Hey @Alessandro Mainente,
I am freaking out a little bit right now...today during my gymnastic class on my faculty I tried just normal, basic pullup on high bar, and I experienced pain in my right shoulder, front delt or something else located there. I did proper warm up like always, and this was in the middle of the class so I was pretty warmed up...I have never before experienced shoulder pain during pullups. I tried later during the day, twice, just few reps to see is pain still there, and it is. I am even more disturbed because, one my friend have same pain in the shoulders during pullups, and his shoulders are completely f*** up...he needs to go on surgery (that bad). You asked me before what did I changed in my training, so...last 2 weeks I practice handstand daily, on wall, chasing endurance, strength and trying to find balance, also I am stretching my shoulders daily, before handstands, short, just to open up shoulders a little bit. I know that handstands are pressing skill (front delt, triceps), so I am maybe risking to create shoulder imbalances, which I am trying to compensate with higher volume of rings rows once per week, and scapula retraction exercise. Is this a problem, shoulder imbalance? Or maybe just overuse of muscles? I was wandered how professional handbalancers keep their shoulders healthy, but now I realized that most of them had severe injuries in their careers.
Please some advice/help.
