The strengthening of the four muscles that comprise the rotator cuff is often over
looked in most recreational lifters resistance training programs. The
infraspinatus, teres minor, supraspinatus, and subscapularis are responsible
for stabilizing the humerus in the glenoid fossa. When the muscles are
overlooked for specific strengthening the humerus can move up and down inside
the fossa causing bone spurs, deterioration of the cartilage in the joint, as
well as tearing of labrum. This can cause severe pain and loss of motion in the
shoulder complex. Specific training of these muscles can be easily accomplished
with a simple program of three exercises. These can be completed in any gym or
home setting with or without resistance. The three exercises shown should be
started in a program with 2-3 sets of 10-15 repetitions.
