Facem încălzirea înainte de antrenament.

Facem is the 1st person plural present tense of a face, which usually means to do or to make.

So facem = we do / we are doing.

In this sentence, it means:

• we do the warm-up
• or more naturally in English, we warm up

Romanian often uses a face with nouns where English might prefer a different verb.

Romanian usually does not need a subject pronoun when the verb already shows who is doing the action.

• facem already tells you the subject is we
• so noi facem = we do, but noi is optional

You would add noi only for emphasis, contrast, or clarity:

• Noi facem încălzirea înainte de antrenament.
  = We do the warm-up before training.

Without noi, the sentence is perfectly normal.

Încălzirea means the warm-up.

It comes from the noun încălzire, which means warming up or warm-up.

Breakdown:

• încălzire = warm-up / warming up
• încălzirea = the warm-up

So the ending -a here is not part of the basic noun only—it is the definite article attached to the end of the noun.

That is very normal in Romanian.

In Romanian, the definite article is usually attached to the end of the noun, not written as a separate word like English the.

Examples:

• băiat = boy

• băiatul = the boy

• fată = girl

• fata = the girl

• încălzire = warm-up
• încălzirea = the warm-up

So Romanian says încălzirea, where English says the warm-up.

Yes, you can.

• Facem încălzire = We warm up / We do warm-up
• Facem încălzirea = We do the warm-up

The version with the definite article can sound like:

• a specific warm-up
• the usual warm-up
• the warm-up phase as a known part of training

The version without the article can sound a bit more general.

Both are possible, but încălzirea fits well if you mean a specific warm-up routine before training.

Because Romanian normally uses the fixed expression înainte de to mean before when it is followed by a noun or infinitive-like phrase.

So:

• înainte de antrenament = before training / before the workout
• înainte de masă = before the meal
• înainte de a pleca = before leaving / before going away

So you should usually learn înainte de as a unit.

Antrenament can mean:

• training
• practice
• workout

The best translation depends on context.

In this sentence, natural English possibilities are:

• before training
• before practice
• before the workout

If this is about sports, gym, or exercise, all of these can make sense depending on the situation.

In înainte de antrenament, the noun is used in a more general way: before training / before the workout session.

Romanian often uses înainte de + noun without the definite article in this kind of expression.

If you wanted a more explicitly definite structure, Romanian can also use forms like:

• înaintea antrenamentului

That is more formal or more explicitly before the training session.

So:

• înainte de antrenament = very common, natural
• înaintea antrenamentului = also correct, more formal/bookish in many contexts

Romanian present tense usually covers both ideas.

So facem can mean:

• we do
• we are doing

The exact meaning depends on context.

In this sentence, it is most naturally understood as a habitual or general statement:

• We do the warm-up before training

But in the right context it could also mean:

• We’re doing the warm-up before training

Romanian does not usually make the same strict distinction English does between do and are doing.

Because pe is not used with every direct object.

In Romanian, pe is commonly used with:

• people
• animate beings
• personal names
• certain pronouns

For example:

• Văd fata. = I see the girl.
• O văd pe fata aceea. = I see that girl.

But încălzirea is an inanimate thing/concept, so pe is not needed.

So:

• Facem încălzirea is correct
• Facem pe încălzirea is wrong

Yes. Romanian word order is fairly flexible.

The original sentence:

• Facem încălzirea înainte de antrenament.

You could also say:

• Înainte de antrenament, facem încălzirea.

Both mean the same thing. The second version puts more emphasis on before training.

The original order is very natural and neutral.

A rough pronunciation guide is:

în-cuhl-zi-ree-a

A few important sounds:

• î = a central vowel, somewhat like a tight, neutral sound not found exactly in English
• ă = a short uh sound, like the a in sofa
• zirea = roughly zee-ree-a

So the whole word flows something like:

een-cuhl-ZEE-ree-a
with the stress typically on zi.

The exact Romanian pronunciation is subtler than English spelling can show, but that approximation helps.

Yes, it is a natural sentence.

A few natural Romanian ways to express this idea are:

• Facem încălzirea înainte de antrenament.
• Facem încălzire înainte de antrenament.
• Ne încălzim înainte de antrenament.

These are slightly different in feel:

• Facem încălzirea = we do the warm-up
• Facem încălzire = we do warm-up / we warm up
• Ne încălzim = we warm ourselves up / we warm up

All are correct, but your sentence is completely normal and idiomatic.
