The human body is a large collection of levers. Every muscle pulls on a lever to make it move. We know all the large levers. They create visible movement. They move our legs, bends our knees, raises our arms.

It creates the impression that one simple lever is accomplishing these monuments tasks. Large levers have inherent vulnerabilities.

  • They operate in only one direction. Since most movements require complex trajectories, a single muscle would never be able to perform the job.
  • They are unstable and vulnerable to any lateral movement. Ask any athlete who has torn cross-ligaments in the knee.
  • During the range of motion, at full extension, the movement is particularly vulnerable to directional forces.

The fix is simple. Introduce many small levers. They resolve most of these inherent risks and ensure a smoothe, support, fluid motion. That is if they are strong enough to do the work.

Mostly, we focus on the levers that look impressive. We lose sight of the hidden, critical levers that ensure successful execution and sustainability over time.

Creating single levers systems is appealing but rarely worth it.
