First, it is important to understand exactly what the phrase "physical fitness" means. Contrary to what many might think, exercising is not enough to truly be physically fit. Instead, fitness is much more comprehensive. It refers to a person's overall strength, flexibility, aerobic ability, and endurance. While exercise plays a key role in improving each of these, other factors, like not smoking, are also essential to optimal physical fitness.
One benefit of physical fitness is that it results in strong bones. Strength training, most often associated with building muscle, is also responsible for improving and maintaining bone density over time. In fact, physical fitness is directly associated with a decreased risk for osteoporosis, especially in women. Additionally, being physically strong makes daily tasks easier and guards joints against major injuries.
Physical fitness also makes it easier to lose weight. When a person is in shape, he or she has increased muscle mass. Since muscle burns more calories than fat, this means an individual's body uses up more calories and stores less of them as fat. Lower body fat is also associated with a longer lifespan, and this is not the only way that physical fitness can improve longevity.
Improving aerobic fitness through physical activity is a great way to protect both heart and lung health. In fact, individuals who participate in a physical fitness regimen are less likely to fall victim to heart disease or other common, and often serious, health complications. With heart attacks among the top causes of death in the United States, keeping one's heart in top condition is vitally important. Meanwhile, physical fitness also improves lung function and can reduce the discomfort associated with common respiratory diseases like Asthma, which can also lead to other health complications.
Ultimately, physical fitness can improve almost every aspect of a person's daily life. Endurance means working is easier and walking is more pleasurable. Meanwhile, aerobic ability makes breathing easier and can particularly help an individual who like to swim or hike. Overall, physical fitness is vitally important as it can help someone do everything from carry groceries to play with their kids to climb a mountain.
