Most adults are busy with work or family obligations, so exercising can be difficult to do every day. A new study published in the journal JAMA Internal Medicine shows that weekend warriors who do all their physical exercise at once rather than over the course of the week can still get the same benefits, at least in terms of lowering their risk of early death. Brazilian researchers studied over 350,000 people and found that there was no real difference in all-cause mortality between those who exercise regularly and weekend warriors, as long as they were getting the same amount of moderate to vigorous physical activity in a week. Adults should aim to get at least 150 minutes of physical activity and two days of muscle strengthening activity a week.
