Full origin of HIIT →Frequently asked questions
What is the difference between HIIT and ordinary cardio?
Ordinary, or steady-state, cardio holds one moderate effort level for the whole session, such as a half-hour jog at a constant pace. HIIT instead alternates very hard efforts with recovery periods, so the intensity rises and falls repeatedly. The two differ in structure, not in the equipment used.
How long is a HIIT session?
Sessions are usually short compared with steady-state training, often between ten and thirty minutes including the intervals and the rests. The length depends on how many rounds are done and how long each work and rest period lasts. There is no single fixed duration that defines the term.
Does HIIT have to involve running?
No. The term describes the interval structure rather than any one activity, so cycling, rowing, swimming, skipping and bodyweight circuits can all be organised as HIIT. What makes it HIIT is the alternation of hard effort and recovery.
