The definition of fitness has changed quite a bit over the years. Originally, physical fitness was defined as being in good overall health, with no limitations. More recently, physical fitness has been defined as the capacity to do activities of daily living and, in particular, the capacity to carry out certain types of jobs, sports and other physical activities. Physical fitness is usually achieved through regular weight lifting, proper nutrition and adequate rest.
The key components of a physically fit body are muscle strength, speed, endurance, and flexibility. It is estimated that most people in the United States possess at least one of these key components. Although some people may possess all three components, they are not considered to be in the best shape if they do not have all three. Therefore, it is important to make sure that you have the components of a muscular body, which are defined as follows:
Aerobic fitness is an exercise activity that increases your heart rate and improves your lung capacity and your endurance. This type of physical activity can be done by doing cardiovascular exercises such as running, walking, cycling or swimming. Most cardiovascular exercises require a considerable amount of time and effort to be effective. However, if you want to get fit quickly, then this should be a preferred option. Additionally, you can also opt to do aerobics and weight training instead of doing the cardiovascular exercises.
Muscular endurance is the ability of the skeletal muscles to sustain tension. It is an important factor for weight lifting, because if you do not have enough muscular endurance, then you will not be able to lift heavy weights. Muscular endurance is also an important aspect of a muscular body. There are different forms of muscular endurance such as, passive resistance or dynamic strength. If you want to develop this area of your body, then you can go for push-ups, pull-ups, bench press and squats.
Finally, muscular endurance is associated with your body composition. If you have a high percentage of body fat, then you are less likely to have high muscular endurance levels. However, if you have a high percentage of body muscle mass, then you will be more likely to have high overall health.
Regular physical activity is essential to maintaining a healthy well-being. Physical fitness helps you to reduce your risk of heart disease, diabetes, stroke, hypertension, obesity, osteoporosis, and some forms of cancer. It also helps to keep depression at bay and maintain your energy level even when you are under severe stress. You can also reap long-term benefits from fitness activities by reducing your dependence on daily tobacco products, preventing joint disorders, and improving your cognitive function.
