Sorry, I know this is a long post :oops:
Started with BtGB 11 months ago. Never had any problems or aches or anything, always doing things slow and steady (just at the end of my 3rd cycle, where it should have been between 4th & 6th). 2-3 weeks ago my shoulders started to act funny.
I hurt my left shoulder some 2 years ago when trying to learn HeSPU on my own. My doctor said I overloaded the ligament and that I should rest it for a while. So I did nothing for 6 months and then started doing Pavel's Naked warrior for some 8 months before switching to BtGB. That hurt left shoulder always felt strange and kinda weaker then it should be, but it went away as I started to use Ido's shoulder routines. The only relict of that incident was that sometimes during planching I felt like my left shoulder is trying harder and getting tired faster than the right one, but overall it was getting better in giant steps. Before it started hurting few weeks ago, it was 99% fine. Now, it hurts badly only 2-3 second AFTER planching. During planching, it's ok. As soon as I come down from planche and my muscles stop contracting, it hurts for few seconds and then stops. It's not the joint that hurts, it's deltoid, but more from anterior side.
Right shoulder, on the other side, was healthy and problem-free till few weeks ago. It just started to feel very strange during handstand. It doesn't hurt; it feels like I have to rotate it a while till it "clicks" back. Of course, that "click" never happens, and it feels like this all the time. Left shoulder hurts only few seconds after doing planche, but I feel this discomfort in my right shoulder constantly since it first appeared. Again, it's not the joint that hurts; it comes from the deltoid.
It's important to notice that both my shoulders started hurting after almost 3 months of SSC, so it's not like I tried something above my abilities and hurt myself.
Few possible reasons come to my mind:
1. Bad posture - I realized recently I have really bad posture, my shoulders are always pointing up and forward and I'm hunching a bit. When trying deliberately to hold my shoulders down and backwards like normal people, my planche either hurts less or doesn't hurt at all. It is, however, possible I am pushing my shoulders down too much as planche becomes way harder. Right shoulder feels better when I try to push floor away from me during the handstand, discomfort is almost absent. Again, I was doing planche and handstand in SSC 3 months before the shoulders started to hurt.
2. Volume - I was doing my SSC for 3 months, 2 times a week during the summer due to the going to the beach and summer activities. I decided to go for one extra month of 3 times a week (this month) to cement the progress. Everything I do in this SSC feels easy by now, but again, shoulders started to hurt few weeks ago.
3. Structural imbalances - I noticed my pulling strength is developing rapidly in comparison to my pushing strength. I'm doing L pull ups, flat tuck rows and something between reverse chin-up and reverse muscle-up, while my push ups are stucked on hands at hip level since February and my dips were a total waste of time for the last few moths because I was doing them completely wrong due to the bad posture. Only my partial ROM HeSPU is ok, but still...
4. Hand position - I was placing my hands less than shoulder wide before. It seems shoulder wide or just slightly wider relieves the discomfort. This goes for both planche and handstand.
I'm doing Ido's shoulder routines and Coach's wrist series during the cool down. Maybe doing them as a apart of the warm up could help?
Any advice is welcome.
