We all know that exercise is important in our daily lives, but we may not know why or what exercise can do for us. Here are some benefits of exercise.

Exercise increases energy levels. Exercise improves both the strength and the efficiency of your cardiovascular system to get the oxygen and nutrients to your muscles. When your cardiovascular system works better everything seems easier and you have more energy for the fun stuff in life.

Exercise improves muscle strength. Staying active keeps muscles strong and joints, tendons, and ligaments flexible, allowing you to move more easily and avoid injury. Strong muscles and ligaments reduce your risk of joint and lower back pain by keeping joints in proper alignment. They also improve coordination and balance.

Exercise can help you to maintain a healthy weight. The more you exercise, the more calories you burn. In addition, the more muscle you develop, the higher your metabolic rate becomes, so you burn more calories even when you're not exercising. The result? You may lose weight and look better physically which will boost your self-esteem.

Exercise improves brain function. Exercise increases blood flow and oxygen levels in the brain. It also encourages the release of the brain chemicals (hormones) that are responsible for the production of cells in the hippocampus, the part of the brain that controls memory and learning. This, in turn, boosts concentration levels and cognitive ability and helps reduce the risk of cognitive degenerative diseases such as Alzheimer's.
