The 21st century has become a witness to changes such as industrialization and technological advancements. These changes affect our lives in many ways. Although technological advancement and progress make certain things easier for us like household chores and office work for example, we cannot deny the fact that there are threats tied with them.

In addition, more and more people choose to neglect fitness because they are too preoccupied. A large chunk of the world’s population has very little time to exercise.
