Staying fit for life requires dedication and commitment. There is much more to it than having a healthy body mass index, or muscles in all the right places. Assessing how fit you truly are requires a careful understanding of different concepts, which we know as the 5 core components of fitness. All of these play an equally important role in your overall health, so if you want to achieve genuine health, it’s best to understand all of these.

Cardiovascular endurance: Being able to sustain cardiovascular or aerobic exercises for at least 90 minutes constitutes cardiovascular endurance. Commonly referred to as cardio, these kinds of exercises are extremely effective in getting rid of unwanted fat and keeping the rest of the body healthy. Even if you have well-defined muscles, it means nothing if you can’t jog for 20 minutes straight. Cardiovascular endurance is a measure of how efficiently your lungs, vascular system, and heart are all working to deliver oxygen to the bloodstream.

Cardiovascular endurance is a vital aspect of fitness because it is a reflection of how healthy your lungs, vascular system, and heart are. Being able to show high cardiovascular endurance during activity also means that your organs are just as healthy even when you are resting or sleeping. It is also a sign that there is significantly less stress on your heart which can help you prevent illness and strengthen the immune system.

Muscular strength: This refers to the amount of force you can resist by using your muscles during anaerobic activities for short periods of time. You can test your resistance levels by lifting household objects or using bodyweight exercises right from home. The most effective way to improve muscular strength is through functional training exercises or those that resemble the basic tasks that you do daily (also known as activities of daily living or ADL) or in sports that you are active in.

To measure your muscular strength, you should be able to gauge how efficient you are when performing various ADLs. However, ADLs will differ with each individual but there are general functional exercises that can benefit everyone. These include pull-ups, pushups, and lifting a variety of heavy objects.

Muscular endurance: Muscular endurance refers to anaerobic activities and muscle contractions that are less than 90 seconds. This component of fitness is important because it is through muscular endurance that you can achieve both cardiovascular endurance and muscular strength. Muscular endurance is necessary for one to achieve a healthy, well-functioning cardiovascular system.

You can increase muscular endurance by working out using light weights with 20-25 reps each time. Light weights, as opposed to heavy weights, are more effective for improving muscular endurance because they train the specific muscle fibers that are required for muscular endurance.

Flexibility: Often one of the most underrated components of physical fitness, flexibility plays several important roles in fitness.  It refers to the ability of the human body to easily move ligaments, muscles, and joints using their full range of motion without experiencing pain or discomfort.

Flexibility is important not just for performing daily tasks or carrying objects such as bags when we go to work. It’s necessary for maintaining the overall health of your joints and protecting them. Flexibility also protects the lower back and reduces the risk of arthritis as well as any injuries to the tendons and muscles. The most effective and simplest way to improve flexibility throughout the body is through regular stretching. A common method used to test for flexibility is by asking a person to sit and try to touch their toes. People with good flexibility will be able to reach for their toes easily and without any trouble.

Limited or poor flexibility can lead to several health problems and can also affect the other components of fitness.

Body composition: This refers to how much fat your body has compared to lean body mass, which refers to bones, muscles, ligaments, tendons, and organs. Body composition is used to indicate overall fitness instead of using body weight. For this reason, it isn’t reliable to use a scale to determine how much lean body mass or fat your body actually has.

Body composition is a vital component of fitness because it directly affects one’s risk of developing illness. It’s important to maintain a good ratio of lean mass to fat mass. The recommended body fat composition for a healthy male is 17% and below, while for women it’s 24% and below.

Improving the other components of fitness will positively affect your body composition which means that you will have less fat. Having a high body fat content will increase your chances of becoming overweight or developing obesity, which puts you at risk for disease.

To effectively decrease your body fat, regular aerobic exercise will be beneficial for reducing body fat while increasing muscle mass. Doing so will improve overall body composition and will also contribute to general health and fitness.

Each of these components is equally important; one of them shouldn’t be seen as more important than the other. To achieve optimal health and fitness, it is important to understand that these components depend on each other and develop the appropriate exercise regimen to address the weakest aspect. You can have a healthy body composition but if you are unable to walk up the stairs without losing your breath, it means that you need to improve cardiovascular endurance with the right fitness plan.
