with hitting certain weights, especially on bench, the two things that move it are muscle mass and technique. Either you dont hold enough muscle to move the weight, or your technique is bad. If your other lifts are decent and its benchpress that is lacking I would suggest looking into lifting cues that help you maintain good technique.

But if youve been going to the gym consistently for 5 years, and still struggling to move up weights I would suggest start looking outside the gym for areas to improve. Diet, Sleep, Water consumption being the big 3 to look at.
