exactly what the title says. my left should just does not seem to want to cooperate at all when i do chest exercises. on my last set i typically do 8 but around 6 when i do anything chest related my left arm just stops midway and just will not move anymore and it feels like the front of my shoulder is going to just snap. it feels like i need to crack/pop it but it never does.

should i just keep at it and keep pushing or does this sound like an issue i will need to get fixed or deal with. i have been goin to the gym for about a year and a half and my max bench for 1 has only been 205 because of my shoulder. i progress in everything else though so i know i am doing things right for myself.

any advice? thanks.
