वार्म-अप ज़रूरी है।

• वार्म-अप = warm-up
• ज़रूरी = necessary / important
• है = is

So the sentence structure is literally:

Warm-up necessary is.

This is normal Hindi word order. In natural English, it becomes Warm-up is necessary.

It is a very common English loanword used in Hindi, especially in contexts like exercise, sports, dance, yoga, school, and fitness.

Hindi often uses English words directly, especially for modern, technical, or casual everyday vocabulary. So a speaker may say:

• वार्म-अप ज़रूरी है।
• वर्कआउट शुरू करने से पहले वार्म-अप करो।

Even though the word comes from English, it is written in Devanagari here.

It is pronounced approximately like warm-up in English, adapted slightly to Hindi sound patterns.

A rough guide:

• वार्म ≈ vaarm / warm
• अप ≈ up

A full rough transliteration is:

vaarm-ap

In real speech, the pronunciation may vary a bit depending on the speaker’s accent and how closely they are copying the English sound.

The hyphen helps show that this is a compound borrowed expression: warm-up.

In informal Hindi writing, you may see variation:

• वार्म-अप
• वार्म अप

Both are understandable. The hyphen just makes the compound clearer.

ज़रूरी means necessary, required, or sometimes important, depending on context.

In this sentence, necessary is the clearest translation:

• वार्म-अप ज़रूरी है। = Warm-up is necessary.

It can also be used in many other sentences:

• पानी ज़रूरी है। = Water is necessary.
• आराम ज़रूरी है। = Rest is necessary.

ज़रूरी is pronounced roughly za-roo-ree or za-rū-rī.

The first letter ज़ is ज with a dot underneath, called a nukta.
That dot changes the sound slightly, so ज़ is pronounced more like z, while plain ज is more like j.

So:

• ज़रूरी ≈ zaroori
• not jaroori

That said, in everyday speech and writing, many people do not strongly distinguish ज़ and ज, and you may sometimes see जरूरी written instead of ज़रूरी. Both are common, but ज़रूरी is the more precise spelling.

है is the present-tense form of to be for he/she/it/this/that and singular nouns.

Here it means is:

• ज़रूरी है = is necessary

Hindi often puts this kind of verb at the end of the sentence, so:

• वार्म-अप ज़रूरी है। literally = Warm-up necessary is.

This is completely normal Hindi word order.

Because वार्म-अप is being treated as a singular thing.

• है = is (singular)
• हैं = are (plural or respectful)

So:

• वार्म-अप ज़रूरी है। = Warm-up is necessary.
• ये एक्सरसाइज़ें ज़रूरी हैं। = These exercises are necessary.

Even if the English source word is borrowed, Hindi still decides whether it is singular or plural for grammar purposes.

Hindi usually does not use articles like a, an, and the the way English does.

So Hindi can say simply:

• वार्म-अप ज़रूरी है।

Depending on context, this could be understood in English as:

• Warm-up is necessary
• A warm-up is necessary
• The warm-up is necessary

The exact English article depends on the situation, but Hindi does not need to state it here.

Because ज़रूरी is one of many adjectives in Hindi that usually do not change for gender or number.

Compare this with an adjective that does change:

• अच्छा लड़का
• अच्छी लड़की

But ज़रूरी stays the same:

• आराम ज़रूरी है।
• नींद ज़रूरी है।
• किताबें ज़रूरी हैं।

What changes is usually the verb:

• singular: है
• plural: हैं

So in this sentence, ज़रूरी stays the same no matter what noun it describes.

Yes, absolutely.

• वार्म-अप ज़रूरी है। = Warm-up is necessary.
• वार्म-अप करना ज़रूरी है। = It is necessary to warm up / Doing a warm-up is necessary.

The version with करना makes the action more explicit.
The shorter version is very natural too, especially in speech, signs, instructions, or general advice.

It is natural and common, but it leans a bit modern and conversational because of the English loanword वार्म-अप.

In everyday Hindi, especially in gyms, sports, school, and health discussions, this sounds completely normal.

A more Sanskrit-based or more formal alternative might avoid the English word, but in real life many speakers would prefer वार्म-अप because it sounds direct and familiar.

Yes. Depending on context, ज़रूरी can sometimes sound like:

• necessary
• important
• essential

So वार्म-अप ज़रूरी है। could be understood as:

• Warm-up is necessary
• Warming up is important
• A warm-up is essential

If the exact meaning has already been given to the learner, you should follow that meaning, but it is useful to know that ज़रूरी has a small range of natural English translations.
