If you've been wondering what HIIT is but were always too afraid to ask, here’s your answer: it stands for "high-intensity interval training". FitBuzz HiiT classes involve a period of working hard, followed by a period of much lower intensity – or complete rest. This is then repeated for a number of rounds or for a duration of time. We do bursts of cardio exercises like jacks and spot sprints and strengthening exercises like squats and press-ups.
