The sport of weightlifting requires speed, strength, coordination, and mobility all packed together with skill. Anyone can pick something off the floor, but picking something heavy up and lifting it above the head is much more difficult. Even the strongest individuals can only lift heavy weights so far off the floor. Therefore, in order to lift, you have to get under the bar. And do it quickly under time constraints. This is the essence of weightlifting and distinguishes it from the other ‘strength’ sports such as powerlifting and strongman.
