The dreaded poverty bench.
So just to be clear you throw around the 40s full ROM for lels?
Failing off the chest and feeling weak in the bottom/with a pause is almost always a tightness issue unless you’re in that 90% 1RM + range. You are never tight enough in your set up for bench.
Like tightness form/technique is also never good enough. Post a vid of your near perfect form because your “training instructors” probably have low standards and should not be suggesting that anyone be slack with improving technique, unless they themselves are powerlifters/coaches and even if then it’s still shit advice.
I’ma not post technique vids here because this isn’t a formcheck but you should look them up and apply what you learn. To think that your bench form is good enough is not the right mindset.
Short answer is yes… to everything.
Your stats don’t appear too bad but at your height there’s a lot more muscle to be added onto your frame.
Given the programs you’ve run maybe running some hypertrophy oriented programming for your upper body will likely do you good. Almost any muscle you can pack on your upper body will assist your bench as prime movers, stabilizers or just thickening you up and reducing ROM. Progressively overload upper body musculature for all kinds of bench gains.
Chest, Triceps and Front Delts are the movers. You’ve mentioned the latter two. What of chest tho? Whatever the answer none of these muscles can be too big. Nobody fails a bench because their triceps were too big. If you want your bench to go up you’ll need to get these muscle groups bigger/stronger.
Even with just the three muscle groups that do the moving there’s dozens of exercises to be done and more importantly potentially neglected. Presses at various angles from vertical e.g. OHP to horizontal, to vertical in the other direction e.g. Dips will all pack on muscle. Throw in isolation work too but it’s easier to progress on compound movements/ more bang for ur buck.
Don’t forget the rest of the upper body tho (feel free to disregard lower body #skiplegs). The back, rest of the delts, arms and forearms all hep with the bench. A minimum you should be incorporating and progressing some rowing/horizontal pulling movements in your training.
