Hell there, I have an issue in any kind of exercises involving the Overhead Position (Overhead Press e Overhead Squat).
Precisely, at the Overhead lockout position (shoulder blades elevated and arms slightly internally rotated) I cannot keep the barbell in the frontal plane, but rather it rotates so that it is in front of the mid-foot on the right side and behind the mid-foot on the left. I tried to let it be visualized in the following picture:
This implies that:
in the lockout position of the Overhead Press, my torso is slightly twisted (although I still can get a stable lockout in this exercise).
in the Overhead Squat, during both the way up and down, the weight shifts continuously from my heel to my toes and viceversa, because I can't get balanced during the movement. I think this is caused by the barbell rotation described above.
So, I wanted to ask you if you have some tips to fix it. I've noticed that, if I perform both exercises with the Kettlebells, this problem disappears and I'm quite symmetric. But when I get the barbell, it causes a rotation of my torso and it stays as depicted above. Moreover, I've noticed that such a rotation increases with the load. But also with a 15kg barbell it exists.
I do not know which muscle unbalance causes it, so I wanted to know if there is a general shoulders-arms mobility routine to help fix this.
