Coach Greg Glassman breaks down the significance of the overhead lifts that progress from shoulder press, to push press, to push jerk. From shoulder press to push jerk the movements become increasingly more athletic, functional, and suited to heavier loads
These lifts are enormous aids to developing the power zone (hip flexors, hip extensors, spinal erectors, and quadriceps). As the athlete progresses through the lifts, the importance of core to extremity muscle recruitment is learned and reinforced. This is foundational to the effective and efficient performance of athletic movement, and alone would justify the practice and training of these lifts.
Mastering this progression allows detection and elimination of common postural/mechanical faults. The pelvis “chasing” the leg during hip flexion and other common faults plague more athletes than not.
The ability of the abdominal muscles to maintain midline stability becomes critical when driving loads overhead. The role of the hip is increased in each exercise to assist the arms and shoulders in lifting the load overhead. After mastering the push jerk you will find that it unconsciously displaces the push press as your method of choice when going overhead.
