What is Powerlifting? The technical definition of Powerlifting is: "A competition or sport involving three tests of strength: the bench press, squat, and two-handed dead lift." according to Dictionary.com. For most, the definition translates to: "A Neanderthalic activity for meat heads where heavy weight is picked up and put down repeatedly." The sport proves to be much more complicated and technical than it first appears. It deals greatly with complex bio-mechanics and the important physics concepts such as moments, forces, and gravity.
