Today's session was quite disappointing... my left shoulder kept giving way on seated military press and incline dumbbell bench. Even with relatively low weights, it would get to a certain point then just fail, before I began to struggle.
I've always had odd shoulders, I'm not sure if double jointed is the correct term but basically I can (but don't) do this:
What would people recommend I do? It doesn't particularly hurt, just feels very weak afterwards. My right shoulder felt like it was going to do the same but wasn't completely giving way. I was getting a similar feeling on bench press, the higher I positioned the bar up my chest the more it would feel weak. I don't have disproportionately small shoulders, if anything they are one of my bigger areas, but I was struggling to incline bench 10kg dumbbells when for my barbell sets I'm doing 40kg+.
Felt like a little girl!
Are there any shoulder supports that would help keep them solid? Or recommended shoulder exercises?
