Answer:
When you exercise, are you working hard or hardly working? Exercising at the correct intensity can help you get the most out of your physical activity — making sure you're not pushing too hard or too little. Here's a look at what exercise intensity means, and how to maximize your workout. How hard should you be exercising? The Department of Health and Human Services recommends these exercise guidelines for most healthy adults. Get at least 150 minutes a week of moderate aerobic activity — such as brisk walking, swimming or mowing the lawn — or 75 minutes a week of vigorous aerobic activity — such as running or aerobic dancing. You can also do a combination of moderate and vigorous activity. It's best to do this over the course of a week. You can achieve more health benefits if you ramp up your exercise to 300 minutes or more of moderate aerobic activity a week.
Even small amounts of physical activity are helpful, and accumulated activity throughout the day adds up to provide health benefits.
