It can contribute to heart disease, type 2 diabetes, several cancers, and obesity. In addition, low levels of physical activity are associated with $117 billion in health care costs every year.

Regular physical activity can improve your muscle strength and boost your endurance. Exercise delivers oxygen and nutrients to your tissues and helps your cardiovascular system work more efficiently. And when your heart and lung health improve, you have more energy to tackle daily chores.

Regular exercise and physical activity promotes strong muscles and bones. It improves respiratory, cardiovascular health, and overall health. Staying active can also help you maintain a healthy weight, reduce your risk for type 2 diabetes, heart disease, and reduce your risk for some cancers.

Positive effects from sports are achieved primarily through physical activity, but secondary effects bring health benefits such as psychosocial and personal development and less alcohol consumption. Negative effects, such as the risk of failure, injuries, eating disorders, and burnout, are also apparent.

Exercise while ignoring your diet just isn’t a good weight loss strategy, says exercise physiologist Katie Lawton, MEd. “To lose weight, you need to burn more calories than you consume or eat fewer calories than your body uses each day,” says Lawton. “If you don’t have a caloric deficit, you will not lose weight.”

Without exercise, your metabolism likely will slow down. A speedier metabolism is one reason why exercise is a natural companion to eating less for weight loss. Depending on how much you exercise, it can help you lose weight more quickly.

As long as you’re not pushing yourself too hard or getting obsessive about it, working out every day is fine. Make sure it’s something you enjoy without being too strict with yourself, especially during times of illness or injury.

It’s recommended to take a rest day every three to five days. If you do vigorous cardio, you’ll want to take more frequent rest days. You can also have an active rest day by doing a light workout, like gentle stretching. To determine when you should rest, consider the recommendations for aerobic activity.

Exercise is supposed to be good for you — but exercising too much or running too fast can have serious consequences for your body and brain. Over-exerting yourself could actually undo the results you worked hard to get, and worse, could damage your heart and arteries, lead to injuries, and make you addicted.
