The Strongest Muscle Depends on How You Measure It

People often argue about the “strongest muscle,” but the answer changes depending on how strength is defined.

  • By force output, the jaw muscle (masseter) ranks near the top
  • By endurance, the heart never stops working
  • By size relative to force, some muscles in the calf outperform larger muscles

So when someone claims a single muscle is the strongest, they’re usually only telling part of the story.
