Physical fitness is a very big part of today's society. Not just for those directly involved in the sports industry but also for the common person. With information rife about deadly infections and bodily diseases becoming the main killers amongst us, many have opted for a healthier lifestyle with physical fitness topping the poll of being healthy.

What actually is being fit? It is the ability of the body to endure pain or not feel pain or discomfort whenever it is engaged in physical activities. There is actually five main areas in which fitness can be measured. They are :

- The ability to do some kind of physical activity that requires aerobic endurance. This helps to show how your heart is reacting and if it is, indeed, reacting well to supplying enough oxygen during the activity. Physical activities that measure this well are running, kayaking and an aerobics workout.

- Another form of fitness test is weight lifting to test muscular ability. The idea is to lift a specific weight for an amount of time. This is then repeated so that it becomes less challenging. More weight or repetitions of lifting is then added to the test until target has been achieved.

- Fitness is also assessed by muscle strength. Observe the heaviest weight that can be carried by specific body parts such as arms or leg.

- The flexibility of your limbs and elasticity of your muscles. The measurement of how supple you are generally is another measurement of your physical fitness. Along with the ability to hoist yourself up on your arms, your fitness is also judged by how easily you move from one position to another.

- The total body mass index as in the proportion of fat in your body. This is measure according to formula and is not reflected in how your look or how much you weigh. Factors that are taken into account are your height, weight and age and within certain proportions, may or may not be acceptable.

While a muscular person is more likely to be physically fit, he or she may very well just be bulky with mass but have a low fitness level. You are considered physically fit if you can satisfactorily pass all 5 levels of measurement as mentioned above.
