ive been doing the bench press for a month and a half now with no training. just reading up on it and watching videos. Ive been trying to get my upper arms and forearms 90degree angle and flare them out like how my arms are in my avatar.
once i hit the heavier weights (more than 100) ive been experiencing pain INSIDE my shoulders most likely rotator cuffs.
should I try to tuck them in like a powerlifter?
and yes i do plenty of shoulder warmups
