According to a study recently published in The BMJ, adding high-intensity interval training to one’s daily routine can have a tangible impact on longevity.
Exercise scientists from the Norwegian University of Science and Technology recruited 1,500 septuagenarians from the city of Trondheim, Norway, to exercise at various clips for five years. The first group (the control) agreed to walk for about a half hour each day. The second group exercised for sessions of 50 minutes each day. The third group started a biweekly HIIT program, which followed a “four, four, four” format: four minutes of strenuous exercise, four minutes of rest, four times through.
