Exercise aims to maintain or enhance an individual's physical fitness and health in general, according to Medical News Today. It comes in different forms and ways, like swimming, biking, running, lifting weights at the gym or walking in the park.

There are many different reasons why people exercise. It includes strengthening the muscles, honing athletic skills, controlling bodyweight, release stress, for socialization, etc.

What are the benefits people can get from it? Let's go ahead and find out.

Older People

1. Reduce the risk of injuries and depression

People are exercising more in their later years because studies have shown it reduces the injury risk to joints and tendons, according to Delaware Online. At the same time, it lowers the risk of having an arthritis.

In addition to maintaining aerobic capacity, muscle strength and bone density, regular exercise among older people reportedly decreases the risks of depression and cognitive impairment.

The communities of 55 years old and older doing different physical activities, are now growing. Having this kind of community reportedly helps senior citizens stay fit.

It is important, though, to consult a doctor first before jumping into fitness programs — this doesn't only pertain to older people, but to any age levels.

Women

2. Improve fertility chances among overweight women and those diagnosed with Polycystic Ovary Syndrome (PCOS)

There are supporting studies, as per Tech Times, showing that losing as little as five percent of bodyweight can improve chances of getting pregnant. Out of 50 women who underwent a combination of birth control, healthy diet and exercise 12 had successful pregnancies.

The research suggested that a combined lifestyle change and birth control had increased their chances of ovulation compared to those who had birth control alone.

Teens

3. Reduces suicide attempts among bullied teens

A new study from the University of Vermont suggests that encouraging exercise of at least four times a week among bullied students reduces the number of suicide attempts and ideation by 23 percent, iSchool Guide reported.

"I was surprised that it was that significant and that positive effects of exercise extended to kids actually trying to harm themselves," Jeremy Sibold, Department Rehabilitation and Movement Science chair and associate and lead author of the study, said.
