Italian Phrase
Fai HIIT oggi?
Meaning
‘Are you doing HIIT today?’ – a casual way to ask a friend or workout partner if they plan to perform a high‑intensity interval training session today.
When to use
Use this phrase in informal settings: with gym buddies, on a fitness‑app chat, or when you’re coordinating a group workout. It’s too informal for a trainer‑client relationship unless you already have a friendly rapport.

✕Common Mistakes
Sei HIIT oggi?
Use *fare* (fai) for activities, not *essere* (sei).
Fai HIIT adesso?
While grammatically correct, *adesso* (right now) changes the nuance; the original phrase asks about the whole day, not the immediate moment.
Fai HIIT oggi
Missing the question mark or rising intonation can make it sound like a statement rather than a question.

Cultural Tip
HIIT has become a buzzword in Italian fitness circles, especially among younger people. Borrowed English acronyms (HIIT, CrossFit, Zumba) are widely understood, but keep the tone informal. If you’re speaking to an older person or a professional trainer, replace *fai* with *fa* (third‑person) or use a more formal structure: *Sta facendo HIIT oggi?*
