A Primer, Bodyweight Basics

ROTATOR CUFF
The muscles of the rotator cuff are also helpful to examine, as they are responsible
for stabilizing the ball and socket joint which is your shoulder. To compensate for
the huge range of motion the shoulder is capable of, it relies on the support of the
rotator cuff muscles to keep it structurally sound.
They are as follows: Supraspinatus, Subscapularis, Infraspinatus and Teres Minor.
The Supraspinatus assists the
Delts in lifting the arm away
from the body, e.g. front and
lateral raises. This process is
also known as abduction.
The Subscapularis rotates the
arm medially, like holding a
drink in front of you.
The Infraspinatus rotates the
arm laterally, which is out to
the side. The Teres Minor also
assists in this range of motion.
Proper scapula control drastically reduces the
chance of injury.
To put it simply we are trying to go against what
gravity wants us to do, as we need to STABILIZE
the scapula, not be limp. Fight back.
In general if we are pulling, RETRACT.
If we are pushing we should be PROTRACT-
ING.
