Triple-Flexion is when the ankle hinge, the knee hinge, and the hip hinge are all flexed together.  A classic example of this is seen when you do a squat.

Squat Triple-Flexion: ankle, knee, and hip flexing together.

Triple-flexion is a basic human movement that is necessary not only in sports but in your day to day life.  You are probably doing it right now sitting in your chair reading this!  Here are some examples of when you do it at the gym:

  • If you’re at risk for injury
  • What faults are holding you back from a great squat pattern
