Bơi giúp cơ thể khỏe hơn.

Here Bơi literally means to swim, but in this sentence it functions like swimming in English.

So:

• Bơi = to swim / swimming
• Bơi giúp cơ thể khỏe hơn = Swimming helps the body become healthier

Vietnamese often uses a bare verb at the start of a sentence to talk about an activity in general, without needing a separate word like the act of or the -ing form.

Vietnamese does not need a dummy subject like English it.

In English, you might say:

• Swimming helps the body stay healthy.

In Vietnamese, you can simply start with the activity itself:

• Bơi giúp cơ thể khỏe hơn.

So Bơi itself is the subject here, understood as swimming in a general sense.

Giúp means help.

The basic pattern is:

• A giúp B + adjective/verb
• A helps B become/do ...

So here:

• Bơi = swimming
• giúp = helps
• cơ thể = the body
• khỏe hơn = healthier

Together: Swimming helps the body become healthier.

Vietnamese often leaves out words like become when the meaning is clear.

In English, we often say:

• helps the body become healthier

In Vietnamese, it is very natural to say:

• giúp cơ thể khỏe hơn

This literally looks like helps the body healthier, but the intended meaning is helps the body become healthier or helps the body be healthier.

Vietnamese often allows this kind of compact structure.

Cơ thể means the body and is a very common, neutral word.

Some related words:

• cơ thể = body (common, neutral, modern)
• thân thể = body (also correct, a bit more formal or literary in some contexts)
• người = body/person, depending on context

In this sentence, cơ thể is a very natural choice for talking about physical health.

Khỏe means healthy, well, or sometimes strong, depending on context.

Hơn means more and is used to form comparisons.

So:

• khỏe = healthy / strong
• khỏe hơn = healthier / stronger

In this sentence, khỏe hơn means healthier.

Good question. In Vietnamese, hơn can mark a comparison even when the second part is not explicitly stated.

So khỏe hơn means:

• healthier
• understood as healthier than before or healthier than without swimming

The comparison target is implied rather than spoken.

If you wanted to state it fully, you might say something like:

• Bơi giúp cơ thể khỏe hơn trước.
• Swimming helps the body become healthier than before.

But the shorter version is completely natural.

Yes. Khỏe can cover both healthy and strong/well depending on context.

So possible English renderings include:

• Swimming helps the body become healthier.
• Swimming helps the body stay healthy.
• Swimming helps strengthen the body.

The exact best translation depends on context, but the core idea is that swimming improves physical condition.

Vietnamese does not use articles the same way English does.

So:

• cơ thể can mean the body or a body, depending on context.

In a general health statement like this, English naturally uses the body, but Vietnamese simply says cơ thể without an article.

This is normal and not something missing.

Yes, it is a complete and natural sentence.

It sounds like a short general statement you might see in:

• a textbook
• a health article
• an exercise poster
• a lesson for learners

A longer version could be:

• Bơi lội giúp cơ thể khỏe hơn.
• Swimming helps the body become healthier.

Adding lội makes bơi lội, which also means swimming, often with a slightly more complete or activity-like feel. But bơi alone is perfectly fine.

Both can mean to swim or swimming.

• bơi = swim / swimming
• bơi lội = swimming, often slightly fuller or more activity-focused

In many contexts, they are interchangeable.

For example:

• Tôi thích bơi. = I like swimming.
• Bơi lội rất tốt cho sức khỏe. = Swimming is very good for health.

In your sentence, Bơi giúp cơ thể khỏe hơn is natural and concise.

A rough pronunciation guide is:

• Bơi ≈ buhy / boi with a Vietnamese vowel not exactly found in English
• giúp ≈ zoop in northern Vietnamese, often closer to yoop in southern Vietnamese
• cơ thể ≈ guh thae (very rough)
• khỏe hơn ≈ khwair huhn (very rough)

A few useful notes:

• gi in northern speech often sounds like z
• kh is a breathy sound, a bit like German ch or a strong h/k combination
• tones matter a lot, so rough English spelling can only help a little

If you are learning pronunciation, it is best to listen to native audio for this sentence.

Yes, you can express the same idea in other natural ways.

For example:

• Bơi giúp cơ thể khỏe hơn. = Swimming helps the body become healthier.

• Cơ thể khỏe hơn nhờ bơi. = The body is healthier thanks to swimming.

These are both natural, but the focus is slightly different:

• Bơi giúp... emphasizes swimming as the helpful activity
• ...nhờ bơi emphasizes the result and says it happens thanks to swimming

So the original sentence is not the only possible way, but it is perfectly correct and natural.
