Description:

The quadruped hip extension teaches the body how to fire the glutes instead of compensating with lower back extension. This enhanced lumo-pelvic awareness and control will result in better performance throughout your global kinetic chain. 

Technique:

Assume a 4 point kneeling position
Arms straight underneath shoulders
Knees directly under hips 
Lower back with slight natural curve which is maintained throughout set
Bend working leg to 90 degrees of knee flexion
Extend the hip until the lower back feels like it will arch
