Rotator Cuff Muscles
Rotator cuff muscles are VERY VERY important muscles to know about. The dysfunction of these muscles can lead to a plethora of shoulder injuries ranging from bursitis, tears in the tendon and labrum, impingement, tendonitis, etc.
Do not ignore these muscles in the gym! Prior to any chest, shoulder, overhead press exercises, be sure to do 2-3 sets of internal and external shoulder rotation…Even before that, I would do some self myofascial release on the pectorals and deltoids using either a massage ball or foam roller.Releasing the pecs can really open up shoulder range of motion and mobility.
