Improve Hamstring Strength - GHD Case Study

Improve Hamstring Strength - GHD Case Study

We introduced a banded ‘reach’ instead of the external load to increase the ability to keep the rib cage back and down (retracted) through serratus anterior engagement. This doubles as an easy way to reduce the ability of the lats to extend the spine, as the serratus anterior directly opposes the lats ability to extend the lower back (read a surplus of information on this topic by S+C GOAT - Eric Cressey). We cued an exhale at the top of the movement to draw the ribs down and pelvis up into relative posterior pelvic tilt through oblique recruitment further reinforcing the ability to control the desire to extend the system and take tension off the hamstrings. This culminated in a very tough set of 5 reps with significantly increased hamstring tension.

The rotator cuff does however have great control of the arthrokinematics (sliding, gliding rocking and rolling of the ‘ball’ on the ‘socket’) of the gleno-humeral joint throughout larger, more global movements patterns of osteokinematics. This is a result of the structure of their insertion points on the humerus:
