It's vital that we continue to challenge ourselves to keep our bodies mobile and our minds sharp as we age. While swimming workouts or a quick 15-minute walk will certainly help get your heart rate up and improve longevity, only one type of exercise has been proven to boost cardiorespiratory fitness and quality of life.
The Norwegian Generation 100 study reviewed more than 1,500 men and women between 70 and 77 years old for five years. They studied the effects of exercise and the difference between moderate and high-intensity training among the participants. The results, published in the British Medical Journal, found that high-intensity interval training (HIIT) was the most effective for improving fitness and quality of life with age.
