About HIIT
HIIT (High-Intensity Interval Training) alternates short bursts of maximum-effort exercise with brief recovery periods. A 155-pound person burns approximately 295.3 calories in 30 minutes. Beyond the session itself, HIIT creates an afterburn effect — excess post-exercise oxygen consumption (EPOC) — that continues burning additional calories for hours afterward.
A typical HIIT session lasts 20-30 minutes and can include exercises such as sprints, burpees, jump squats, and mountain climbers. HIIT is one of the most time-efficient training methods for improving cardiovascular fitness and body composition.
