When you properly engage in physical fitness exercises, your body will attain a high level of mental and physical health.
In fact, suitable aerobic fitness exercise will help you remove ‘bad cholesterol’ and increase ‘good cholesterol’. Moreover, the network that control blood supply in your body will get strengthened; the risk of many grave diseases will drastically reduce; the duration of existing illnesses will be significantly shortened; and infections will be prevented.
Yet, the 5 key dimensions of physical fitness exercises have different effects on different aspects of the body though they generally help the body achieve better state without taking drugs.
Strength (Muscular) Building Exercises
Here, the ability of muscles to carry heavy objects – lifting, pushing, and pulling – are developed as well as the basic walking, standing and general posture-related activities.
Usually, you can develop these muscles by engaging them in overload exercise and gradually increasing the amount of load you carry during exercise. For example, isometric exercise involves trying to lift or pull immovable objects (though it is not advisable for people with hypertension); isotonic exercise involves the use of dumbbells and other regular objects used in weight lifting; and isokinetic exercise is usually done by athletes and professionals.
Endurance (Muscular) Exercise
You can decide to improve the endurance of some groups of muscles in your body e.g. the leg muscles, abdominal mass, etc. This closely resembles cardio-respiratory endurance; it actually focuses on the ability of the muscles to withstand continuous, long term activities.
Flexibility Exercise
Joints are subject to ‘the law of use and disuse’ whereby they function less efficiently when not used regularly. This is particularly important to dancers. In physical fitness exercises, flexibility improves the efficiently of joints in the body. It also improves balance and posture.
