New research, published in The Lancet, set out to answer this question.

World Health Organisation guidelines recommend a minimum of 30 minutes of "moderate-intensity aerobic physical activity" five days a week, but whether less exercise than the recommended 150 minutes a week and whether different types of exercise can have life expectancy and other health benefits is unclear.

So, the Canadian study tracked the exercise patterns and life expectancy of more than 130,000 adults from 17 different countries over the course of six to nine years.
