Hello, I’m having problems whit my advanced tuck front lever (knees perpendicular to the ground). When I’m trying the position whit good form I seem to feel a lot of pressure in my right shoulder blade. maybe rear deltoid?. And sometimes it just pops and gets out of the retracted position. I don’t feel any pain only pressure. And when I’m doing it whit bad form (little bent arms) I feel all the pressure in my lats Is this a lack of scapular strength? this seem to happen in my right shoulder blade, I have a little bit of scoliosis so the left side of my high back is stronger. If it is a lack of scapular strength could you recommend some exercises that could help to fix it? Do I need to go back to and easier progression? Do I need to focues on scapular strength exercice?
