Long before there have been machines to work out on and competitive sports to stay moving and before wars were being fought, man didn't think about conditioning as a way of keeping healthy. He simply knew if he didn't hunt, he wouldn't eat if he didn't run, something would hunt him. They were a down economy that focused simply on survival. Physical fitness as we know it today is miles from which it began. It began as simply survival then converted into preparation for war then began some very early competitive sports. Later it became philosophical since the body was admired for its beauty and strength. For a brief time, the main objective turned to preparation for war and after that it ventured into a medical standpoint as the great things about health and fitness came to light. Then we became sedentary and began to recognize the requirement for physical fitness in different ways. Thoughts on the other hand turned time for competitive sports and, next few centuries, evolved into the present day day revolution that people see and hear a lot about. Physical fitness has evolved in the centuries from basic survival to health awareness. Lighting- Lighting is the most main reasons of any type of photography.
