So for about three years now my chest has been doing this weird thing. I have no idea whats causing it and everyone I ask is more confused than me. I tried searching for it online but no luck yet. I even asked EliteFTS and they didn't know.
Basically if my shoulders are relaxed forward for too long (it doesn't take long actually) and I retract my scapula too quick, I get this instant and very forceful reflex/spasm. Also just touching the inside or outside of the pec makes it react. It also happens to my forearm. If my arm is in a flexed position then extended it will sometimes kick back up.
If I resist it too much as it resists me it can be slightly painful. Almost feels like its ready to tear.
I've tried all I could think of. Less training, more stretching, more sodium, bananas, more waters, whatever.
I'm starting to notice it in my lats too when I reach for things but its not nearly as dramatic.
So, any ideas?
