality, reduce your injury risk, and make you stronger.

Sit-ups are a great exercise for improving your posture and they can help your body’s stability, balance, and overall strength.

Do Sit-Ups Increase Height?

Sit-ups don’t increase your height.

They can however make you appear taller by improving your posture.

As your posture improves, your shoulders will be back, your chest will be held higher, and you’ll have a seemingly taller frame.

This is likely why some people believe sit-ups can make you taller.

In reality though, they make you look taller as your posture improves over time.

What Factors Affect Your Height?

Childhood Nutrition

Without adequate nutrition, children can have their height severely restricted.

While a balanced diet is important for everyone, it’s especially vital for growing kids.

Fruit and vegetables help ensure they get sufficient vitamins and minerals while protein and calcium help bone development.

As you get older, your nutrition habits won’t impact your height, but it can still have a massive impact on your overall wellbeing.

Nutrition is important but especially for young children.


Genetics is the #1 factor that determines your height.

If your parents are tall, you’ll likely be tall too.

If many of your family members are short, then you’ll probably be short yourself.

Genetics plays a huge role in many aspects of our life such as health, height, appearance, and even certain behaviours.

Without medical intervention, it’s difficult to do anything that goes against your genetic makeup.

Medical Conditions

Your height can be affected by some medical conditions.

In these cases, there isn’t much you can do to change your height, but you’ll likely have medication or certain exercises you’ll need to do to help manage your health.


While your posture doesn’t affect your height, it can make a huge difference to how tall you appear.

Bad posture can leave you with a hunch back and make you look shorter.

Good posture can give you an appearance of someone who is taller than others with worse posture.

You should always aim to improve your posture as it has many benefits as well as making you look taller.

Are There Any Proven Ways To Get Taller?

There aren’t any proven ways to get taller once you’ve stopped growing naturally.

Some folks who aren’t satisfied with their height might go through painful and expensive surgery to change their height by a few inches, but this isn’t something many people do.

Unless there’s an underlying medical issue, most people’s height is determined by their genetics, their childhood nutrition and behaviours, and their posture.


In summary, sit-ups won’t make you taller or stunt your growth. Your height is largely determined by your genetics and exercises like sit-ups will play a negligible role.

That’s all for this article, but how many sit-ups should a 13 year old do? Or what’s the average amount of sit-ups for a 14 year old?

Hope this helped!
