Go low to get the high

Low volumes of HIIT (high-intensity interval training) – clocking in at as little as four to five minutes per session – could bring big improvements in blood pressure, oxygen usage, insulin sensitivity and weight management, according to research published recently in the Journal of Physiology. You can incorporate exercises such as side lunges, press-ups and reverse lunges into a short but effective bout of low-impact, low-volume HIIT.
