Sternocleidomastoid Anatomy: Origin, Insertion & Action

[@rachrbonez1335]

awesome vid for the action of the head. i am personally here as an athlete, i've always had an issue with my clavicle when doing motions like deltoid or pec flys. now that my sport is my profession, i wanted to see if it's related to the action of the sternocleidomastoid during arm movement. the search continues but i would love if you would delve into it

Thank you! There is a lot of individuality in shapes of all the shoulder structures. For example, personally my right and left clavicle are are shaped very differently. Some people are going to have specific exercises that may cause pain, it doesn't always mean there is something wrong though, it is just something to work around. We're all built differently and mostly unsymmetrical. For your side laterals, make sure you are doing them in the scapular plane (google image search scapular plane to see what I mean), this usually fixes shoulder pain from side laterals most people. Your side delts will still be the limiting factor and sticking to the scapular plane makes the exercise easier for the shoulder joint to recover from. Also try doing them seated , with a 1sec pause at the top, with a slight forward lean, the seated position and pauses stops cheat reps and ensures you are lifting an appropriate weight and not using momentum. Seated laterals are also more stable, so this allows for a greater degree of motor unit recruitment and therefore more potential hypertrophy. As for the pec flys, you could try reducing the degree of shoulder elevation. Think of bringing them out more in line with where your nipples are or below that line, rather than up high towards your neck, if you see what I mean. You may find that allows you to do them pain free. Failing that, just swap them out for a different exercise. There is a ton of different choices for both the delts and the pecs which are just as good.

Hi Sam, glad you are enjoying the videos. I am starting a physiotherapy Master's degree this year. So I will definitely be posting some physiotherapy related content later this year! Thanks for watching.
