In a busy world with work demands, family obligations and seemingly endless to-do lists, it can be hard to find any time to exercise — let alone hit the (fairly intimidating) recommended amount per week.
Less than 25% of Americans meet the country’s physical activity guidelines, which state that adults should get at least 150 minutes of moderate-intensity exercise (such as brisk walking, gardening, doubles tennis) each week or 75 minutes of vigorous-intensity exercise (such as running, swimming laps or hiking uphill) and do at least two days of strength training each week.
But new research out of Norwegian University of Science and Technology suggests you may not need to exercise that much to see health benefits — that is, if you’re working out hard. Researchers found that just 30 minutes of high-intensity exercise per week (yes, per week) is good for your health, specifically heart health.
