Hacemos el calentamiento articular antes de la práctica libre.

Hacemos is the 1st person plural present-tense form of hacer, so it means we do / we make.

The verb hacer in the present tense:

• hago = I do
• haces = you do
• hace = he/she/it does
• hacemos = we do
• hacéis = you all do (Spain)
• hacen = they do

So Hacemos... means We do... or We are doing..., depending on context.

In Spanish, subject pronouns are often left out because the verb ending already shows who the subject is.

• Hacemos already tells you the subject is we
• So Nosotros hacemos... is possible, but usually unnecessary

You might include nosotros only for emphasis or contrast:

• Nosotros hacemos el calentamiento articular, pero ellos no.

Here, hacer means to do or to perform.

In English, you might say:

• We do the warm-up
• We perform the warm-up

Spanish often uses hacer in situations where English uses do, perform, or even something more specific:

• hacer ejercicio = to exercise
• hacer una pausa = to take a break
• hacer un calentamiento = to do a warm-up

So this is a very natural use of hacer.

Calentamiento means warm-up, and articular means joint-related or for the joints.

So calentamiento articular is something like:

• joint warm-up
• joint mobility warm-up
• articular warm-up

In Spanish, adjectives often come after the noun, unlike in English:

• calentamiento articular
• literally: warm-up joint-related

That word order is normal in Spanish.

Here, articular is an adjective, not a verb.

It comes from articulación = joint or articulation.
So articular means related to the joints.

Even though articular can also be a verb in other contexts meaning to articulate, in this sentence it is clearly an adjective because it describes calentamiento.

Spanish nouns have grammatical gender, so the article must match the noun:

• el calentamiento because calentamiento is masculine
• la práctica because práctica is feminine

A few useful patterns:

• Nouns ending in -miento are usually masculine:
  el calentamiento, el movimiento
• Many nouns ending in -a are feminine:
  la práctica, la pausa

You usually need to learn the gender together with the noun.

Because antes needs de when it is followed by a noun or another phrase.

So:

• antes de la práctica libre = before free practice
• antes de comer = before eating

But antes can appear alone if the rest is understood:

• Lo hacemos antes. = We do it before / earlier.

So in this sentence, de is required because it introduces what comes after: la práctica libre.

Because the expression is antes de + noun/infinitive.

After antes, Spanish uses de, not a:

• antes de la práctica libre
• antes de entrenar

Using a here would be incorrect.

Práctica libre means free practice.

In many sports, physical education, dance, martial arts, or training contexts, it usually refers to a period when participants practise more freely, independently, or with fewer instructions.

So:

• la práctica libre = free practice / open practice session

Again, the adjective usually comes after the noun in Spanish:

• práctica libre
• literally: practice free

Yes. The Spanish present tense can cover several ideas that English often separates:

• We do
• We are doing
• We usually do
• We do as a routine

So Hacemos el calentamiento articular antes de la práctica libre could mean:

• a general routine
• a habitual action
• what happens in a class/session
• even something currently happening, depending on context

Spanish uses the simple present more broadly than English does.

Yes, realizamos is grammatically correct and means something like we carry out / we perform.

But the tone is a bit different:

• hacemos sounds more natural and everyday
• realizamos sounds more formal, technical, or institutional

In normal speech, especially in sports or class settings, hacemos is usually the more natural choice.

This is a very standard Spanish sentence order:

• Hacemos = verb
• el calentamiento articular = direct object
• antes de la práctica libre = time expression

Spanish word order is fairly flexible, but this order sounds natural and neutral.

You could move parts around for emphasis, for example:

• Antes de la práctica libre, hacemos el calentamiento articular.

That means the same thing, but puts more focus on the timing.

A simple pronunciation guide is:

a-SE-mos el ka-len-ta-MYEN-to ar-ti-ku-LAR AN-tes de la PRAK-ti-ka LI-bre

A few points for Spain:

• h in hacemos is silent
• c before e in hacemos is pronounced like the th in thin in most of Spain
• ll in calentamiento does not appear here, but if it did, many speakers would pronounce it like y
• Stress falls naturally on:
  • hacemos
  • calentamiento
  • articular
  • antes
  • práctica
  • libre

Yes. Calentamiento by itself already means warm-up.

So you can say:

• Hacemos el calentamiento antes de la práctica libre.

Adding articular makes it more specific:

• calentamiento = warm-up in general
• calentamiento articular = a warm-up focused on the joints / joint mobility

So the longer version gives more detail about the type of warm-up.
