What is HIIT (high intensity interval training)?
HIIT involves brief bouts at near-maximum or maximum effort followed by periods of lower-intensity activity. Furthermore, HIIT work bouts are even shorter than “repetition” work bouts, lasting 10-20 seconds at most. Generally, the rest periods are also shorter than with all other types of cardio training. So how do you know if you’re really doing HIIT? First of all, you’re in an all-out sprint, which is impossible to maintain for more than 15-20 seconds! Light-headedness and nausea is not uncommon at this point. If done properly, total work time (work and recovery periods combined) for HIIT is never more than 15 minutes. HIIT should not be confused with “beginner intervals” or interval training. Period.
