Strongest muscle

The strongest muscle in the human body is the masseter (one on each side of the mouth) which is responsible for the action of biting.   In August 1986, Richard Hofmann (USA) (b. 1949) of Lake City, Florida, USA, achieved a bite strength of 442 kg (975 lb) for approximately 2 seconds in a research test using a gnathodynamometer at the College of Dentistry, University of Florida, USA. This figure is more than six times the normal biting strength.
