VaifazerHIIThoje?
Ir + infinitivo (futuro próximo)
‘Vai’ is the third‑person singular present of ‘ir’ used with an infinitive to express a near‑future action, similar to ‘going to’ in English.
Infinitive ‘fazer’
‘Fazer’ means ‘to do/make’; when paired with ‘ir’, it indicates the activity you plan to perform.
Acronym ‘HIIT’
HIIT stands for High‑Intensity Interval Training; it is treated as a masculine noun in Portuguese, so the article is omitted in this question.
Adverb of time ‘hoje’
‘Hoje’ means ‘today’ and usually appears at the end of the sentence for emphasis.
Question intonation
In spoken Portuguese the rising intonation at the end signals a yes/no question; the written question mark reinforces this.

✕Common Mistakes
Faz HIIT hoje?
Using ‘faz’ (third‑person singular of ‘fazer’) turns the sentence into a statement; you need ‘vai fazer’ to ask about a future intention.
Vai fazer o HIIT hoje?
The article ‘o’ is unnecessary because ‘HIIT’ is treated as a proper noun/acronym, not a regular masculine noun.
Vai fazer HIIT agora?
‘Agora’ means ‘now’; the original phrase asks about today, not the immediate moment.

Cultural Tip
HIIT has become extremely popular in Brazil’s fitness scene, especially in urban gyms and online classes. When you ask about HIIT, it’s common to follow up with a suggestion for a specific app or a local studio. Keep the tone light; Brazilians often mix fitness talk with friendly banter, so a smile or a quick “Vamos juntos!” (Let’s do it together!) is well‑received.
