Three incredible things come together when Usain Bolt runs the 100 meter.

  1. Because he is taller than many of his competitors, his stride is longer than theirs. He averages 41 strides to their 44 strides.
  2. But, because he is taller, he weighs more and needs more force. This force comes from weight lifting.
  3. Third, he needs to precisely control his movements to have his legs and feet move in harmony and avoid any missteps. This relies on the connection between his brain and his leg muscles.
