THE INTERACTION OF LATISSIMUS DORSI MUSCLE, TERES MAJOR MUSCLE AND PECTORALIS MAJOR MUSCLE ⠀ [ANATOMY, FUNCTION & TRAINING ADVICE] ⠀ Did you know that latissimus dorsi, teres major and pectoralis major are actually connected!? ⠀ On pic 1 you can see all 3 muscles which belong to the same fascial connection: THE SUPERFICIAL FRONT ARM LINE (SFAL). ⠀ On pic 2 you can see exactly that latissimus dorsi and pectoralis major join in the medial intermuscular septum of the arm which is further connected to the forearm flexors and the palmaris longus including the carpal tunnel. ⠀ If you suffer from neck or shoulder problems (Rounded shoulders) always make sure to treat these muscles in the right way! ⠀ Latissimus dorsi, teres major and pectoralis major are medial rotators of the humerus, that means that if you overtrain these structures, it will force rounded shoulders! ⠀ I am specifically mentioning this because of how many people you see in the gym doing bench press and lat pulldown all training session long without doing any stretching or exercises to keep the shoulder girdle in balance! ⠀ Even if you don't suffer from any problems or pain right now, but you train in the wrong way over a period of time you can train yourself into a misalignment which will lead to shoulder, cervical/thoracic spine problems, tension in upper traps or headaches! ⠀ Especially for those who spend the majority of their day sitting, such as office workers or those who spend the majority of their day in a hunched position such as dentists, it is very important to train the right way. Being in a poor position and using these muscles will cause an adaptive shortening and tightness already! ⠀ Nevertheless important for therapists is to do a proper diagnose and find out if a muscle is facilitated or inhibited and then to release or strengthen it to get the right balance!
