Physical fitness is the ability to meet the ordinary and unusual challenges of daily life without becoming overly fatigued and to meet the average physical stresses of emergency situations. There are five basic aspects to physical fitness. One example is aerobic endurance. This is the ability to do moderately strenuous activity over a period of time. Muscular endurance is another aspect of physical fitness. This is the ability to hold a particular position for a sustained period of time or repeat a movement many times. Another aspect of physical fitness is muscular strength, which is the ability to exert maximum force, such as lifting the heaviest weight you can, one time. A fourth aspect of physical fitness is flexibility. This is the ability to move a joint through its full range of motion. The final aspect of physical fitness is body composition. This is the proportion of fat in your body to lean tissue.
There are endless benefits of being physically fit. Being fit and exercising increase the amount of endorphins released into your body. This is one reason that being physically fit makes you feel happier. Also, it shows that exercise can help you handle stress. Increasing your muscular strength also includes the strengthening of connecting tissues such as ligaments and tendons. This greatly reduces the risk of sports or other activity-related injuries. A person who is physically fit would be less likely to sprain a muscle or break a bone than a person who leads a sedentary lifestyle. By building muscle, you increase your basal metabolic rate (BMR) even when you are at rest. Basically, this means that you get more muscle and burn more calories. Exercise is an important factor in losing weight. This can be achieved by twenty to thirty minutes of moderate exercise three to five times a week. This helps burn fat. Exercise also helps people to quit smoking. Studies have shown that exercise makes quitting smoking easier and helps increase success rate.
