"Low-volume" high-intensity interval training (HIIT) of less than 20 minutes, three times a week, is as effective as the World Health Organisation's recommended 300 minutes of moderate activity a week, concludes a recent report in the Journal of Physiology.
A review of a decade's worth of HIIT studies has also found that as little as four minutes of HIIT three times a week can improve health.
HIIT has become increasingly popular as a quick and effective way to improve health, with scores of programmes and classes popping up in Hong Kong in recent years. The training incorporates short bursts of active periods of work interspersed with recovery periods.
