According to the Merriam-Webster Dictionary, to be fit is to be “sound physically and mentally.” Physical fitness is measured through flexibility, muscular strength, muscular endurance, cardiovascular endurance, and body composition. These components may appear intimidating at first, however, simply getting up and exercising daily will satisfy being fit! Involving fitness into a regular lifestyle is not difficult at all. Spending at least 30 minutes a day exercising the body will lead to incredible results. Simple exercises include yoga, riding a bike, going for a run, taking a trip to the gym, or playing a sport. Exercise has many great impacts on the human body including reducing inflammation and triggering the growth of the brain. It is beneficial to practice lifelong fitness because it will extend one's lifespan by slowing down aging.

One major result that physical fitness has on the body is that it reduces inflammation which is the underlying cause of various diseases and disorders impacting the body and brain. Some of the major diseases that possibly begin with inflammation are multiple types of cancer and diabetes. Forbes Magazine writes in an article about Suzi Hong, a doctor who studies exercise and immune system activation at the UC San Diego School of Medicine. In the article “6 Science-Backed Ways Exercise Benefits the Body and Brain” they state, “A new study from her lab shows that a 20-minute moderate workout has measurable effects on the immune system: Participants were asked to walk or jog on a treadmill, depending on their fitness level. They measured levels of TNF, an inflammatory marker, before and after the exercise, and found that there was a 5% reduction in the number of immune cells that produced the marker.” By maintaining daily exercise, the inflammation of the body will never grow to a point where many diseases thrive. It does not entirely prevent them, but by continuing habits of exercising daily, the less likely one will be to have a disease because of smaller amounts of inflammation.

Furthermore, another major result that physical fitness has on the body is that it triggers the growth of new brain cells. At first, neuroscientists did not believe that the brain could produce new cells, but in recent years they realized that it is possible for the brain to produce neurons through a process known as neurogenesis. In the article “6 Science-Backed Ways Exercise Benefits the Body and Brain,” Forbes Magazine writes, “The area of the brain that seems most capable of growing new cells is the hippocampus, the seat of learning and memory. It's also the area that’s known to “shrink” in depression, and particularly in dementia …” This occurs during aerobic exercises, and helps many stay out of depression and strengthen their memory. This is beneficial for young adults because that is when depression seems the most prominent in life, and at the same time it is also beneficial to the elderly because dementia is a serious disease that causes them to forget in later stages of life. The growth of the brain has many amazing effects on the body which all sprouts from simply exercising!

On top of these wonderful effects that exercise has on the body, it is important to maintain a lifelong practice of fitness because it will lengthen one’s lifespan by slowing down the aging process. New studies have recently shown that practicing lifelong fitness can extend someone’s lifespan to a maximum of five years, all beginning at a cellular level! Mandy Oaklander and Heather Jones, two writers for Time Magazine, wrote in an article about researchers conducting experiments on exercising humans. In the article “7 Surprising Benefits of Exercising,” they write, “… researchers took a muscle biopsy and blood samples from 10 healthy people before and after a 45-minute ride on a stationary bicycle. They found that exercise increased levels of a molecule that protects telomeres …” When telomeres decay away and grow old, so does the human which is why the protection of them causes longer life. The main way to protect telomeres sprouts from fitness over the course of time. Exercising only once will not preserve these important cells. In order to maintain this extension of life, exercise must constantly be practiced over the course of a lifetime.
