Podemos trotar e hidratarnos juntos.

Podemos is the present tense, nosotros form of poder: we can / we are able to.

So:

• puedo = I can
• puedes = you can
• puede = he/she/it can
• podemos = we can
• podéis = you all can
• pueden = they can

In this sentence, podemos introduces what we can do: trotar e hidratarnos.

After poder, Spanish normally uses another verb in the infinitive.

So the pattern is:

• poder + infinitive

Examples:

• Podemos trotar = We can jog
• Puedo comer = I can eat
• Puedes venir = You can come

That is why you get:

• podemos trotar
• podemos hidratarnos

rather than conjugating those verbs again.

Spanish normally uses y for and, but it changes to e before a word that begins with an i- sound to avoid an awkward repetition of sound.

So:

• padre e hijo
• España e Italia
• trotar e hidratarnos

Even though hidratarnos starts with h, the h is silent, so the word begins with an i sound: idratarnos.

That is why e is used here, not y.

Because hidratarse is a pronominal verb here, and the pronoun nos can be attached to the infinitive.

So:

• hidratarse = to hydrate oneself / to get hydrated
• hidratarnos = to hydrate ourselves

With infinitives in Spanish, object or reflexive pronouns are often attached to the end:

• lavarse
• moverse
• hidratarnos

You could also place the pronoun before the conjugated verb in some structures:

• Podemos hidratarnos
• Nos podemos hidratar

Both are grammatical. In your sentence, attaching it to the infinitive is completely natural.

Literally, it means to hydrate ourselves.

In natural English, that often means:

• to drink water
• to rehydrate
• to stay hydrated

In Spanish, hidratarse is common in health, fitness, and sports contexts. It sounds a bit more formal or “wellness-oriented” than simply saying beber agua.

So in everyday conversation, a Spaniard might also say:

• Podemos trotar y beber agua juntos.

But hidratarnos is still perfectly understandable and natural, especially in an exercise context.

Trotar usually means to jog or to trot, so it suggests a lighter, steadier pace.

Correr means to run, which is broader and can include jogging, running fast, racing, and so on.

So:

• trotar = jog
• correr = run

If the sentence is about light exercise, trotar fits very well.

Juntos means together, and here it modifies the whole action: jog and hydrate together.

In Spanish, adverbs and similar expressions of this type can often be placed after the verbs quite naturally:

• Podemos comer juntos.
• Podemos salir juntos.
• Podemos trotar e hidratarnos juntos.

Putting juntos at the end sounds very normal.

Because juntos/juntas agrees with the people being referred to.

• juntos = masculine plural, or a mixed group
• juntas = feminine plural

So if the speaker is talking about:

• a mixed group or two people of different genders → juntos
• a group of only women → juntas

Since the sentence uses nosotros implicitly through podemos, juntos is the default unless the group is entirely female.

The h in Spanish is silent, so hidratarnos is pronounced roughly like:

• ee-dra-tar-nos

The h is not pronounced at all. That is also why e is used instead of y: what matters is the sound, not just the spelling.

So although it is written hidratarnos, it begins phonetically with an i sound.

Yes. That would be a very natural alternative.

The difference is mainly one of style:

• hidratarnos = a bit more health/fitness-oriented, slightly more technical
• beber agua = simpler, more everyday

So both work, but they feel a little different:

• Podemos trotar e hidratarnos juntos. = We can jog and hydrate together.
• Podemos trotar y beber agua juntos. = We can jog and drink water together.

Yes, to some extent. Spanish word order is flexible, though some versions sound more natural than others.

Natural options include:

• Podemos trotar e hidratarnos juntos.
• Nos podemos hidratar y trotar juntos.
• Podemos trotar juntos e hidratarnos.

However, the original sentence is smooth and clear. It presents the two actions first and then adds juntos, which sounds very natural.

It works across the Spanish-speaking world. Nothing in Podemos trotar e hidratarnos juntos is uniquely from Spain.

A few notes:

• podemos and juntos are universal
• trotar is widely understood
• hidratarse is also widely understood, especially in health or exercise contexts

So a learner of Spanish from Spain can safely use it, and speakers from Latin America would understand it too.
