In many sports, strength is an extremely valuable commodity. While poise and grace are often just as crucial for success, the ability to resort to sheer force is almost a prerequisite in some of the more uncompromising disciplines.

For dedicated sport stars, the gym often becomes an obsession; somewhere to hone their physical talents and ensure that they are in pristine condition for the good of themselves and often their teammates.
It is certainly not uncommon for imposing specimens from all walks of sporting life to spend an enormous proportion of their time bench pressing and squatting for all they are worth, but it is obviously of vital importance for those who make a living in combat sports as well as the likes of American football, rugby union and even cycling.
