Exercise is really important in our lives but some people have reasons to just not do it. Sometimes in many cases, people don’t have much motivation. These are some studies found on Los Angeles Times that have shown up to show the many important reasons of exercising.

• Exercise Slows the Aging Process: Aging muscles have trouble regenerating and have fewer and less efficient mitochondria, the energy powerhouses of our cells. But exercise, especially when it’s high intensity, increases the number and health of mitochondria — essentially helping to reverse aging at the cellular level.
• People Who Exercise Are Happier: Exercise can alleviate symptoms of depression and help you better cope with stress and anxiety. Even just getting up and moving around may make you feel happier, studies show.
• It May Lengthen Your Lifespan: Exercise has been linked time and time again in studies both large and small to reductions in mortality from all causes. But some of the most fascinating research comes from extensive analyses carried out at the Cooper Institute in Dallas, which show that compared with non runners, runners tend to live about three years longer. Every hour of running you do adds an estimated seven hours to your life expectancy. In fact studies have found that as little as five minutes of daily running is associated with longer life spans.
• Exercise Improves Your Body Composition: Most people gain fat as they get older. It’s essentially inevitable. But lifting weights and following a good diet have the opposite effect: They help you put on muscle and lose fat, even if you are older than 60.
• It Can Boost Your Brain Health: Studies of aerobic exercise have found that it protects your memory and helps stave off cognitive decline as we age.
• Exercise Improves Your Microbiome: Studies show that exercise can drastically improve the composition of the trillions of microbes that live in the gut, which may be one reason it strengthens the immune system, fights inflammation and helps with weight control.
